Commercial Indoor Urban Garden Farming profits will have to keep up with rising utility costs. Air Freight Shipping FRESH non seasonal cost will also increase. The only non inflationary energy source is the sun. Facilitating growing  specialty produce / product  Outdoors in Midwest to Northern zones has potential. So, sweet Italian frying peppers cost 3,00 ea in the Big city. One garden can produce over 100 peppers. Midwest outdoor gardening starts in June, goes to Sept. that season is extended by 3 months moving plants indoors for frost protection. The Vertical Eco Gardens can be utilized to tap into this non inflammatory energy source and extended outdoor growing time by its gardens being moved on mobile stands indoors. For commercial growers, who grow cannabis for instance, this could mean lowering costs significantly for these three extra months of natural light and conditions. Everyone has to compete in the market, and lower overhead means a reduction in product cost or an increase in profit margins. Using the sun produces better product at a lower cost.

Lets start with the latter. A business plan for any venture will want to establish your Niche, Right? Your market research should reveal who is growing what, and selling to who, and at what price. Based on this formula, I would not consider doing research on another urban lettuce farm, unless I could compete in price and quality. I am not an expert. However, my first thoughts for indoor growing would be cost of utility as a major overhead. Again, I am not an expert, but I also would be hard to convince that lights could do better than the sun. Not to mention the cost of facilitating an indoor grow. Will your projections serve that amount of debt? How about the cost of leasing, renting or the long term liability of buying? Industry has left for foreign soil, abandoning industrial sites, so finding a facility might not be too bad, unless the facility was much newer and had all the modern amenities. Niche in a crowded field requires looking at every station, from overhead cost, what to grow and who to sell to, to get the biggest return.

For example, If I had an Italian restaurant with a fussy chef, I would want to find a supplier who could deliver the tastiest fresher Italian Pasta or Stuffing Pepper for my customers. The cost might not be their main concern. And if I wanted to save on utilities, I might want to use the sun and a facility that cost less. Being able to Garden in Northern Zones might not be as difficult nor have as short of a growing season. By facing the Vertical Eco Garden south, it functions like a solar panel. Sun that is lower on the horizon compensates by hitting the vertical garden more directly. The Northern and Midwest gardening season can start earlier and grow later into the autumn. If frost is in the forecast, the Vertical Eco Garden mounted on mobile stands can be moved indoors, where the stored solar heat could keep them from freezing saving utility cost thru the night. I imagine they could be linked like kiddie train cars at the zoo. One more advantage, the potting soil amending and exchange can be automated.

Restrictions To Conventional Home Gardening requires High Yield From Less Resources. Typical restrictions involve city ordinances, limited space, shaded or Northern cold and South West arid climates. Container Gardening has been at the forefront to address these variables and is also a great option when dealing with physical limitations. There are also informal social influences that are pro and con, but those will not be addressed as they are voluntary, and you have a choice. Mt feelings are two fold. The first is that gardening is not an identity. Having said that, In face of any adversity, it is a good idea to choose between solving a problem VS having a problem. And in seeing the problem as an opportunity to grow, we will continue to the next opportunity on how, what and where to grow your vegetables.

High vegetable yields from less resources requires some planning. There is an abundance of information available on the internet that will give a solution to most challenges on small space gardening, pest control and types of plants, including nutrient content. Because we are focused on higher yields of nutrient dense vegetables, this article will use more natural processes that utilize space, resources and yield. For Nutritional and Medicinal content of vegetables, I would refer you back to the internet. The question that often asked is, Can you grow enough to make it worth while? To answer that question, three of Vincents “real food” bush beans have more nutrition than the contents of an entire can off the store shelf. Looking at it from that truth, what you see behind Vincent is an entire store shelf of nutrition. As you know, when it comes to kids and vegetables? If they grow them, they will eat them. So, you can cost effectively grow enough nutrition to make gardening worth the effort, and also introduce your child’s hypothalamus to the “Real Food” source for when they crave nutrition.

No concerns about trampling the plants with wee
ones weeding, because there is no weeding in container
gardening. Just give them a watering can and let them
have some fun.

