Wilt Guard Use for preventing wilting & eliminating Pythium.There are a lot of challenges to be met when you grow a crop. This is especially so in the indoor garden as the crop is entirely dependent on you to provide it with all its requirements.One of the major issues 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.While disease attacking the aerial parts of the plants is always noticeable, those attacking the root systems do their destructive work in the dark. One day you are admiring your crop, the next day you are wondering what is wrong with it. Half way into the flowering cycle the leaves have suddenly started to change color and they start to wilt. All you can do is watch while your plants deteriorate and you end up with half the crop you were hoping for.
