yeah the little generator i bought via amazon from as a suggestion from another member, things puts off A SHIT TON of ozone lol.

i did shut down the exhaust while i ran it last night. The box instructions said that i can run the ozone for 1hr with no damage to plant life (but this thing really pours out the ozone so i dunno about that lol). and like you mentioned, stomata are closed at night, so i should be good to run it for 10min lights on/20min once lights off and vice versa before lights on, and start knocking out this damn PM! it's not bad by any means cause i've been combating, but it's making me put in a couple extra hours every 2 days for diagnosis, and then more time with foliar applications every 5-7 days.
my focus is the veg room for the potassium bicarbonate treatments (and plants <2wks in flower). i think i'm gonna blast the fuck outta the veg room with the ozone too (removing plants of course). for like 2hrs for sure. start doing it once a week. i'll pull out plants for foliar treatment, and i'll run the ozone in that room while i'm doing foliar in a different spot. and letting them air dry before going back under the lights.
yes the spore spreading... damn those conidiophores!!!!!!!! now instead of wiping leafs, i'm just cutting them where the petiole meets the main stalk. there's plenty of leaves in the canopy and clearly they need more airflow cause mildew is only showing in windless places it seems to me. i'm gonna be a couple more fans today and get like 4-5 of them rocking in that bitch.
thanks for the tip. i'm gonna check out the pile today once it warms up. supposed to hit 50...