Container Gardening is a very efficient way to utilize space and resources.
There are many to choose from. Some are ridiculous and expensive novelties and some are very innovative and worth consideration. You can go beyond the typical plot of garden pots with a few innovations and by paying attention to detail. For the money, garden pots, though labor-some will produce adequate yield of nutrition applying a little science via easy affordable upgrades. To begin, what is more important than the housing that contains your potting soil, is the potting soil. The key ingredient in a productive natural potting soil is free, at least for now. That key ingredient is air. We cannot talk about aeration without including drainage. The conventional approach to a good potting soil and container is having good drainage. And the most common problem in container gardening is over watering. This is because too much water and not enough drainage displaces air. There is an article by #TOMOGREN titled “the real dirt on potting soil’” that actually measures the time it should take for water to drip out of the bottom of a pot. It’s about 3 seconds. However, since that article, there are new soil-less growing mediums that provide a higher levels of hydration and aeration combined. There are also amendments that help to prevent over watering. The reason for balancing air and water in your soil is to encourage the friendly microbes and prevent bad bacteria. Excess moisture that displaces air causes an anaerobic condition. This will incubate anaerobic bacteria. Those are the “bad guys” that Toledo had to deal with in their water supply. That is another story, but is relevant if you want to contribute to clean water. You see, an aerated soil provides the oxygen that the microbes in your soil need to produce natural phosphorus and root growth hormones. In short, It was chemical phosphorus runoff that caused the algae bloom that sunk to the bottom of lake Erie where the good bacteria consumed all the oxygen when the algae decomposed. This created an anaerobic environment incubating the bad bacteria. Sorry about the long sentence, but the point is, plants do not absorb chemical phosphorus very well. They prefer the natural foods just like smart humans. Lets talk about what a good bio-intensive, aerated potting soil would look like and then we will move on to the variables of location, conditions and plant types.

Earlier mentioned, were new soil-less mediums and this is key. Not included in “NEW” is peat moss. Peat moss is OK as the readily affordable and available standby. Most potting soils are mostly peat moss. Here is something you should know. It comes from pristine natural environments and is not a sustainable medium. There are operations that farm it VS mine it. Mechanically, once dry, Peat Moss is hydrophobic. It repels water. Anyone who had a flowered pot dry out, knows it has to be replanted, or anchored to the “bottom of the well” until is wont float. The nature of combining high drainage through a hydrophobic growing medium is problematic, unless you have drip irrigation on a timer or find the time spent using the garden hose and watering can relaxing. That’s great, but for the efficient minded gardener getting the ‘biggest bang for the buck’, I prefer Premium Coir.

This block of coir (ground coconut shells) was the size of a big shoe box until it absorbed 9 gallons of water. Notice the center is still dry. Coir works like a sponge absorbing water while providing a non-compacting structure that prevents the displacement of air. Lets not stop there. If a bio-intensive soil will need to combine higher levels of air with water, here is another ‘jewel’, and it too is sustainable. Boiled Rice Hulls. It takes a little time, but notice that rice hulls sink. Not only do they retain their hull shape, which would provide aeration, they also retain water. And because it is an organic cellulose, it will decompose slowly over time. Make sure they are Boiled Rice Hulls as the non boiled have starch and sugar that will rob your soil of nitrogen known as #Nitrogenlockup. If I were going to get into the potting soil business, I would not try to profit from the cost of shipping soggy bags of peat moss. I would simply provide a kit of lightweight absorbent growing medium with amendments and instruction to “Just Add Water”.

This also applies to another of my favorites for hydration with aeration. Now getting into the other components of a good potting soil, I like Forest Compost. Key word here is compost. Forest compost has wood chips. If they do not crumble in your hand, they may rob your soil before they give back. A little chunk of decomposed wood in your soil also absorbs moisture and provides aeration. The other gift from nature in forest compost are the leaves. Leaves are the best compost material known to gardening. Think about how deep those tree roots go for clean water and nutrients before they send their colorful autumn canopy quilting to the forest floor, or to your yard if that be the case. Go from yard work to gathering compost materials changing one simple intention.
Having gone from providing information to being philosophical, I will give the % mixture of a good Professional Potting Soil to get back on the subject.

