3. What is the minimum purchase for a Tower Farm (commercial towers)?

The minimum order for an automated commercial Tower Farm is as follows:

– Europe: 10 to 30 towers (depending on countries)
– Middle East: 50 towers
– Asia: 50 towers
– South America: 30 towers
– USA/Canada: 10 towers
– Oceania: 50 towers

A fully automated commercial Tower Farm system includes the nutrient distribution equipment and containers, the pumps, the irrigation system, the tubing, and connectors. It is indeed a fully inclusive system which is really easy to assemble. We deliver our aeroponic Tower Farm systems equipped with a fully automated irrigation system supplying the water and nutrients to each tower on an as-needed basis. For example, a tower growing strawberries or tomatoes will require more water and nutrients than a tower growing parsley. Our irrigation system automates the whole process regardless of the number of towers involved.

4. Can I purchase just 1 or 2 towers for testing purpose?

The minimum order that Tower Garden Ltd.’s headquarters in the USA would consider to sell for a test is a small Tower Farm featuring a minimum 20 to 50 towers depending on the country (see FAQ #1). The only way to test our technology on a commercial level is by using the towers in combination with its automated irrigation system which supplies precisely the water and fertilizer solution to each tower on an as-needed basis. Any lesser test would not be relevant to our technology as it would produce inferior results.

We sell our nutrients/fertilizers in bulk (1 nutrient set supplies 30 towers for 6 months/10 towers for 18 months). In other terms, such volume of nutrients would be overkill just for 2 towers. Our proprietary nutrient solution is key to our technology.

Furthermore, our Tower Farm systems are not “a novelty.” We have over 10 years of experience, and numerous Tower Farm references operating successfully in all climates including one similar to the one in the UAE (i.e., our partner Tower Farm True Garden in Arizona). We are not in the ‘testing phase of development.’

In the world of aeroponic vertical farming, we are not only veterans, but also we were the pioneers of such technology over a decade ago. We are not one of these “Chinese-plastic-fantastic-cheap-tower” without references nor track record!

Our Tower Farm systems are being used by over 100,000+ customers and hundreds of profitable commercial Tower Farms worldwide.

This is why we feel that if someone truly wishes to test our aeroponic Tower Farm commercial systems, it should be done with a minimum of 20 to 50 towers. Any less could not lead to conclusive results to benchmarking the potential of our technology on the commercial level.

5. What is the crop yield of a Tower Farm (and recommended crops to grow commercially)?

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. Whether growing beans, cucumbers or tomatoes, building outside grow cages defeats the purpose of farming vertically as it uses square footage which could be allocated a for more towers. A Tower Farm featured in a CEA environment is about reducing the water usage while increasing the crop yield by optimizing the space.

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 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 a True Garden and or Ibiza Farm:

– 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).

– Bell peppers: up to 20 plants recommended per tower maximum = up to 6 -8 pounds per plant depending on the variety.

– 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.

6. Can I become a Tower Farm reseller?

Only selected experienced Tower Farm operators can qualify as Tower Farms resellers. In other terms, in order to become a reseller, someone needs to own an active Tower Farm and have at least a couple years of tower farming experience before being eligible to resell the technology.

Tower Garden Ltd. does not grant territorial/regional distribution exclusive rights.

7. What Tower Garden size is right for my Tower Farm?

Tower Garden is modular in size and can be configured as follows:

Regular crops:

– 5 Pots (20 plants per Tower Garden) – 1.4 m high.
– 7 Pots (28 plants per Tower Garden) – 1.8 m high.
– 9 Pots (36 plants per Tower Garden) – 2.1 m high.
– 11 Pots (44 plants per Tower Garden) – 2.5 m high.
– 13 Pots (52 plants per Tower Garden) – 2.9 m high.

Microgreens:

– 10 Pots (80 plants per Tower Garden) – 1.4 m high.
– 14 Pots (112 plants per Tower Garden) – 1.8 m high.
– 18 Pots (144 plants per Tower Garden) – 2.1 m high.
– 22 Pots (176 plants per Tower Garden) – 2.5 m high.
– 26 Pots (208 plants per Tower Garden) – 2.9 m high.

At Ibiza farm, outdoors, we use the 11 pots (44 plants), model. Even standing at 2.5 m high, in stormy conditions, the towers will sway back and forth but will not fall. It is impressive to witness how resilient these commercial aeroponic towers are throughout rough weather conditions.

Of course, when outdoors like at King Tower Farm in the Philippines, high winds can mean typhoon conditions and this is why working with 9 pots (36 plants) maximum may be strategically better.

When inside a greenhouse like at True Garden, to optimize the crop yield per square foot, we use the 13 pots (52 plants) per tower model since towers cannot be affected by the wind factor.

On a rooftop, depending on the amount of wind/height of the building, we recommend the 7 pots/ (28 plants) Tower Garden®.

