Hydrogen peroxide for PM.

Due weather conditions perhaps closeness and proximity of buildings creating some stale air. After Hurricane Lee tropical storm came through. PM appeared,so i Got too looking what I can do. My Approach is dual step and don't know if it's anymore effective. As I didn't have hydrogen peroxide at the moment. I use soap Dawn, with a drop of oil. For first two applications. Lucky to have rain to let rain wash it off. Started to clear up, applied to two-part hydrogen peroxide to plant two days in a row. Seems to have ceased. Plant is still probably a couple weeks out. Any suggestions do I continue to battle this. I think the battle has been won. I guess update tomorrow

Looks good had same thing with mine last year bad probably from our pumpkin patch me touching it without washing my hands even changing clothes before checking on her,can get that way too. Just keep air flow around and prune a little to help with that. Dang bud rot will creep in. She looking good though

living in the uk, bud rot is inevitable in our climate, if its at all possable, we spend a lot of time cutting bud rot out. keep a close eye on her, cutting any rot out and you'll be fine

Milk does a good job if catching it early. Also makes the leaves kinda shiny and nice looking for a few days not that it's important,just saying.

yeah, i use milk/water on our melons and cucumbers at first sign of PM, works butifully.

Damn cucumber beetle one bite on a leaf infects the plant. There's hundreds of them stripped bastards flying around. Pot forrum talking cukes weed is in the Herb family anyway like parsley's cousin or one of em.

Here I go folks I have some evidence of hydrogen peroxide benefits. I know there's cons. Just trying to show that it's a great prevention tool or possibly, kick mold and it's ass and allow you to finish your season. I have some demonstration some pictures not sure exactly what they're telling me. I had Harvest most of my plant due to bad environment. This however was left to almost maturity. I would classify maturity, I also just Strip This Bud to do presentation and out of curiosity. Isolating this section of butt as it's no good for anything. Please comment if you use hydrogen peroxide and if it gives you any notifications that it's working. I even Browning drying out, excessive dry out during grow to indicate dying or killing mold. This is what I suspect

You've been out of grilling cannabis for, how many years. Sorry days why you on this site. There's no money in it so I can see you not doing it. I don't know how people are making it at $50 or under an ounce. Clearly not quality. Although you find some that appear to be quality.

Update I found only this while I was trimming the good buds. I had experiments with some earlier as well with the same result. It shows u that the bud was infected . With the trimmed beling crumble dry before any cure. The hydrogen peroxide I'm assuming is killing said area in bud. Discard of complete but when you find such.
