I like it h202 seems to make sense to use for me. I heard I can put it in a spray bottle and spray buds in flower any one have any thoughts on this? Trying to kill mold right now with humidity and all this rain lately it's killin my crops .

I inherited white powdery mildew with a few plants gifted to me for my first grow. I tried numerous approaches, spraying with H202 was one of them. It worked ok for just hitting the occasional spot of mildew, but I found a milk foliar spray to be the ticket.

I mix 1 part organic 1% milk with 8or9 parts RO water, and spray them down good both tops and bottoms of all leaves and buds. This seems to keep them mold free for about two weeks before I would see any spots of mildew. It's best to try different ratios until it leaves a bit of white crusty residue on the leaves and then back off the milk just a bit. But it's really just about looks because I've had them covered with the crusties and they never missed a beat in growth so I know it didn't significantly impact photosynthesis.

How I know beyond doubt that it works is because the two clones from those plants went crazy in veg and since I was focused on those in flower did very little as far a thinning for air circulation. I was diligent however in doing the milk spray every two weeks. I put them in flower July 16 and have seen only 1 tiny spot of what I think was mildew starting.

I was planning to kill off these strains after this run but I may not need to now. I can build a good stock of oil from them before I move on to other strains.

I used mildew cure the first go round when I had a great deal of WPM. It works well and both it and H202 appear to kill it on contact, but the milk spray lasts longer and has no adverse effect on flowers.