Professional Natural Bio-Intensive Potting Soil Formula
Given in percentages, the soil-less portion (coir, peat moss, or like) should be no less than 2/3rds or 66%. Forest compost should be 1/3 or 33%. Of that volume 10% top soil, 10% natural hardwood charcoal, 10% boiled rice hulls, pearl lite, or comparable. Last but not least, the soil amendments. Of these there are many, and the ones you choose and the amounts you use, will be determined by the type of plant per soil (pH) and soil culture. Following the directions on the packaging will work in general. This goes for the containers and growing medium as well but more on that later. The most common and most used would be bone meal, a microbial plant food, or worm castings, and blood meal. There are also fish and kelp pellets. Natural Liquid plant foods used for periodic feeding would be a fish emulsion, or something comparable. These would have to be a non burning type of nitrogen. There is a way to ‘kick start’ your microbial culture. It is called #Charcoalcharging. Simply mix your hardwood charcoal with the compost according to the articles about 10 days before mixing it into the potting soil. Note, hardwood charcoal is more affordable as a natural hardwood cooking / grilling product. But it is very messy to break up. You will have to trust me on this one. Unless you like to shower under a Garden hose, there are many sources of charcoal as a soil amendment, and a little bit goes a long way.

To give you an idea on how many vegetable you can grow from a lesser amount of potting soil, having a healthy aerated root zone, these are 25 Sweet Italian pepper plants producing abundance’s of ideas for my pasta palette, using only 7 to 8 cu ft / 4 typical bags of a “Tom Ogren” amended type of soil.

Vegetable, Container, Location, and potting Soil Compatibility

You may not see pictures like this in your seed catalog. Here is the reason.
Most gardening instructions will give you the general guidelines to grow most vegetables. However, to get high yields, you will want to cater to what the plant needs. Eggplants are hard to grow because they like a rich soil with frequent watering in a high drainage, if using a common potting soil. In a coir based potting soil, the drainage and watering are less. These Fairy Tale eggplants are located halfway down on a continual root zone in the Vertical Eco Garden. In that space, they have just the right amount of hydration, food and air. Above them would be beans and peppers as those do not need a lot of hydration and nitrogen. Lower on the rooting chamber would be the Broccoli, pickle bush cuke’s and Zuke’s. Cabbage and other vegetables that like rich soil and increased hydration are usually on the lower areas. To simulate this in a container, you can mix and test the pH of the soil culture per each plant specifications. A good tool to have in addition to a pH meter, is a seed catalog that will give the soil culture. Johnny’s Selected Seeds among others will provide this. Another great service that the seed catalogs provide are the Compact Bush Variety of Vegetable Plants. Available in both Heirlooms and hybrids, these were, and are being developed for the Urban and Suburban gardeners.

To give you more of an appreciation for getting higher yields from less resources, these are an Heirloom Compact Silvery Fir Tree bush tomato. They have a slender leave allowing more sun penetration so you can plant them close together or with other plants that like shade.

Tomatoes and peppers like abundant phosphorus. For example, in that pot or container, the soil will need more bone meal. Tomatoes have aggressive root systems and are hungry eaters. You will use a bigger pot or container and hold back on feeding until the fruit start to form, then feed every 7 to 10 days.

Get a pH meter. With the meter comes all the soil pH needs of each plant. To save time, make up a small batch or one gallon of your mix and test the soil. It is easier to formulate a small amount, and do the math before you mix bigger batches. OR, buy an ‘Off the shelf” potting soil and add the amendments mentioned.
To get more assurance that your soil will have aeration, you can line your pot with a couple of layers of Weed Guard material or use a product called Smart Pot. Some roots will grow into this material for more aeration if needed. Plants are smart. It’s called Plant Intelligentsia. Just provide some options, learn to be still, and observe.
Climbing vegetable plants are the original vertical gardening ruler. But there is a reason why commercial growers grow bush varieties. Fundamentally, climbers are indeterminate types and will produce for an entire season. Bush varieties, though produce over a shorter period, will put more energy into yield VS vines needed to climb. This is why commercial growers who are conscious of cost will go with bush varieties. My preference are the bush varieties as I usually grow and process a wider variety in a small space, in a short Michigan Season. For me, the best of both worlds was to grow the bush variety of vegetable vertically.

