Higher the temp say around 80 degrees will my humidity go down?

Assume the same amount of moisture in air... if air cools, the relative humidity rises since the cool air holds less moisture.

Also PM thrives in cooler temps.

Stay warm, I like my lights on at 83 canopy and my dark temps not drop below 80.

I use a heater in the winter to warm dark cycle as I have a large basement.

I run at night so in the summer I can just vent all day when the lights are off.

Oh crap yeah powder mold. Get some peroxide/ h2o2 in a spray bottle and spray the mold, it will kill it on contact(do not spray buds). (2 cap fulls , the rest water) get access to a dehumidifier or an a/c will reduce humidity also. If you think its out of control mold then get some Green Cure

Neem oil half strength, top and bottom, every week and you will be fine

I cleaned my room with bleach and sprayed peroxide/water solution on effected plants.
I also turned off my exhaust fan (just for the night) to see how temps change. Temps when I left the room last after cleaning and putting the plants back was 77f and 56% rh. I'm hoping when I wake up the temp is around 80 and humidity more in the low 50's. IF this is the case I will remove the booster fan from the light hood and use it just as an exhaust..not too cool the light.

I've used it 3-4 weeks into flower when I had pm issues. That was the only thing that got rid of it. Harvested just fine. Are you talking from experience or just talking.

I only talk from experience..I only give advice to things I've experienced myself and know for sure IM giving the correct advice. Im not saying you are wrong that you didnt cure the pm with neem , but I question if you cinged your new buds when spraying them with neem. You can spray with neem and avoid buds , but its kinda hard to do without overspray getting on the new buds. They can cinge and come back fully with my experience, but Id rather not take the chance of getting any neem in my buds. Peroxide and water in a spray bottle kills pm on contact.

It would probably be worth buying it for the last 4 weeks of flower. It last upto 45 days. I use a dehumidifier, cost me 80 quid. I would consider trying it ontop of using the dehumidifier. Sometimes it cuts off before i can get down there in the morning and dump it..I think this product would be worth a try for 10 quid

....Carbon filter fan used in conjunction with a dehumidifier can also help s great deal by both moving air, and trapping some mold spores that are in the atmosphere.

2 caps H2O2 per spray bottle 3% .... ? ? ? 24floz 32floz 1 gallon ???

Im quessing your using the smaller 24floz and a cap is about a teaspoon ? ? ? , either way the H2O2 concentration seems weak no ? ? ? , I hate applying water to a problem that was partly caused by water in the first place

I use H2O2 3% at 1 quater cup per 24floz on my seedlings of all types without issue

For powdery mildew on first sight I brush on 3% H2O2 to the affected areas, and then treat with standard preventative maintenance of neem, bicarb's, or copper sprays . this has always worked well for me in a humid area outside that is very prone to powdery mildew
