mildew prevention

Fans for air movent/flow and trimming for the same reason. [edit] for wpm you have moisture where its forming, below 50% humidity you should not have moisture on the plant)[/edit]
One could try "trifecta crop control" which claims to be safe as well as organic. I have used it for bud rot control some years ago (really wet fall here), IF you want to spray something read up on it an make your own choice. Is anything sprayed on your buds really safe? (organic or not)

I have WPM all year round here in my outdoor garden. Nothing I can do about that than grow indoors. I use a humidifier during early veg and need a dehumidifier during flower. I know of no magic spray that you can put on flowers to stop it and still smoke the flowers. Everyone who grows outdoors around me has had total losses to WPM and mould the last three seasons.

It's easy to control indoors...Outdoors depends on your climate. It's too wet here.

WoW huge setup. No i grow very simply i don't ever use humidifier it's rather dry inside my little house. I've mostly grown outdoors all my life.
I've had to place wet towels and pots of water when i use to use wood heat. My main concern is keeping the heat up, for that i use a clamp on 54watt CFL with a reflector, same one i use for seedlings. Wish i could help more with the editing, hopefully someone with more tech brains will chime in.

You have 45-50% RH in your tent with no dehumidifier? That sounds like a dream.

Yes, I am in a 8x8x6.5 ft tent inside a 12x12 bedroom at the end of the house.

Howdy neighbor i'm down in Roseburg. Hell of a freeze you all had. Had my daughter staying with me for 7 days cause of power outage. For the last 4 days it's been like 65f crazy flux. Anyhoo I've not experienced PM issues at your level. I have central heating 70f in a less than 900sq ft home. My humidity in my tent is between 45-52% not the best and i will put a small clamp on CFL 50watt when and if the temp goes below 65f. I use a rotating fan on the outside of my tent but most folks have had a clip on inside i would highly recommend you use one. Are you growing in a tent? I'd use clorox wipes to wipe down the tent and or remove those plants from the room and spray some lysol kills mold an mildew. Hang in there others will chime in.

Looking for product or mix-it-yourself IPM recommendations for powdery mildew prevention during middle to late flower. I use neem oil for my veg leaves but that is not an option now that budlets have formed. Is there anything that 1) won't leave an unpleasant residue, and 2) actually works for PM
The humidity has been very high here and there is a lot of spore in the air outside. Inside the room, I have been policing my plants enough to catch individual spots of PM before they have a chance to spread. The environment has been remedied by a dehumidifier and AC (my electric bill is gonna be 💀). Now maintaining 74-75°F and 45-50% RH pretty much around the clock, with night being slightly cooler by a degree or two. Also the door no longer needs to be open to the rest of the house 24/7 so I'm hoping that cuts back on the spore traffic.

I'm not being overrun for now but I sure would like to add a second line of defense to the environment control. Also could someone tell me where to edit my signature, I can't find it in the menus.