When, Where and What Vegetables to Grow
First of all, do not be discouraged if the seed catalog requires Full Sun. Not so, when your soil can give your garden the advantage of utilizing only 5 hours of sun instead of full sun. I find it questionable when full sun is required, yet plants will wilt in the mid summer mid day heat. So….. There are also shade tolerant types that do real good with less sun and partial shade. Even a Bell Pepper can grow in shade. In addition to having different soil cultures, another advantage of container gardening is to use plants with a bigger canopy to shade the ones that like less sun. As a rule, an open south exposure is best. With a south exposure, you can also start gardening earlier in the spring or later in the autumn if you use a vertical Gardening configuration or system. This is because a vertical surface, like a solar panel, will catch the sun lower on the horizon during the spring and fall season. If gardening in pots or other containers, these can also be stacked or shelved if there is a backing that will catch and store the suns warmth earlier and later in the day. For an east to west exposure, plants that require less sun, work great. There are many types of greens that grow in many types of conditions. Some are frost tolerant and great for early spring and autumn into early winter gardening. Swiss will “rock your world” if you want to harvest a few leaves at a time for a long season.

Looks hopeless, and your tempted to grab the pesticides. DON’T, this works. And with your help, we will develop it to work on other kinds of infestations that don’t inhabit my area. It is difficult to get anything to stick onto the leaf of a cabbage or broccoli, and have it survive the rain.

Notice how the Vertical Eco Garden Dessert Dust becomes remnants of the water spots. It survives the rain. And also notice the new growth that has been abandoned. This is a good type of abandonment.

Here’s the formula and where we are to date:
Diatomaceous earth ( sharp glassy silica particle) is a long time proven safe standard for getting rid of creepy crawly aunts, crickets and roaches etc. It irritates their joints. And it is easy to sprinkle it on a floor or  around the base of a plant. But how to get it to stick to the leaf of a Brassica? Not in the picture, use Talc. A generic baby, bath or shower powder will work for small crops. For bigger jobs, talk to the local coatings / paint co. They have one that is used for making flatting paste used to dull  glossy finishes.  They should be able to give you a good price or a resource. The small cup has pea gravel used to keep the ingredients dispersed.

The formula I used was 45% talc, 45% Diatomaceous Earth and only 10% borax. Borax is also a long time favorite for repelling aunts and worms. But there is a precaution. More is not better.

Even with only 10% borax, it burned this eggplant leaf. A previous formula having a mixture of all the ingredients at 1/3 each resulted in more severe burns.  The current  formula with borax at 10 % did not damage the brassicas, but because eggplants, tomatoes and beans etc.have a more textured leaf, more Desert Dust was absorbed. So, maybe cut the borax back a bit for those plants, and or use less early on as prevention. To date, the 10% borax got rid of worms, Japanese beetles and slugs.

Here are some precautions and directions for making the duster from a re-purposed can or container.

If you read the safety instructions on the container of Diatomaceous Earth, it will say to not get it into your eyes. I can testify to that. Even a little is irritating. So, after you make your duster per these directions, make sure your back is to the wind when you dust. With all the ingredients combined with the pea gravel, or something comparable, close and tape the lid thoroughly. Remember, the pea gravel has weight and you don’t want to be the target of your own dust storm. After the lid is secured, shake the container. After the container is thoroughly shaken up, punch holes in the lid. Now your ready to dust, and taken from an old Irish homily, may the sun be on your face and the wind at your back. And remember, this is a non pesticide w o precautions of over-use.  So, if the bugs come back, wack em again. Real simple.

What is the most over-looked ingredient in a good potting soil?

            How do I go about making or finding a professional potting soil for professional results?

                         Can I use a professional potting soil approach in a box / bed garden?

        In this Blog I’m going to include some information I’ve learned from an article on the web site, www.allergyfree-gardening.com, titled ‘The Real Dirt on Potting Soil’. written by Tom Ogren who is the author of five published books, has a M.S. in agriculture / horticulture and taught horticulture for twenty years. In addition to this he started growing when he was five years old, 57 when he wrote the article and somewhere between then and more recent times he owned two wholesale – retail nurseries. He mentioned a couple of potting soils he favored but could no longer find them and began to buy less costly potting soils and amending them considerably. I will only draw on the points he made in that part of the article, but I recommend this as a good read in general, especially for amending and or making a professional potting soil. 

        We have put into practice, and have been getting good results by applying Tom’s principle approach to amending or making professional potting soil. In a paragraph subtitled Perlite, he points out the pros and cons of high drainage using Perlite. These pros and cons are, better root development via more aeration, but will require more frequent watering. Aeration is key, and air is the over-looked ingredient. 

