May it be to achieve food security while reducing pollution and emissions related to transportation; or to cultivate the most powerful and clean medical cannabis possible, the practice of high pressure aeroponics offers the solution. To succeed, one must know how to master the quality of the mist first, then overcome the obstacles related to its development by making the technique free for all.

The benefits of aeroponics have been known for several decades but with the recent legalization of cannabis, we are looking again for the winning formula promised by this high-level no-soil technique. However, it is rather with the vision of feeding populations more effectively that it has been experienced for 100 years.

It is also the food and ecological challenges of our time that pushed us to put this technique into practice three years ago. Like many researchers before us, we have achieved impressive results in crop health, quality and productivity while reducing the use of water and fertilizer and completely eliminating the use of phytosanitary products. But the question quickly became: Why is this technique not more used in the world of agriculture today?

Overcoming several technical challenges, such as the clogging of misters, we found that some technical limitations may have hindered the large-scale application of aeroponics. But by hovering its complex past, we saw the socio-economic factors and business confusions that prevent it from taking off and becoming a viable solution for producers and the environment.

In Quebec, where we locally produce less than 20% of our fruits and vegetables and the use of pesticides is considered the greatest threat to our waterways, it is high time we share our progress and hope that these will help make aeroponics accessible to all.

1. The aeroponic solution

” According to AgriHouse, growers choosing to employ the aeroponics method can reduce water usage by 98 percent, fertilizer usage by 60 percent, and pesticide usage by 100 percent, all while maximizing their crop yields by 45 to 75 percent. […] These results essentially proved that aeroponically grown plants uptake more minerals and vitamins compared to other growing techniques ” – NASA Spinoff (2006)

” [The University of] Ho Chi Minh has successfully studied the aeroponic method of growing broccoli, tomatoes, potatoes, spinach, etc. The results obtained were at least twice as high as those of a normal planting and cultivation on the soil … Growth 2.5 times faster; save more than 70% on irrigation ” – Trung (2011)

” Aeroponics is a soilless method for producing pre basic potato seed. The method can produce higher yields (up to 10-times higher), more quickly, and at lesser cost than conventional growing methods ” – Otazú (2010)

Although there is still a lot of research to be done on aeroponics, its effectiveness and results are no longer to be proven. NASA studies on the subject in the 80s and 90s concluded that it was the most optimal culture technique to support all forms of plants; be it for the propagation of cuttings, high-value crops or even fruit trees. Several countries such as China, Vietnam, Russia and Peru have increased their potato production thanks to aeroponics.

The figures of Richard Stoner and NASA are impressive: 98% less water, 60% less fertilizer, 100% less pesticides (this also applies to herbicides and algicides) for 45 to 75% more production than modern conventional agriculture. This is a perfect solution for growers facing soil depletion and contamination, water shortages and phytosanitary addiction. This is even more an option to increase yields in agriculture while decreasing the pressure on territories.

Too good to be true? The explanation is simple: when you give a plant the optimal conditions by feeding it at will without forcing it, it is more productive, healthier and naturally resistant to diseases and pests. The plant does not spend all its energy building a huge root system because the nutrients are available and directly assimilated to the roots. Oxygen and CO₂ are also abundant at the root level, which prevents fungal diseases and helps growth. Also, with a mist of quality, the roots are stable so there is no damage related to stress or overproduction of roots due to bad anchoring.

2. Our experimental approach in practice

In 2017, after 19 years of hydroponics experience, Jean-François crossed the frontier he had long been contemplating: putting aeroponics into practice to grow fruits and vegetables all year long. Initially, we found that there was very little material and information available, and that experienced people were not only rare but long abandoned after a few failures. However, we persisted and discovered a unique world that we never want to do without anymore.

With limited resources, we went in search of the perfect mist from 50 to 70 microns, the ideal filtration system at 0 micron and the root chamber with optimal height. We are not from any research centers or universities. Our approach is practical at first and experimental by default because it seemed everything had to be done to realize this concept. We much prefer to work with the best fertilizers from Advanced Nutrients but have never received sponsorship and are not affiliated with any company. We have never received grants or investments either.

