Use for preventing wilting & eliminating Pythium. One of the major issues for a grower is that of root disease. The hydroponic environment provides the ideal conditions for your crop but ALSO provides the ideal environment for diseases that attack your crop. Half way into the flowering cycle the leaves have suddenly started to change color and they start to wilt. Why do these problems usually arise during the flowering period? The problem here is that plant roots virtually stop growing once flowering commences. They do manage to replace roots that die during the early stages but even that process slows down as the plant heads toward maturity. Wilt Guard is a specialized form of potassium which is very readily assimilated in large amounts. The mechanism by which these guard cells operate is potassium based osmotic pressure. By using Wilt Guard you are ensuring the best possible conditions for this process to take effect.
