And no one elses wash bucket should look like that. Just making you feel better

Hahahaha. It does look awful, but it certainly gives me hope. Right now I'm thinking the first time I break open my dried and cured bud, I'm going to see lots of eggs, mites and cobwebs.
Best thing you can do is move the grow room to an area inside the house where the temperature and RH are better controlled.
I solved the humidity using an Aircon. And I have no other options in the house, except the spare flat. But I can only use that for short while. So it could potentially be the place where I move everything to while I clean my actual grow room. And my portable aircon should work just as well in the flat, i just need to find a way to get an airhole somewhere. But if I use the flat, I need to commit, I then also need to install an AC in there, and properly seal the windows and fix the floor etc. So committing to that is a big commitment. It would be pointless to move to the other room, only to have to do it again when I need to make the big changes.
All signs point to me finishing off all harvests before I leave the country in 3 months, and then taking everything out and installing the AC, fixing the windows, cleaning etc. So for now, I think I need to find a way to get through the drying and curing, and then do the same when the photos finish, and then stop until I can sort out the whole grow room.
