The resultant product is an ultrapurified and extremely available form of phosphate infusing the surface of the roots with a large shot of phosphorus, resulting in root, foliage and stem formation.

CYCO Grow XL also encourages the uptake of iron, nitrogen and potassium to support the short, intense burst of growth that happens as a result of the application of CYCO Grow XL.
