l used to grow powdery mildew with my 1k hps, but since leds are such a game changer l figured ld let you in on a secret............. pm grows at 65rh the best. How do l know this? My lilocks , cucumbers and squash told me, actually my son just did. Sounds like last August in southern ontario. My temp is 90 my rh 80 lights on, feed homebrew co2 so exhaust only on for 2 hrs a day 1 hr before lights out to 1 hr after, 30% rh after flush. Fan only on half speed now. Second flower and no pm again. My rh with 1k hps was 65rh but 110degrees. Seems to like it. Sorry if lm wrong but had to share. Ive been growing pm longer than most of you have been growing for, my bad, lm old and ugly.
But besides the point greenhouses are humid as all hell 85rh or 90rh no pm there either. I can remember painting the greenhouse glass in june each year. Cuts the intensity of the sun, anybody who knows this that there is a sweet spot of when to paint.
So to conclude ill leave a few pics, 1 plant different strain all others wedding poop back left is cronic lm pretty sure. Put into flower as soon as they were big enough, 8 inches tall approx. Might do longer veg next time, maybe outdoor veg. Indoor flower. First almost homogoneous grow. Bagseed grower for years, was only way. Good genetics now, thinking of popping more. But l kind of want to keep them safe for now. I love my leds.
Mind this could be only area relevant but its always been an issue for me. If l knew this l would of found a way to raise what l was so poorly fighting.
The ramblings of an old man who wishes legalization never happened this way, but thats my bitch for another day. So my vpd is not perfect but smoke was damn close last time, might try flushing this time. No smoke is white, lol.
