Biowave is a revolutionary patent pending machine that increases plant yields by an average of 20%. It operates by creating a subsonic harmonic wave that radiates out from the machine and makes plants breathe better. Biowave has been tested on the farm, in greenhouses, and in hydroponic growing facilities, and all tests confirm the gain in yield as well as a 55% gain in total dissolved solids. Many growers also have reported a huge reduction in insect loads. Current tests by Dr. Lynette Morgan in New Zealand have further confirmed the above results in greenhouse tomatoes. Biowave offers a three year limited warranty on parts and labor. Dimensions: 34.5" x 12" x 12". This item is non-returnable.
