It all starts with a 100% natural ionic mineral nutrient solution that comes in a dry form.

To start preparing your nutrients, we pour our nutrients A into a 55 gallon container using reverse osmosis water. We are then going to mix the nutrients thoroughly and continuously in a circle motion until the nutrients are fully dissolved.

Stock Nutrients A primarily consists of Nitrogen, Calcium, and Chelated Iron. Then, we are going to add this bag which contains dozens of other trace elements and micronutrients necessary for healthy plant development.

Keep stirring your nutrients It can take 20 minutes or more to fully mix these nutrients until the nutrients are dissolved. Finally add more water until the level of the small hole which is in your container. This is the limit of where the water goes to.

Next we are going to prepare our Stock Nutrients B, however before mixing nutrients B, ake sure you have a separate mixing PVC pipe for nutrients B. It is essential that you don’t cross contaminate even one drop of nutrients A into nutrients B.

Once finished add your suction tubes into the nutrient containers and connect those to the dosatron.

The dosatron will dose the concentrated nutrients at a 1 to 300 ratio with water and this nutrient rich water sits in a gravity tank which automatically fills up the towers on an as needed basis.

Contrary to conventional hydroponic farming where a different nutrient mixture is needed for each crop, this ionic mineral nutrient solution can be used for all vegetables, herbs, fruits and flowers which can be grown on aeroponic towers.

Aside from the purity of the minerals and the quality of the nutrients used to make the ionic mineral nutrient solution used in a Tower Farm, its uniqueness lays in the fact that only one single nutrient solution is needed to grow all crops!

Contrary to popular belief, hydroponic and aeroponic crops are just as nutrient dense as crops grown in the soil

The same nutrients found in soil are also found in the nutrient rich water used in hydroponics and aeroponics.

Although it may look like just normal water that we are using, we mix a natural mineral nutrient solution that is dissolved in the water providing all the essential minerals and trace elements including macro nutrients such as Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, and sulfur as well as all the micronutrients including boron, copper, manganese, molybdenum, zinc, and many others.

With aeroponics, plants can absorb these nutrients directly from the water, resulting in crops with the same level of nutrient density as the best soil-grown produce.

This is a great concern because, there is a lot of misperceptions of nutrient density of soilless crops. Firstly, aeroponic crops are not deficient in nutrient density when compared to soil grown crops and secondly they are bursting with flavor.

Here is how it works, all plants require nutrients including minerals and trace elements whether they are grown in soil or in a soilless system such as hydroponics or aeroponics.

In aeroponics, we use a 100% natural ionic mineral nutrient solution which is soluble meaning that it dissolved in the water which is then used is used to irrigate and nourish the crops. The nutrients used are split into Nutrients A and Nutrient B. Nutrients A is predominately made up of Nitrogen, Calcium, and Iron. Nutrients B is made up of Potassium, Phosphorus, Magnesium. There are also dozens of other minerals and trace elements as well.

Nutrients A and nutrients B at dosed at a 1 to 300 ratio automatically using what’s called a Dosatron. The nutrient water sits in this gravity tank and feeds the plants with this solution providing the exact amount of minerals and trace elements that crops need to thrive.

According to various scientific comparative studies which tests the nutrient density of aeroponic crops vs the best grown in the soil, aeroponic crops rank as high as the best grown in organic farming with very high levels of antioxidants, flavonoids, and nutrient density. This results in a superior tasting crop as well.

Employing vertical agriculture techniques for cultivating Choy Sum and other Asian greens has become increasingly popular with the advent of Tower Garden technology. The various models available, such as Tower Garden Home, Tower Garden Flex, and commercial Aeroponic Towers, provide optimal environments for the growth of these leafy vegetables.

Choy Sum, also referred to as Chinese Flowering Cabbage, is a prime example of a rapidly maturing plant that can be harvested within 40 days of planting. Ideally suited for cooler temperatures, this leafy green thrives in a range of 50°F to 70°F (10°C to 21°C).

In addition to Choy Sum, Tower Garden technology is highly compatible with cultivating a wide variety of Asian greens. Some of these greens include Bok Choy, Tatsoi, Mizuna, Chinese Broccoli, Napa Cabbage, Mustard Greens, and Amaranth. This versatile technology allows gardeners to produce a diverse array of nutritious, flavorful, and sustainable crops in an efficient manner, without the limitations of traditional soil-based agriculture.

From a “cash crop’ perspective, a Tower Farm operator farming in a climate controlled greenhouse environment should mainly focus on leafy greens and aromatic/medicinal herbs.

Although over 200 different crops can be grown successfully using our aeroponic tower technology and fertilizer solution, when it comes to farming vertically indoors, the overhead cost is calculated based on each square meter of operation.

Leafy greens and aromatic herbs do not outgrow the radius of the tower reservoir. It translates in more towers being able to fit within a specific area in comparison to growing tomatoes, cucumbers or any other vine related crops. When growing tomatoes or squash, the plants need to be supported by an outside structure.

