## Description

The Ultimate Hydroponics Growing Package! 1 pound Masterblend 1 pound Calcium Nitrate 1/2 pound Magnesium Sulfate Simply the best nutrient formula available for growing vegetables in a hydroponics system. Includes all nutrients needed for a soilless hydroponics system. The recipe for use in a hydroponic system is 12 grams Masterblend, 12 grams calcium nitrate, and 6 grams magnesium sulfate per 5 Gallons of water. This package includes enough nutrients for approx. 200 gallons of water. For example, if you have a 15 gallon reservoir, you could replace the nutrients every 2 weeks for 6 months!! For best results, Calcium Nitrate should be stored separately from the MasterBlend Fertilizer and Magnesium Sulfate (Epsom Salt) because they cause a chemical reaction in their concentrated form. For this reason, you should avoid pre-mixed formulas. This product is shipped with full instructions for use.
