Complete Tomato Feeding Kit: Tomato Fertilizer 4-18-38, Calcium Nitrate & Epsom Salt

The Greenway Complete Tomato Feeding Kit holds Tomato Fertilizer 4-18-38, Calcium Nitrate 15.5-0-0 and Epsom Salt for Plants in separate bags, sized to run out at about the same time. Together they supply nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and chelated micronutrients for a hydroponic or container tomato solution. The Starter kit (2 lb, 2 lb and 1 lb) makes about 250 to 300 gallons of finished solution. The Season kit (5 lb, 5 lb and 3 lb) makes about 730 to 900 gallons. The feeding chart follows the University of Florida IFAS hydroponic tomato formula built on a 4-18-38 premix, with a Standard recipe for water with 50 ppm calcium or more and a Soft water recipe for reverse osmosis, rain or soft tap water. Weigh each product per gallon by growth stage, and dissolve the Calcium Nitrate separately before combining. Packed and shipped from Madera, California.