The microgreens tower follows the same guidelines in terms of size recommendations whether farming outdoors or inside a greenhouse/indoors with lights.

Please be aware of the following:

– The 13 pots (52 plants) model is the same height as its counterpart, the 26 pots ( 208 plants) microgreens tower!

– The 11 pots (44 plants) model is the same height as its counterpart, the 22 pots ( 176 plants) microgreens tower!

– The 9 pots (36 plants) model is the same height as its counterpart, the 18 pots ( 144 plants) microgreens tower!

– The 7 pots (28 plants) model is the same height as its counterpart, the 14 pots ( 112 plants) microgreens tower!

– The 5 pots (20 plants) model is the same height as its counterpart, the 10 pots ( 80 plants) microgreens tower!

The recommended size of the towers also depends on the crops being grown. For example, on a 13 pots tower, all 52 planting ports can be used to grow leafy greens or aromatic herbs. However, when growing eggplants, a shorter tower (9 pots/7pots) is better due to the weight of the fruit.

Some tower farmers use the 11 pots/44 plants outdoors 6 to 8 months out of the year (from spring to fall) and shorten the towers to 7 or 5 pots to use them with the LED light kits indoors in the winter.

Even indoors, like inside the Orlando convention center, a Tower Farm can thrive with towers configured with 11 pots (44 plants) with the appropriate artificial lights.

Within a school environment involving young children, we recommend the 5 pots (20 plants) which or the 7 pots ( 28 plants ). Both sizes can accommodate the LED light kit manufactured by Tower Garden®.

Of course, if we are talking about a Tower Farm for the cafeteria of a University like the one at UCLA, there is no size limitation.

In the educational market, the size of the towers depend on the age of the children, the facilities, and whether the towers are being used for educational purpose or to produce crops as a commercial Tower Farm (to feed the school).

Prior to selling a fully automated aeroponic Tower Farm system, we always consult with our customers to define the best tower size strategy for each project.

However, considering that Tower Garden aeroponic towers are modular in size and can be used indoors or outdoors, it opens a whole world of possibilities!

 

8. What is the Microgreens Tower by Tower Garden®?

The aeroponic Microgreens Tower by Tower Garden:

The Microgreens Tower by Tower Garden was originally designed to grow microgreens (of course!) but is widely used to grow “petite vegetables”and wheatgrass.

Considering that every crop that has been ever tested scientifically growing on a Tower Garden shows an increase of nutrient density, people using wheatgrass therapeutically should truly consider wheatgrass grown on a Microgreens Tower by Tower Garden for its superior nutrient values and increase in anti-oxidants properties.

Our Microgreens Towers should be renamed “Strawberry Towers”! In fact, recent tests rank these towers as the only viable aeroponic tower solution to grow strawberries commercially. If you’re thinking about growing strawberries, these are the towers to do so!

Whether using rockwool or coco coir, there is no need for a planting basket nor a clip to plant the seedlings thus facilitating the process and reducing labor.

Like with the regular towers, the Microgreens Tower come in sections/white planting pots as follows:

– 10 Pots (80 planting ports) – 1.4 m high.
– 14 Pots (112 planting ports) – 1.8 m high.
– 18 Pots (144 planting ports) – 2.1 m high.
– 22 Pots (176 planting ports) – 2.5 m high.
– 26 Pots (208 planting ports) – 2.9 m high.

Indoors, with the LED light kit designed by Tower Garden, we advise either of the two following Microgreens Tower models:

– 10 Pots (80 planting ports)
– 14 Pots (112 planting ports)

Outdoors, the maximum height is our Microgreens Tower featuring 22 Pots (176 planting ports) – 2.5 m high.

Within a CEA environment, in a climate controlled greenhouse, we advise using the maximum size/height : 26 Pots (208 planting ports) – 2.9 m high to optimize space.

Anyway, whether they are called ‘Microgreens Towers’ or whether they should be renamed ‘petite vegetable towers’, ‘
wheat grass towers’ or ‘strawberry towers’, these towers are all about performance! They are perfectly complementary to our regular towers.

When buying a new Tower Farm, we advise our new customers to consider allocating a certain percentage of Microgreens Towers within the total amount of towers ordered in the initial set up of the Tower Farm.

9. How much electricity does a commercial aeroponic tower use?

The commercial pumps are rated at 58 watts per hour, and a normal timer setting is 3 minutes on and 12 minutes off, so that is 4.8 hours per day of run time. So, 58w x 4.8 hrs = 278 watts per day per tower multiplied by your local electricity rates.

10. How much water does a commercial aeroponic tower use?

On average, about 1 gallon (3.79 liters) of water per day per Tower multiplied by your local water rates.