        Here is how it works:   The main functions of the growing media are to provide nutrients, water, gas exchange and anchorage. Lets first focus on gas exchange because this involves air. The gas is a phosphorus that is the bi-product or production of microbes breaking down organic matter. The microbes also provide root growth hormones. Think of your potting soil as yogurt culture. The bacteria is friendly and it needs air to thrive. Bad bacteria will be killed or kept in check by air. So air is key. In the past, the practice has been to increase drainage with Perlite. This is because Perlite provides air and increase drainage. Air via Perlite also keeps the roots from drowning and keeps the soil from compacting. Both water and compacted soil displace air. However, high drainage results in increased run off or waste of nutrients and water. Also, maintaining moisture is key for sustaining a bio-intensive root zone. So, the down side to high drainage is that run off  of water and nutrients are costly and messy. Air, on the other hand is free (at least for now) and so are the gases that the microbes produce. There are other materials that work better to increase both aeration, moisture and nutrients in a potting soil. Though they are not widely distributed in the major retail stores yet, they are worth the trip to the hydroponic store, and worth the increase cost of shipping if buying on-line. They are less expensive and work better in the long run. These are referred to as sustainable and soil-less mediums.  

        The two most common are boiled rice hulls and Coir (ground coconut shells). Boiled rice hulls replace Perlite, and Coir replaces Peat Moss. All of the plants in the pictures in this article are growing in potting soil that is approx 2/3 Coir and Boiled Rice Hulls.. Coir has safe Ph levels, is more coarse for aeration and absorbs more water and nutrients. Likewise, Rice Hulls also absorb moisture and will hold their shape (see Sink or Swim blog on rice hulls) to trap air. Because they are organic, they will slowly decompose and provide nutrients. As mentioned, Boiled Rice Hulls also absorb moisture and cost about $1.50 per cu ft when purchased on site in small volumes. 

What is a Good Professional Vegetable Potting Soil Mix?

Organic Amending bed gardens and  potting soil for aeration

They sink. The Question is, What is significant about rice hulls sinking as it relates to using them in a growing medium? For these hulls to go from being suspended on the top of the water and then sinking to the bottom, they had to be absorbent. What can also be observed in the bottom photo is, they keep their hull shape after soaking in water for 24 hours. The cellulose make-up of  a boiled rice hull contributes to it’s ability to maintain some of its rigid characteristics after it has been exposed to moisture. This facilitates aeration in a soil needed for a microbial rich environment to produce phosphorus and root growth hormones.

The cellulose makeup and slowely resist decomposition, however,  the hulls are organic and do decompose. Many garden soils, potting soils and top soils, available in bags at retail stores will list compost rice hulls as one of their materials. So, in addition to providing moisture control, and aeration to the soil, we believe boiled rice hulls can be used as a nutrient amendment as well. Please read our previous blogs on boiled rice hulls and join in on the discussion.

Conventional Potting Soil Test

In order to discuss problems with Pocket Gardening, I first have to briefly talk about potting soil and validate the information. I will use the experiment in this picture. The above picture is of a potting soil test with mixtures of more conventional potting soil. These consist mostly of peat moss with compost manure and or forest products & a little top soil. Each vertical chamber in this Vertical Eco Garden, having 5 pockets on the front, has a different blend of potting soil. The only soil that was significantly different is the middle row. Row 3 started out of the gate strong but finished last. Visually, the soil in the first row looked like what a novice (me) would consider a nice rich earthy looking soil. It was rich, moist and beautiful. However, this produced a smaller compact plant with more secondary growth between the main branches & smaller peppers. The second row received potting soil that was used the previous year, and it was amended with a product called Organic Garden Tone by Espoma. The 2 main Ingredients in Garden Tone is Hydrolyzed Feather Meal and Pasteurized Poultry Manure. Since this was re-used (amended) potting soil I will touch on information on how to do that and then we will get back to the experiment.

