I have used Bonide with great results. It is organic, Neem oil and water based. If the outbreak is not too bad run it on a 14 day cycle, but once every 7 days works fine. What size fan are you running? And at what speed? I found that as long as my ladies can handle it, I run my circulation fan pretty high. It keeps the spores from setlling and will also keep the pests from being able to hang out and cause damage. Not to mention it gives the plants a great workout.
laphter Reviewed by laphter on . Powedery Mildew, Too cold or too humid? I am getting sporadic mildew on random nugs. I can't tell if its too cold or too humid. My grow book says that anything under 76F will trigger mildew Someone at the grow shop told me because I run my lights at night, the early morning dew/humidity is hurting me. I have a 6 inch blower, blowing strait from outside to the low end of the room. He then recommended a filter or pantyhose to stop the water. I know that filters and pantyhose don't filter humidity, but the label on the on of the filter Rating: 5
