The h202 is keeping the PM at the same level. I spray them with a 50 50 solution of 3% h202 every 4 days. The solution runs off now with no yellow or orange tinge to it. I think to be sure I will wash my harvest like it shows in that movie and then dry it. I am drawing up my grow room plans and the drywall room is going to have grates for air intake that will use a hepa house air filter (i will make slot to hold them). I have also ordered a dehumdifier to get my basement drier, something like 45% to 50% RH would be better. If the air is 60% RH the tent is too. I will make the environment not good for pm to grow and the problem will be solved. I think i might run 2 6 inch filters in the room too. I can turn the 2nd on if necessary to get more air flow.
I have a spare 6 inch filter that I will swap out after this grow (And I am cleaning that tent really well). I might do one more round in the tent but after that it will be the new room. I have a heater and will have the dehumdifier. If necessary i will get a little portable AC unit too.
PM would make me feel bad but....wow I am still learning tons of stuff. I understand better how RH can screw things up. I am grateful for the people on this site that said putting it in the cold room is a bad idea. It is 70% RH out there most days. I trimmed some larf off 4 weeks ago and put it on a cardboard box lid in the cold room. It is still damp and it smells like moldy hay. So that room would not have worked.
I also learned that plant density is not great for an enclosed space. They need room to breath. And shave their legs if you are dense in the space.
I have been pruning crap stuff off to free up some space and it is a lot better in the tent now.
Next grow will only be 2 plants so they have some room to grow.
And after that it is 4 plants at a time forever.
