Guess thats what Ill do, maybe not the ducts tho lol.
I think ima keep running autos for a while too as theyre supposed to be more resistant. And maybe ill just give this plant to the friend who gave me the pm. Maybe that was his plan all along anyway.....
What is your day and night temps like in the grow space. Try to keep them at only 5 degrees different from one another. I had to setup an inkbird with a small space heater to keep my night temps up and I no longer pull air from outside since it’s filled with mold spores. I run a passive intake system so it just draws in the air from within my home instead of directly outside. But keeping the temps really close helped me the most. Good luck

I had PM for 3 straight grows, I finally got rid of it for good using Regalia and and AirROS machine from Sage Industries.

It`s been a year and a half and no PM.

I don't think you can use this after like 3 weeks into flower per the website. I'm looking for something for PM too. Also I didn't see any citric acid mentioned.
