The Grow provides ammoniacal nitrogen, potassium and calcium. Ammoniacal nitrogen is easily absorbed by plants. The result is fast growth over a short cycle. Very suitable for production crops. Grow is an ammonium nitrogen formula also providing calcium and potassium. Ammonium nitrogen is a highly active form of nitrogen immediately available and quickly assimilated by plant mechanisms. Beneficial for high yield and short cycle crops in accelerated growth environments. Super fast exaggerated succulent growth is characteristic of this blend. Excellent as a foliar spray for first aid to nitrogen deficient crops. Not recommended for low light conditions because elongation may result.