I have seen directions for amending potting soil that required heat treatment in a clear plastic bag to be placed in the sun for X time at X temp to kill microbes. Then it said there were good and bad microbes but didn’t explain how to discriminate. The short answer, not found in the article is that bad microbes can live in compacted soil with little air because oxygen is of no use or is poisonous (anaerobic) and will inhibit or kill them. The friendly microbes thrive on air and produce stimulating root growth hormones and beneficial trace elements like nitrogen and phosphorous. The article said to add more perlite for aeration & vermiculite for more water retention. Instructions for testing drainage VS water retention said to pour water in the pot and see if it drains and how fast. This information was all after the fact regarding our test. Regardless of this, the second row did good. I think it was because we simply amended (re-mixed) with a bio-intensive plant food, and planted an heirloom that was smart and tuff. The reasoning was, if the potting soil worked the year before, it just needs nutrients and cultivation (loosened- up). The third row was an expensive $40.00 per 2 cu ft bag to be used for growing what used to be a weed, but now is a medicine. The Master Gardener in charge of the experiment thought it looked like the peat moss was too fine and would compact. The fourth & fifth row did the best. The forth row is called All Pro and is a Michigan based company that was purchased from a garden center in Byron Center Mi on sale for about $7.00 / 2 cu ft. It contained a lot of composted forest products. The fifth row was a home -made mix and had a lot of composted leaves with a little top soil. All of the soils used different amounts of perlite for aeration and we added Garden Tone to all of the soils as well. So, all of the soils had the basics of a potting soil described in the following, more or less. The first ingredient I will mention is the main medium, It is the bulk of the potting soil. The functions are to provide the plant roots with a home that will hold a good balance of air, water, food and stability (root anchorage). For this, Peat Moss has been the main source for a long time. However, other medium & sustainable types have come of age. Coir is probably the most used to replace peat moss because it has very similar properties. Some a little better (less compacting) & some a little less, (water / nutrient retention) but this isn’t rocket science if growing heirlooms. For a sustainable to replace peat moss go with Coir that is made for growing plants and not for bedding or as feed filler and just add a little more plant food per the same directions on the label.
The next amendment is compost. Compost is decomposing organic matter like manure with bedding of straw or wood shavings, or chicken manure with rice hulls or wood shavings (chicken liter), and forest products (leaves & wood etc).
Ideally, any compost will contain a full range of materials in different stages of decomposition from chunks to what looks a little like muck. This is the humus content, it is the residue from advanced stages of decomposition. Humus will hold 90% of its weight in water and it gives the soil stability for root anchorage, but it has little to no nutritional value. If your compost is too chunky and drainage is too high, vermiculite is added to retain water. If it is too mucky, add rice hulls, perlite and coir or peat moss along with plant food. Most of the compost should be in the middle. Not too fine or muddy and not too chunky. A bag of potting soil / compost should not be heavy and wet. What is desired is organic material that is decomposing (good microbes), not decomposed or not decomposed enough (nitrogen lock up). Chunks of wood for example, should be fingernail size and be able to crumble between your fingers. A few small sticks are OK for resisting compacting. The finer particle (humus) will typically compress and form when pinched between your fingers but a handful of the potting soil should not form or clump together when compressing a handful. This would indicate the humus content is too high. The next amendment is for air or aeration in the soil. Traditionally, this has been perlite. It usually makes up 20% to 25% of the mix. However, we’re about to change that with rice hulls.

For aeration, Rice hulls are the new kid on the block and this is what I want to talk about.You may have heard some bad reports on rice hulls. Well, there’s a reason for that. Rice hulls are either boiled or un-boiled. Boiled rice hulls are used by the nursery industry to replace perlite. I think this is preferred by their customers in the big cities who don’t want to deal with floating perlite in managing waste water, treatment and run off. Riceland learned the hard way on how to perfect boiling rice hulls. The problem was this, Sugars & starches are the first to break down in decomposition. When that happens it takes nitrogen from the soil (nitrogen lock up) So, Rice hulls used for aeration took nitrogen from the plants and then it decomposed too fast. I suspect this may have caused them to lose structure and resist compacting. With less nutrients then less aeration, the plants were stunted. The relationship with aeration and nutrients is this. Granted, roots need air, but so do the microbes that have the job of breaking down the organic matter and provide food. So, aeration is key. To fix the problem with the rice hulls was to boil the starch and sugar out of them.
Even this process had a learning curve. It required replacing the water between batches to get rid of all the sugar and starches. What is left behind is a SILICATE like hull shaped material, that now, free of sugar and starch, will not take nitrogen from the soil and will decompose more slowly while holding the hull shape to provide aeration. Here’s my thinking and here is how I want to incorporate rice hulls in the Vertical Eco Garden. Granted the boiled rice hulls are free from sugar and starch and are now a silicate structure, but are still organic, and it will eventually decompose. Although it doesn’t have the sugar and starch content that locks up nitrogen, it will still absorb nitrogen (nitrogen Lock-up) in a saturated treatment to initiate decomposition.

