I am saying that his a/c being off for the night swaps temps in the room.leafminer said:You mean that he runs the lamps at night and has them off during the day? That's what I do. For the reason that day temps can go as high as 30C even at this time of year, but night temps are dropping as low as 12C. The lamps keep the grow room at about 25C at night which the plants love, and during the day they rest, the grow room would be as high as 38C if I ran the lamps in the day. Now, what you said last made little sense related to the first post about the grow room being so cold.
At night in the grow room (a/c off) his temps are 80-85 degrees
During day, lights on, a/c on, room is at 66 degrees
PM loves dark high humidity places ~80-90 degrees. BINGO
When lights go out so did all fans, a/c and exhaust (he is a power freak). His humidity skyrocketed as did his temps due to the warm garage during the NORMAL day and no a/c.
I told him to drop the temps when the light goes off by turning off exhaust with a timer, and leaving the a/c to cool on max; it will shut off w/no exhaust to pull out cold air and not cost much to run anyways as it is not cooling the light.
If you see PM patches on leaves, you are at level 2.CaliWizard said:i bought clones in sacramento ... have had them since the middle of september. when i got them i learned what PM was. at first it was only on one or two plants. i quickly got rid of them. but now it is STILL here and i have been spraying with Garden Safe Fungicide3 since the beginning. i spray daily and am contemplating tearing out my girls after reading this.
is there ANY way to get from LEVEL 1 to LEVEL 0 ?? i am definitely at level 1 because it is only on a few leaves so far everyday. but i am going to have to do something within a few days as i am worried of getting sick..
Most are at level 1 and just don't support the right conditions to germinate the PM spore.
I am happy to report that he is already seeing progress (3-4 days with cold temps). His growth has visibly slowed a little, but no new PM patches!!!!!!!
