During the summer of 2013 the University of Mississippi studied the Tower
Garden, comparing yield with traditional growing. The results were published in
Evidence-Based Complementary and Alternative Medicine.
Dr. Suman Chandra (a world authority on plant physiology) conducted this study in Oxford, Mississippi. They found (very conservative
estimates):
-
Higher Quality of phytonutrients, minerals, etc.
Better than growing in soil in perfect conditions.
-
Yield up 30% across 8 different crops
-
Ease of gardening
-
Used approx. 10% of the space and water vs traditional
gardening methods
More research is planned.
