Canadian Xpress Wilt Guard is a great product to use as a Pythium preventative and potassium deficiency remedy. Potassium is vital for a plants' growth and increased levels of it can be needed during the flowering stages - depending on the genetics and maturity of your plants.
When your plants do not get enough Potassium they can become stressed and susceptible to diseases such as Pythium. Wilt Guard gives plants the strength to combat or avoid diseases during the often stressful flowering period by helping to regulate water loss. It further kills Pythium by stimulating your plant's immune system and allowing it to produce chemicals which kill the troublesome organism.
Wilt Guard is available in 1L and 5L bottles.