The only person we were originally accountable to was our 2-year-old daughter. Our wish was to feed her pesticides-free strawberries and food security for her generation’s future. In the face of our successes, we now want to push the concept further to make this technique accessible to all producers by reducing equipment costs and systems maintenance without compromising performance.

3. Limitations and challenges of large scale application

For 30 years, we have heard the same arguments about the technical limitations of aeroponics: maintenance, cost and availability of equipments as well the reliance on electricity and the learning curve. Yet many large-scale projects have sprung up around the world and even in some countries where resources are limited.

This led us to also observe the socio-economic factors that slowed down its development. In addition to the countries that kept secret military researches in a cold-war context, we’re also facing the agroindustrial giants selling fertilizers and chemicals, for whom aeroponics is a threat to their turnover.

To come back to the technical aspects, if the dependence on electricity and the learning curve are easily surmountable, the challenge of nozzles’ clogging is the one that posed the most problem. To obtain an ideal nutrient mist, around 50 microns according to NASA, the opening of the misting nozzle must be at its finest. In irrigation, such nozzles are used to control humidity levels and with pure water there is usually no problem. However, when we add 350 or even 500 ppm of minerals and / or organic nutrients we face a problem of clogging within 2 months sometimes even 2 weeks if there is organic matter in the solution.

Traditionally in the world of aeroponics, two strategies have been used to deal with this problem. For a university or military research center with big budgets, regularly replacing the nozzles is not a problem. However for a commercial producer, this is simply not an option considering that each mister costs between $5 and $15. Also, a need for maintenance in the middle of a season can be complicated or even catastrophic.

The other option is to widen the nozzle opening and work with low pressure systems. It lowers the costs considerably but instead of a well atomized mist we end up with a jet on the roots. This greatly reduces the benefits of aeroponics because the roots are in constant motion so stressed out, cut and overproductive.

High pressure aeroponics can also be damaging to the roots if there are pressure variations as the foggers turn on and the lines empty air in a jerky motion. We call this phenomenon “spitting on the roots”. To prevent this, the current technique consists in putting all irrigation lines under constant pressure using a pressure storage tank and several switches, electronic valves, relays and controllers. This is another expensive solution, especially since these valves often lose their effectiveness over time, which discourages many producers from adopting aeroponics.

It is hard to believe that a method more adapted to the needs of the producers had never been developed. We know that the fertilizer, pesticide, herbicide, fungicide, and algaecide industry has a lot to lose in an agrifood economy based on less polluting methods. Their lobbies have long been a drag on organic farming and aeroponics has the potential to be much more effective than organics in reducing inputs and increasing production. Today, organic agriculture is presented as the solution of the future, but 116 phytosanitary products are now allowed in organic farming and most organic fertilizer companies have either been bought by industry giants or are forced to buy their basic nutrients from the same giants.

On the other hand, as no-soil crops are not yet eligible for organic certification, producers do not have the motivation of added value to their products in order to develop them. In addition, the only commercially adopted hydroponic methods (NFT, DWC, Aquaponics) are quite greedy in water and fertilizer. A fact that does not mean anything in itself but put in context brings some lines of thought. An overview of the history of aeroponics helps put things in perspective.

4. Background and perspective of early aeroponics

First researches

Russian biologist Vladimir M. Artsikhovsky first studied bare-rooted plants and published the article “ On air plants ” in Experimental Agronomy in 1911. Several scientists in the 20^th century then used this method to advance their research on root diseases such as WA Carter, who published “A method of growing plants in water vapor to facilitate examination of roots” in Phytopathology in 1942; L. Klotz, who studied the roots of sick citrus and avocado trees spayed with a mist in 1944 and concluded that the method allows for healthier trees; and G. F. Trowel, who cultivated apple trees with root jets in 1952. The Dutch botanist Frits Warmolt Went named the method “Aeroponics” with which he cultivated coffee and tomatoes in 1957.