11. Do you provide nutrients and/or can I use my own?

In the world of hydroponic/aeroponic farming, aside from light, weather conditions and the quality of the water, everything relies on the excellence of the nutrients used to feed the plants.

We use a proprietary nutrient ionic mineral solution which has been specifically formulated for our towers. Unlike most all commercial fertilizers and all commercial hydroponic fertilizer blends, we are not adding fillers, dyes, nor binding agents. We simply blend raw pure mineral salts into 5 gallon pails.

This 100% natural nutrients mix is the most unique mineral-based nutrient solution ever formulated: contrary to most conventional hydroponic farming where a different nutrient mixture is needed for almost each crop, our aeroponic mineral nutrient solution can be used for all vegetables, herbs, fruits, and flowers grown on our towers.

Aside from the purity of the minerals used to make our nutrient mix, our nutrient solution’s uniqueness truly lays in the fact that only one single nutrient solution is needed to grow all crops! The same nutrient solution is used to grow leafy greens, aromatic herbs, flowers or strawberries!

Our mineral solution has been specially formulated to support Tower Farms’ towers highly oxygenated environment and to be used for the seedling process thus creating healthier plants.

We invite you to visit the beyond organic section of our website where we publish a scientific comparative study for crop yield and nutrient density. We have tested and compared over 160 different crops grown on our towers against the best equivalent produce resulting from organic farming (soil-based). The results are staggering! Our crop yield is 35 to 50% superior to soil-based organic farming. In all cases, we have an average ranging from 30% to 65% nutrient density increase. Our vegetables are better…much better: this is not an advertising slogan, but something that we prove scientifically!

Any other quality hydroponic nutrient formula can be used in a Tower Farm: many Tower Farm operators (including ourselves) have performed comparative tests in the past, but no one has ever found a better nutrient formula than Tower Garden’s proprietary Tower Farm nutrient solution when it comes to crop yield and quality.

12. How long does a set of nutrients last?

Each set of dry nutrients makes at least 10,000 gallons of finished solution at the full rate (example 1:200). The rate can be much lower (example 1:400) in warm season. Nutrients cost about $1.50 to $2 per tower per month depending on the crops grown and conditions (climate, outdoors vs. greenhouse etc.).

13. How does a Tower Farm automated irrigation system work?

In this video, Mr. Troy Albright from True Garden in Arizona demonstrates how the automated irrigation system of a Tower Farm works.

Our irrigation systems have been designed to supply the water and fertilizers to each tower on an as-needed basis regardless of the amount of towers involved. A tower growing strawberries will require more water and nutrients than a tower growing parsley. Our irrigation system automates the whole process regardless of the amount of towers involved.

True Garden in Arizona is the partner Tower Farm of Ibiza Farm in Spain.

A Tower Farm irrigation system entails the following:

– Container for nutrients A
– Container for nutrients B
– Gravity tank (size varies according to the amount of towers).
– Dosatron nutrition automatic dozing system (2 or 3 units depending on Tower Farm set up and the quality of the water).
– Manifolds (size varies according to Tower Farm configuration)
– Floaters for each tower
– Valves for each tower
– Modification of each tower (holes drilling to accommodate floaters and valves).
– Tubing to supply water and nutrients (size of tubing depends on the size of the Tower Farm and its configuration).

Example of an irrigation system set up outdoors:

14. How much space needs to be allocated per tower?

Although technically a tower uses less than 1 m², we advise to allow 2 m² (approximately 20 ft.² ) per tower: this includes enough space for the towers, the dosing station, the aisle spacing, and the propagation bench area.

15. Can a Tower Farm operate indoor with LED lights?

Tower Farms can be equipped with a state-of-the-art adjustable LED light kit manufactured by Tower Garden® to operate indoor.

Although such LED light kit was originally designed for 5 pots/ 20 plants towers, we use them for 7 pots/ 28 plants towers as it diffuses a sufficient light spectrum as shown in this video:

A Tower Farm could be used indoors year-round with lights… some farmers will grow seasonally outside with 11 pots/44 plants per tower and will size down their towers to 7 pots/28 plants and use them with lights indoor half of the year.

Please note that our LED light kit is not available yet for towers featuring 9/11/13 pots.

16. What are the specifications of our LED light grow kit?

– Maximum power consumption: 125 W

– Input voltage (USA models): 120 VAC 60 Hz

– Input voltage (European models): 230 VAC 50 Hz

– Working temperature: < 40° C / 104º F

– Luminous flux: 3400 LM X 4 pcs.

– Color temperature: 6000 K

17. Does Ibiza Farm & True Garden provide Tower Farm installation services?

We offer training services at Ibiza Farm on the island of Ibiza in Spain (outdoor farming) or at True Garden (our partner Tower Farm) in Mesa Arizona.

