The patented vertical aeroponic Tower Garden® technology is made from some of the best food grade plastic available on earth. Our plastic is FDA food grade compliant and free of harmful components commonly found in today’s agriculture-grade plastics. Additionally, we designed the Tower Garden® product for decades of use!
Our plastic is several times thicker than almost all hydroponic products available on the market today. The plastic is also completely opaque, keeping all sunlight out (which naturally inhibits algae growth), and is UV stabilized for outdoor protection.
Most white plastics are not opaque and degrade quickly over time, as solar UV radiation tends to break plastic down from the inside out.
Seeds for the Tower Garden® are started in natural rock fiber seeding cubes. After germination, the cubes are placed in full light for a week or two, where they can develop into hardy seedlings ready to transplant into the Tower Garden®. The Tower Garden® has a 25 gallon reservoir at its base. This reservoir stores the Aeroponic Power-Gro ionic mineral nutrient solution. Inside the reservoir is a small, low wattage submersible pump. The pump draws the nutrient solution up through the center of each pot all the way to the top of the Tower Garden®, as illustrated (Note that the tower in the animation is about half as tall as a commercial tower). From there, the nutrient solution drips through a special device that evenly cascades the nutrient solution over the plant roots. On the journey down the tower, the nutrient solution feeds the plants’ roots and becomes highly oxygenated as gravity tumbles it back down to the reservoir. This process is continually repeated, providing fresh oxygen, water, and nutrients to the roots of the plants.
Because of the design of the Tower Garden® system, the crops grow faster than they would in soil, and have to be harvested on a regular basis! As shown here, aeroponic towers can be lined up in double rows for several hundred feet, creating extra-large plant sites of 120,000 to 250,000 plants per acre.