Developments during the cold war

The patents filed subsequently give a clue to the early commercial developments and it can be seen that aeroponics was also at the heart of the Cold War technological race.

In Israel in 1977, Isaac Nir patented the first complete system and method using compressed air for mist, styrofoam panels and pasteurization.

Some patents were signed by the Soviet Union in the early 1980s and mainly concern foggers but there is little information in English about them.

In the United States in 1983, Agrihouse (Steven Schorr and Richard Stoner) with the support of NASA patented the Genesis Machine , a device for cuttings with the first processor for automation and intermittent irrigation. In 1989, Quebec’s Karl F. Ehrlich patented a vertical design that improved the A-frame model.

In 1990, the All-Russian Research Institute of Agricultural Biotechnology (Moscow, RSFSR) began research on the use of aeroponics for reproduction of healthy virus-free seed potatoes. In 2000, a Candidate of Biological Sciences Yuri Tsaturovich Martirosyan for the first time developed the Universal Harvesting Plant “Urozhay-9000” for accelerated reproduction of healthy seed potatoes and other crops.

Meanwhile, China improved its potato tuber productivity from 11 tons / ha in 1991 to 17 tons / ha in 2000 thanks to aeroponics. In Spain, Italy and Korea several patents were also filed.

From 2006 and onward, the United States and NASA have run potato seed projects in Vietnam and Peru and are publishing their studies for the general public. The technology becomes known and the projects are multiplying in the world. Today, high-level aeroponics can be found in Ukraine, India, Japan and several African countries. The largest commercial farm is Aerofarms in New Jersey and its creators, Ed Harwood and Travis Martin, patented an aeroponic culture technology with jets and reusable fabric in 2014.

5. Business confusion

To add to the challenges that aeroponics must overcome in the popular mind, it must be mentioned that there is confusion in the market about the word itself. AeroGrow a company of Scotts-Miracle Gro affiliated with General Hydroponic and Monsanto / Bayer is the first to have marketed in 2004 a misuse of the term “Aeroponie” with its Aerogarden. In this device, the nutrient solution is at the bottom and the atomization is done by a vibrating air pump. The roots are quick to dive into the solution because the root chamber is shallow and they do not have access to a real aeroponic haze. It is actually a somewhat glorified DWC (Deep Water Culture) system.

Then Tower Garden in 2006 started using the term while its system is more a vertical NFT. The nutrient solution is injected through the top of the tower and trickles inside. Interestingly, their patent does not mention the term “aeroponics” but rather “hydroponic system”. On the other hand, their marketing is based on this word and for many people their product is the very definition of aeroponics.

In both cases, these models are simple to use and functional for individuals. However their performance does not compare to high pressure aeroponics and their use requires much more water and nutrients. They are therefore ineffective models for commercial application on a large scale.

Another technique called Dry Fog is sometimes marketed as a simpler, more reliable and more economical aeroponics. In order to atomize the nutritive solution, an ultrasonic machine is used, thus eliminating the nozzles. The fog which emerges therefrom has droplet sizes between 1 and 10 microns. NASA has already determined that the ideal droplet size is 50 microns to support long-term crops. In addition, it has often been shown that Dry Fog remains suspended in the air for too long, does not collide enough with the roots and eventually takes the place of oxygen in the culture chamber. The plants develop surprisingly fast at first, but soon find themselves dehydrated, nutrient deficient and suffocated.

6. Our results and vision

For our part, we have developed different solutions to the recurring problems of aeroponics while reducing the cost of equipment and without compromising on the quality of the mist. By using a filtration system and misters more suited to our needs, we were able to eliminate electronic valve equipments and the pressure tank. Our nozzles and filters do not need maintenance during at least 8 months even with organic fertilizers and when they do they are quickly rinsed and are reusable. This allows for complete seasons without worrying about the clogging of the misters.

