This grow formula additive includes nitrate and ammonium nitrogen. WATCH OUT!!! Use of this component will cause accelerated growth. If fast, expanded, succulent growth is what you want this is the stuff. Ammoniacal nitrogen is immediately available for plant uptake and assimilation and almost instant increased metabolism will be realized. Be prepared for proper pruning and plant support techniques because exaggerated growth can be overwhelming. High yield or short cycle crops can greatly benefit from ammonium because controlled accelerated growth systems can yield very high production and greatly increased profits. Also contains calcium as a very essential secondary nutrient. Works great as foliage spray for first aid to nitrogen deficient crops. Use with Micro-Base for a complete nutrient blend.