When considering growing tomatoes, cucumbers, beans or eggplants, there are other agricultural technologies which can compare to our towers in terms of crop yield and quality.

However, when it comes to growing leafy greens and herbs (aromatic and medicinal), we are in a league of our own, where no no other agricultural approach can compare to our aeroponic tower technology: aside from a staggering superior crop yield, our “green crops” feature a scientifically proven increase in nutrition density, antioxidant activity as well as in phenolic values (healthier, tastier, more fragrant and stronger texture).

Growing leafy greens and herbs that are so superior in terms of nutrient density also means more ‘robust’ plants featuring a stronger natural defense mechanism (no pesticide needed) and a significantly extended shelf life.

Yield varies in any growing system by crop, weather, seeding rate, and other factors. In good growing conditions, lettuce, herbs, and leafy greens will have an average yield of 150g to 200g per port per 21-28 day growing cycle.

Yield varies in any growing system by crop, weather, seeding rate, and other factors. In good growing conditions, lettuce, herbs, and leafy greens will have an average yield of 100g to 175 g per port per 21-28 day growing cycle. Yield for fruiting vegetables like cucumbers and tomatoes depends on the variety and season.

Here are the average crop yields which we experience at Agrotonomy:

• Tomato cherries: up to 12 to 15 plants per tower maximum = 20 to 40 pounds per plant depending on the variety.
• Tomatoes “regular/ big size” up to 12 to 15 plants per tower maximum = 40 to 50 pounds per plant depending on the variety.
• Cucumbers: 15/20 plants per tower. A cucumber can vary between 100 g (or less) and 250 g. We can harvest about 15-30 cucumbers per plant (many more depending on variety, i.e. lemon cucumbers and other specialty varieties).
• Strawberries: 52 plants per tower. Depending on varieties, we have experienced from 100 g to 2.5 pounds per plant (whether we are growing wild strawberries varieties or large fruit varieties).
• Eggplants: up to 15 to 18 plants recommended per tower maximum = 6 to 10 pounds per plant depending on the variety.
• Leafy green and herbs: 52 plants per tower. From 100 to 175 g every 3 weeks . Once again, it all depends on the crop: it takes much longer for basil than it does for arugula… depending on varieties, harvest cycles vary from 14 days to 60 days with harvest cycles every 3 weeks on average.

Once again, the crop yield of a plant will depend on the quality of the seeds, the variety, the growing conditions (light, humidity, temperature, air circulation, elevation, EMFs, etc.).

At the bottom of the ‘beyond organic’ section of our website, we publish a comparative scientific study titled: “Assessment of Total Phenolic and Flavonoid Content, Antioxidant Properties, & Yield of Aeroponically and Conventionally Grown Leafy Vegetables and Fruit Crops. A Comparative study”.

As irrefutably proven throughout this extensive scientific comparative research, Tower Garden® aeroponic commercial systems produce 35% to 50% crop yield increase in comparison to soil-based farming and conventional hydroponics.

Gourds are extremely prone to mildew and fungi. Like with all cucurbits, we advise you to have a growing strategy allowing the plant to grow on a structure rather than growing on the ground.

In fact, gourds growing on the ground are prone to pathogens which can contaminate the entire tower. Like all cucurbits (cucumbers, squash, pumpkin, loofah…), gourds grow huge root systems.

When the powdery mildew starts showing signs on the leaves, we advise you to mix a tablespoon of cornstarch per 5 L of water and spray such mixture on the leaves and stems (sometimes it works, sometimes it doesn’t depending on the level of infection… even if it does not eradicate the problem, such natural remedy does help with slowing down fungi infections.).

In terms of crop yield, gourds are generous plants which give lots of fruits.

We only recommend you to grow gourds for experimental purposes. Gourds are rarely grown to be eaten and we advise Tower Garden® owners to prioritize the use of their tower to grow food.

Nevertheless, gourds are also the perfect crops to grow with children from an educational perspective.

Bottle Gourds have been used since ancient times for a wide variety of uses. Aside from being edible, Bottle Gourds are traditionally dried and then used as storage containers, bottles, instruments, and decoration.

Urban Smart Farms is an indoor aeroponic Tower Farm inside the Orange County Convention Center in Orlando, Florida.

Regardless of varieties, we strongly recommend growing beans using Tower Garden® technology.

When growing beans on a Tower Garden®, use a grow cage for support enhanced with crisscrossed kitchen twine giving support for the tendrils.

We want to change that by proving to the world that growing beans commercially on an aeroponic tower is one of the most viable solutions in terms of crop yield, nutrient density, and pest-free option.

The time has come to grow some protein-dense crops on your tower: grow beans (with a planting strategy), all kinds of beans!

We highly recommend growing Kohlrabi and eating it raw instead of cooking it. Kohlrabi just needs to be peeled and either grated or sliced finely using a mandolin.

It has the crunchy texture of radish with an omnipresent pallet reminder of cabbage flavor. We love to grow & eat Kohlrabi!