Regarding Pocket Gardens, We realize the Vertical Eco Garden resemble a pocket garden. And this is a problem because Pocket Gardening doesn’t work as well, especially for growing vegetables. In fact, we are the opposite in functionality. From ALL the pictures of pocket gardens I have seen, they must be using heavy compacted soils. Because the plants resemble our stunted pepper plants in the heavier, more compacted media in rows 1 & 3. My position is pocket gardening relies on heavier soils in an attempt to get root anchorage so the plants would not blow out in the wind also preventing the soil from drying too fast in their fabric. This is the another pocket garden issue. I won’t go into all the engineering water flow specs for Geo materials because that tends to get a tad boring. However, I will just say they are being misunderstood and are being applied backwards in most cases.

Mechanical Root Anchorage

Basically, in pocket garden materials the water flow specification of a filtering application is being applied to a drain design. So the water runs out too fast. To compensate, they go with either more humus or too much vermiculite. To make matters worse, they have resorted to combining organic (cotton, hemp, etc.) materials in the construction of pocket garden material to absorb or wick water. These won’t last long either, in or out of doors because they will become plant food. The Vertical Eco Garden goes in the opposite direction. Our roots anchor when they grow through the UV resistant geo material from the small pocket into the rooting chamber. This chamber can now use loose aerated mixes of medium. Water is utilized by using only one dripper set on low to feed the 5 growing stations below. This is a drain design application. This, along with root anchorage is the key difference. For example: When bush beans are planted, 15 plants will be watered by one single drip irrigation component.We are focused on our mission to get the biggest yield from the lowest cost, from the smallest volume of growing medium in the least amount of space.Growing vertical is just the natural consequence of that. So, another question that fits this mission statement is, why can’t the same amendment for aeration (boiled rice hulls) be used for a portion of the compost as well, increasing both aeration and microbial nutrition. The potting soil test indicates this is the direction to go.

I was looking at a back yard garden composter in a farm supply magazine. It showed a barrel full of what looked like oak leaves. I prefer Maple leaves. The advertisement said it could compost leaves in 15 days and it would contain the odor even with a rich nitrogen additive. So, in the same way as is practiced to decompose leaves we are initiating decomposition of boiled rice hulls. So far, they are decomposing. We think we can control this to the mid way point of decomposition. We don’t have big chunks and we won’t have the sludge (humus) because we are starting with a more uniform material. These little hulls will still work for aeration because so far, they are holding much of their shape. They don’t break apart, crumble or turn to mush.

The Vertical Eco Garden is currently getting high yields from 25 to 75 short to mid size heirloom varieties in only 6-7 cubic ft of potting soil, using a garden space of 5 sq ft. However, we’re pushing for vegetables from 90 heirlooms. This will be the results from having mechanical root anchorage in a loose non compacting aerated microbial rich potting soil. We’ve replaced heavier soils for a more aerated medium that provides a more bio-intensive environment. We have combined the best of aeroponic, hydroponics and geoponic in one system. Vertical Eco Garden has found ways to improve this by utilizing the rice hull amendment not only for aeration but also to extend the growth life of the potting soil. Theoretically, this is done by manipulating nitrogen lock up in the boiled rice hulls before it is added to the soil. Then it will provide both aeration and bio-intensity which work hand in hand. It just makes more sense. But let’s not stop there. What about rice hulls for water retention? Visualize this, Peat moss absorbs water like a sponge. In your head, do this little experiment for. Take a sponge and let it absorb as much water as it can and ring it out in a small bowl. Then let that sponge absorb water again and lay it on a dish. Which one will dry up faster? The water in the bowl (rice hull) or the water in the sponge (peat moss)? If you guessed the water in the sponge you are correct. Theorizing rice hulls can do more of the main functions of a potting soil, we are going to do another growing media test.

Mini VEG™ Vertical Eco Garden™

The picture on the right is our Mini VEG 9. It has three vertical rooting chambers. Each chamber will receive different percentages of rice hulls as a growing media. One will have 100%, the middle will have 75% and the third will have 50%. All of the same bush beans will be planted as a control perimeter. We will be sure to keep you posted.

The 2 pictures below are the growing stages and results of the potting soil test pictured at the beginning of this article. It also demonstrates big plants can come from what looks like a small pocket. But make no mistake, this is NOT pocket gardening.
