NPK Industries RAW Calcium/Mag - 10 lb

Water Soluble Calcium and Magnesium Support - 10 lb

Calcium and magnesium shortfalls can stall vegetative growth and flowering, and many fixes leave salt behind in the media. This supplement uses calcium nitrate and magnesium sulfate in a water soluble formulation with a ratio tuned to avoid a salty buildup. It contains 15% calcium and 3% magnesium.

The 10 lb unit suits regular indoor growers who dose often and want a stand-alone Cal/Mag on hand. Because dilution rates are low, a little goes a long way across many feedings.