With a pressure of 60 to 125 psi an atomization of 50 to 70 microns is obtained. The mist is delicate but assimilable and the roots remain perfectly stable even at the opening of the irrigation lines. In addition, the gravity quickly returns the droplets to the drainage which accelerates the drying and increases the oxygen levels in the chamber. Our pumps consume very little energy and can be supported by an emergency system consisting of solar panels or chargers and 12V batteries. We still chose to put a small cube of coconut around the most sensitive part of our plants which keeps their heart moist. This allows us to have a buffer of at least 4 hours before having to irrigate in case of technical problems, lack of electricity or maintenance.

Our results speak for themselves. We harvested multitudes of strawberries, cucumbers and peppers in the middle of winter, 184 g radishes, 200 g beets, wild blackberries with 17-foot-tall branches, hundreds of Espelette peppers on each plant, lettuce larger than our children, tobacco in 3 weeks and half a kilo Aji Charapita peppers on a plant of 17 months and her two cuttings. The three Charapita are now more than 7 feet tall and 20 feet square without showing any sign of weakness or discontent with their living environment. On the contrary, we are talking about a specie that remains a 3-foot bush in its natural state in Peru. All our crops have been documented and published online to remove any doubts.

Comparing our method to that of Agrihouse called True HPA^tm our benefits are in terms of maintenance and costs. Agrihouse’s systems, although they are the pioneers of the market, are still selling at astronomical prices as if they were made for space exploration budgets. The self-made HPA systems (DIY) currently found online are very similar to those at Agrihouse, at a much more reasonable cost, but still rely on electronic valves and the pressure build-up tank. We also find the same problems of clogging and if the mist is poorly calibrated we can quickly lose performance. Finally, compared to other cheap methods, our equipment is competitive but offers the true potential for high pressure aeroponic performance and efficiency.

From the beginning, we worked as a team and made a lot of sacrifices to make these projects a reality. I had to do a lot of research on vegetable crops and travel around the province and the Internet to find the right equipment. But it was Jean-François who unlocked the dead-end in which aeroponics was. Armed with his experiences in horticulture, hydroponics, mechanics and construction, he saw solutions differently where companies have spent years looking for the right path.

Tips for Winter Aeroponic Culture

Until we prepare our winter crops and open-source technology, here are some tips if you’re planning your own indoor space.

First, the choice of space requires different parameters. For a completely closed culture you must cover your walls, floors and ceiling with black & white polyethylene or silver Mylar paper to maximize your lighting and avoid mildew and other problems. Jean-François likes to build a wooden frame to minimize the holes in the walls, but there are also already silvered culture tents.

As light, we recommend a digital ballast equipped with a cooltube, blower, an HPS bulb 600W or 1000W (for flowering) and Metal Halide (for growth). Make sure that the digital ballast can fit all the bulbs you will need. The cooltube and blower are there to avoid overheating the grow room while redirecting this heat to the living space and thus save on the heating bill. With an installation as such you can add a charcoal filter if you grow cannabis and/or if you have pollen allergies.

Another option is to install the system in front of south-facing windows and add extra lighting, either Sunblaster T-5 or Sunblaster LED to extend the photoperiod. In this case make sure that all your components: pipes, tables and tanks are covered in white like polyethylene “Black & White” because the sun even in winter can overheat your nutrient solution very shortly.

For the aeroponic system you need: Pump, Filters, Misters, Roots Chamber, Tank, Plumbing, Drains, Plant Stand (3.5″ basket with clay balls and coconut or rockwool cube or neoprene), Sort period Cycle Timer (minimum 1 or 5 seconds on), Fertilizer (recommended Advanced Nutrients). Contact us for our self-assembly kits (DIY) of our technology already available including a pump, a filtration system and misters. For all hydroponic projects, you will also need some practical and essential tools: Reverse Osmosis, Computer and PH Probe, EC/PPM Pencil.

