Hmm, interesting. My environmental reader said that my nighttime is averaging 70 F and 51 RH. It seems that’s a little above what the article is saying causes the spores to grow but I’m still having issues. I raised both up a few numbers to see if that will help. CheersIt's the high % then massive drop that gets it rolling. Then they take over. Not my opinions... just what the research shows.
About to start flushing. Two weeks left. I’ve never used a sulphur burner. Will have to look into that. CheersOnce its growing you cant stop it with environment and spot spraying. You need to remove all infected leaves very carefully and burn sulphur for the rest of the grow if you dont want it to destroy the crop. You say you're in about week 7? How much time left before chop?
PM aint nothin to fuk with. Dont underestimate its ability to wipe out the entire crop. I've run many large grows and in your shoes, without question I'd be in there pulling anything with white on it and burning sulphur right away.

My controller tells me what the vpd is at all times. The issue is every cannabis site gives different opinions and graphs on vpd.Not 100% true, you need to focus on vpd
it’s about airflow and the optimism plants leafs, don’t keep shade bottom leafs and leafs that are yellow/dieing ( remove any leaf that does cover the buds, your growing buds not leafs )
LED’s you need to run the canopy based on the VPD vs a fixed humidity % score
Learn vpd ( most important part) https://getpulse.co/blog/vpd
don’t run your room based on fixed low humidity and trying to “ battle”the humidity that way, not only more electrical and waste . Look at all that cannabis outdoors ( yes some, it’s the airflow) you can have practically have 50%-100% aka non rain and th2e plants will be fine for days. I live in a area where in the last 3-4 weeks is just pure humidity and rain and I still get high % amount of bud. If you can seal your room enough to co2 and have the proper higher heat

Problem
In wk 6, the transformer blew outside my facility. Unfortunately I do not have anything to worn me of that. The plants were in 98% humidity for 20 hours. Water dripping off the walls. PM started a few days after.
The room is back to normal but the PM is still growing and I can’t seem to get rid of it. Day is 73-75 F with around 45 to 50 rh. Night is around 67- 70 with an average of 47 RH. Never going above 55 rh at night.
Why is the mold still growing? I have been spot spraying but it seems to continue to pop up . Cheers
