I live in a legal state...problem is, we've had a horrible summer for growing...mostly cold, wet and overcast. Guess you know that speeds up and encourages PM! Does or has anyone used a commercial grade vaporizer and sulfur prills? I currently have just 4 girls left to harvest, probably this weekend. I've used Serenade, H2O2 and water, potassium bicarbonate and dish soap, horticultural castile soap (Dr. Bronner's) baking soda...you name it, I've tried it! None has worked well. On to sulfur...can anyone tell me how often to use the system and how close to harvest is safe? I assume my window has closed for this year, but next year looms! This was my first outdoor grow, and I've learned a bunch! Decent setup all in all...frost free and lots of sun (when it comes out)! Able to push through to the harvest, but I cannot deal with this again. I would really appreciate comments from serious growers on this subject...I'm going to have to grow indoors this winter to make up for what I've lost to PM this year. Nothing drastic, but who wants PM in their smoke? Not I!! Thanks in advance for your help! Hope everyone had a great Crop-tober!!!!