Thank you for having accompanied us so far in this presentation which is only the beginning. Jean-François reminds you that: “you have no right to make mistakes with your high value crops”. See you soon with your hands in the water and the roots in the air!

ORDER FRESH CHARAPITA NOW!

2 grams of Aji Charapita peppers were used for those 2 recipes. We are offering 30% off celebration discount and free shipping until 2019.

We are happy to introduce the Winter 2019 High Pressure Aeroponics (HPA) setup. We used the same 16 square foot indoor space as last year, but JF rebuilt it all from scratch making it more efficient and beautiful than ever. Here is how he made the new garden in 7 steps:

1. Prepare the space

JF started by pulling apart what was left of the old garden to redesign it. On the walls he put a first layer of black & white plastics and a second layer of mylar papers. To avoid piercing new holes in the walls and have more flexibility with our tables, he built a wooden frame and covered it with mylar papers as well.

2. Light and Blower

On the ceiling, he repositioned the blower and cooltube to make them both as high as possible. Last year, the blower and carbon filter were screwed to the ceiling and the cool tube attached right underneath. It was okay at first but by spring we had some peppers and beans growing above the light. Now with the wooden frame’s support, he could position everything right at the top without any holes in the ceiling. In the cooltube, we have THE 600W Hortilux Super HPS (best spectrum for flowering) and all its heat is pushed outside the garden into our apartment.

3. Bring in the tables and plants

During summer our HPA tables had been setup in a greenhouse outside. As it started freezing too quickly in the fall, we had to rush over 24-48h to bring the plants inside. So the three first steps were completed overnight and we installed an emergency reservoir before we could complete the other steps. The 6 months old Aji Charapita was at least 4 feet tall and 3 feet wide so it was quite a challenge to move it. Also, aeroponic plants having their roots hanging in the air, they usually get misted every 5-10 minutes. We had to be as fast as we could in that delicate step. The tables are now placed in L so the most mature Aji Charapita plant can get full light from a lower level than the others.

4. Door and equipments

Last year some parts of the garden were very difficult to access, even just getting inside was a hassle especially with my pregnant belly. Now, JF had the brilliant idea to build a solid door and wood panels openable with hinges. This solves a great deal of access problems for maintenance, electrical work, cleaning, pollination and harvesting.

On the other side of the door, he installed an old Coleman cooler as a more compact and food grade reservoir. In the reservoir he put the pump intake with a custom filter, an air pump and the PH probe on a floating raft made out of PVC leftovers. Just above in a metal box, he put the Aquatec 8800 booster pump (food grade and permanent magnet high pressure pump), the CycleStat-2 timer (set to mist 5 seconds every 7 minutes) and the Milwaukee PH controller/pump injector. In the garden he installed an air pump, extra fans, Sunblaster LEDs and neons.

5. Plumbering and misters

We started experimenting true High Pressure Aeroponics (HPA) in spring. On the summer setup we had Maxijet hoses rated for 125 psi and we had 55 psi pressure. But we noticed some leaks and deformations on the hose around the nozzles. It still worked but it needed tie wraps. So this time, JF built more rigid plumberings (quickconnect sharkbites) and we gained 3 psi (58 psi total) which does not sound like much but at this level it helps getting closer to the perfect mist droplets size.

We are also happy that all this R&D paid off in improving HPA technics. One of the biggest aeroponics critic is that the nozzles (also called foggers or misters) often clog. But with the technic that JF has been fine tuning for the last 8 months, NOT ANY NOZZLES has clogged even once. He recently cleaned some of them and I could take a photo of what 8 months of dirt look like while still working fine. This holds real potential for large scale Aeroponics as it could be possible to do a complete season without any maintenance on the misters.

