Dr. Zymes has a spray for pests and fungus control. Has anyone used it and can describe how they used it. I guess you just spray it on the plants if one has a problem. Would it/does it effect the quality of the end product?
Don't wait for problems. Fix the conditions that would allow them before they start.
There are growers here who swear by that product to prevent pest infestation.
For mold, humidity control is #1 priority.
