The high-quality resins used by Tower Garden are compliant with both U.S. Food and Drug Administration guidelines for food contact and European guidelines for Restriction of Hazardous Substances. Our resin material is also completely opaque — Keeping light out, inhibiting algae growth.
The PC/ABS which has been engineered for the manufacturing of Tower Garden has been successfully tested for chemical leaching all the way to the nanoparticle.
Although technically our proprietary PC/ABS is considered to be plastic, Tower Garden is the only soilless-food growing-system which has been approved for LEED projects (LEED: Leadership in Energy and Environmental Design). In fact, Tower Garden has been approved for LEED projects due to the durability of the material used to build the towers, in conjunction with the low energy and high crop yield of our technology.
When it comes to agriculture, whether organic or nonorganic, whether soil-based or soilless, nutrients are stored in plastic containers; Hoses used for irrigation systems are petroleum derived; Tractors are fuel powered; Crops are stored in plastic containers after harvests, etc. Furthermore, organic agriculture uses tons of plastic mulch made from wasteful plastic material (which quality is far inferior to the material used to make our towers).
Our PC/ABS proprietary formula is the safest plastic ever engineered for agricultural-related equipment.
Some Tower Farms have been using the same towers for the last 10 years. The longevity of a Tower Garden is unparalleled in the hydroponics- aeroponics industry. No one in our industry uses a PC/ABS material as safe, as thick, and as durable whether used indoors or outdoors.