6. Make deeper root chambers

Our peppers plants getting more mature, the roots were lacking space in the chamber. Because the tables were 8 inches deep, when the roots grew long enough to touch the bottom they formed a thick layer that would soak in stagnant water. The plant started to behave as if it was in an hybrid Aeroponics/NFT system, thus reducing its performance. So, JF extended the table’s root chambers with foodgrade styrofoam (the blue one) to 18 inches depth. The day after the change, the Aji Charapita’s roots switched back to a white color and for the first time we saw tiny fluffy rootlets appear.

7. Put it on wheels

The last but not least improvement of our new garden is that the whole bottom table is now on wheels. We can unfold it like a drawer allowing us to go work, harvest and do maintenance on the other side of our big plants. As for top table, its height is customable as it is hold by chains.

Conclusion

Now that all the mature plants are safe, we will be starting new seedlings. Last year, we were growing raddishes in 3 weeks and we can’t wait to see what effect HPA will have on those. Also, we still have a 4 square feet space available in there so maybe JF will come up with a new compact growing prototype.

For all of you indoor growers out there, happy season! Also if you have winter crops you want to sell check out our new partner RakeAround, an e-commerce platform for urban agriculture products.

Aeroponics has been put forward by NASA as one of the greatest ecological solution for the future of agriculture and food security. We feel blessed to be experimenting a technic with such high potentials.

In 2005, I was sitting in a Hubert Reeves conference in which he was asking: “What are we going to eat tomorrow?” In the last decade, issues like the loss of arable lands, desertification, food transportation and water pollution are a painful reality-check about our consumption wasteful ways.

Solutions come in many forms mostly by looking at ways to do more by using less, reusing more and wasting less. Aeroponics and vertical farming have been developed in this exact context.

 

Aeroponic vertical farming advantages

In the 1990’s, NASA researches proved High Pressure Aeroponics (HPA) was the most water and nutrient efficient growing technic that can sustain any types of plants, even trees. Since then, no better technic has been developed, it has only been improved with better yields and better results.

HPA is achieved with a high pressure pump (80-110 psi) and misting nozzles that gently give nutrient solutions to plants’ roots through an ideal of 50 microns droplets. It is a delicate technic that can easily go wrong but when done well, the results are uncomparable to other horticultural methods.

• Because nutrients are easily available, plants spend less energy on their root systems so they grow faster, are healthier and produce more yields
• “Aeroponics systems can reduce water usage by 98%, fertilizer usage by 60%, and pesticide usage by 100%” – NASA, 2007
• Vertical farming uses about 1/10 of the conventional agricultural space, therefore it releases pressure on lands and natural habitats
• Urban farming reduces food transportation as it is set up close to population density

A story that inspires

We see more and more urban, vertical and/or hydroponic projects rising in the USA, Canada, Japan and Europe. But the one company that is a true inspiration for us is AeroFarms in New Jersey.

Starting in 2004, they now successfully operate 9 aeroponic vertical farms, one of which is the largest indoor farm in the world. They compete with a highly subsidized agriculture and produce 390 times more per acre than field farming.

Our aeroponic journey so far

We have been experimenting low pressure aeroponics since two years. Before that I was an amateur gardener trying out aquaponics with mixed results. JF is the true master grower with 19 years of hydroponic experience. When we started in our 14 feet high solarium, aeroponics was JF’s last hydroponic frontier.

Since then, we cannot imagine going back as aeroponics is the only obvious choice for us. We are still mezmerized everyday by how fast our plants grow and how healthy they are. Last year, we had fun eating wild blackberries indoor with branches growing 17 feet in one winter. Also, we harvested more than 400 espelette peppers on 3 plants.

In our current setup, we are harvesting raddishes in 3 weeks, iceberg lettuces in 4-6 weeks and peppers since the plants were 2 months old.

We have achieved great results with only low pressure systems and now we cannot wait to try high pressure. We are soon expecting delivery on an Aquatec 8800 pump that will make it possible. So stay tuned for the next season HPA setup.

 

 

Update 08/04/2018: We have just received our Aquatec 8800 Booster pump for High Pressure Aeroponics. JF is already making a mess while doing testings and we are very exciting to share results very soon.
