Kit contains everything needed for plants to achieve greater health, productivity, size, yields, brix levels, nutrient density, and taste and after harvest sustainability. Kit will treat anywhere from 7 to 28 plants for the season, depending on the plant. Since yields are so much higher it takes fewer plants to feed an average family of 4, e.g., one tomato plant can produce several hundred tomatoes. Lets say one tomato plant produced 100 tomatoes. At average retail cost for a large tomato 1.50 x 100 = 150.00 dollars. At the show the kit was 70.00 and we paid the tax. That plant not only paid for the kit but made you 80.00. Yes, this kit will save you hundreds of dollars on your food bill.
