Grow-N offers a highly concentrated nitrogen and calcium boost. It’s essentially a 4x stronger old school cal-mag (which had 2% nitrogen and 2% calcium). This product should never be overfed, but is incredibly effective at supplementing nitrogen/calcium.
Derived from bat guano, calcium nitrate, and magnesium nitrate.
Seedlings and Cuttings
No more than 1 TBS (15 ml) per 5 gallons or 1 ml per gallon.
Mature Vegetative Plants
No more than 1/2 tsp – 1 tsp (2 – 5 ml) per gallon.
Be careful – use sparingly. This is a concentrated product and nitrate nitrogen can encourage very fast growth (sometimes too fast).