Small Tower Farms do not require training services in person. Tower Garden Ltd. provides a very comprehensive step-by-step instruction manual. Tower Garden technology is user-friendly and does not require previous experience. However, for large-scale Tower Farm projects involving commercial production, we strongly advise you to get a full training at True Garden, our partner Tower Farm in the USA.

18. Do we provide a suggested Tower Farm layout/blueprint?

We work closely with our clientele to customize solutions according to each Tower Farm project.

Just as an example, here below is a suggested layout for a farm featuring 300 towers in a 600 m² greenhouse.

19. What is the labor involved to run a Tower Farm?

Not only our aeroponic systems allow to save 95% water, 90% space while reducing drastically the risks of pests, a Tower Garden® Farm requires 90% less labor in comparison to soil-based farming: under greenhouse conditions, 1 individual can manage up to 150 towers (7800 plants).

20. Will I get training after I purchase my Tower Farm?
We offer training services at Ibiza Farm on the island of Ibiza in Spain (outdoor farming) or at True Garden (our partner Tower Farm) in Mesa Arizona.

We also offer onsite training and installation services across the globe.

Small Tower Farms do not require training services in person. Tower Garden Ltd. provides a very comprehensive step-by-step instruction manual. Tower Garden technology is user-friendly and does not require previous experience. However, for large-scale Tower Farm projects involving commercial production, we strongly advise you to get a full training at True Garden, our partner Tower Farm in the USA.

21. Are schools/charities/nonprofit organizations/associations eligible for discounts?

Tower Garden Ltd. features the same rates for everyone and does not grant discounts for charities nor schools.

22. Is the Tower Garden a hydroponic tower or an aeroponic tower?

Technically, aeroponics is a branch of hydroponics. Although unique, aeroponic farming relies on water and soluble nutrients as well like conventional hydroponics.
However, in conventional hydroponics, the roots of the plants grow in a substrate and are immersed at all times in a constant flow of water enhanced with insufflated oxygen + soluble fertilizers.

With aeroponics, the roots of the plants just hang in the air and are fed intermittently. Due to the fact that the roots have 100% oxygen availability, the delivery of nutrients to the plant is unparalleled. The feeding cycles do not exceed a cumulated total of 15 minutes per hour. The roots are therefore just dangling in the air at least 45 minutes per hour. That’s right! The roots are simply hanging in the air at least 75% of the time thriving in a very highly oxygenated environment without substrate, without water, without soil…this is what defines aeroponics!

Contrary to general perception, what defines aeroponics is not how the roots are being fed. In fact, many “hydroponic/aeroponic aficionados” are under the impression that with a “true aeroponic system”, the nutrient solution must be administrated to the roots by means of high pressure mist system, or even better, atomized, like with fogponic technology.

A HPA (High Pressure Aeroponics) system has the ability to produce droplets which are 50 µm or less in diameter. Think about it this way, the diameter of a human hair is 80 µm on average! Droplets which are 50 µm are the perfect size for optimum delivery and intake to the roots.

An LPA (Low Pressure Aeroponics) system produces regular size droplets.

However, whether HPA or LPA, the end results in terms of crop yield and nutrient density are the same. Aeroponics is not about low-pressure/high-pressure and the micron size of the droplets, it is about having the roots just hanging in the air without feeding cycles at least 45 minutes out of the hour. Aero stands for Air and this applies for HPA and LPA systems.

However, it is proven that due to the size of the droplets when 50 µm or less in diameter, an HPA system requires less water and less nutrients than an LPA system. In fact, 50 µm in diameter is the optimum size for root absorption and this is why less is required to produce the same results.

Scientific comparative tests have proven that crops grown on Tower Garden aeroponic systems feature a superior nutrient density and show an increase in antioxidant and phenolic values. Furthermore, aeroponics delivers on average 35% increase in crop yield and 40% water savings in comparison to conventional hydroponics.

In a commercial Tower Farm, the feeding cycles are programmed to be on for 3 minutes, and off for 12 minutes, 24 hours per day. In other terms, the system is only on 12 minutes per hour (4×3 minutes). The plants’ roots are just hanging in the air without water nor nutrients for 48 minutes per hour!

Whether speaking about the residential model of the Tower Garden, or whether referring to Tower Garden technology used in a commercial Tower Farm, these towers are truly aeroponic towers!

Now, someone could argue that a Tower Garden is also a hydroponic tower… Oh well, we will not start a discussion on hydroponics versus aeroponics… We will not debate on the subject of alleged “true aeroponics” being misconceived by the notion of HPA versus LPA: the quality of crops, whether grown on a HPA or a LPA system are the same and far superior to regular conventional hydroponics.

Tower Garden has been manufacturing hundreds of thousands of aeroponic towers for over one decade. Tower Garden technology was the first aeroponic tower on the market (back then named Future Growing). Tower Garden is the pioneer of aeroponic tower technology and commercial Tower Farm systems.
