m0useanswered grow question 7 months ago That's a smart thing to do, I use my tent as my dry room so I can't do that 100%. But one option is taking clones or starting new seeds and having them in a window just for the week or two while it is drying then transitioning into the tent setup. I'd also give the tent a good wipe down with some peroxide or bleach to to kill off anything that might be lingering. Always good to start fresh and clean.
I tried to do an auto grow in my tent along side a photoperiod grow and it went ok. The autos I did where going to be seed bearing plant and when I did pollinate them they did not grow much, this was all done before the photoperiods where mature or entering flower, the autos just chilled and made seeds, but I found I still ran out of room really fast and had to move them to a cardboard box to finish off under an old grow light. Good amount of seeds off of them for how small the plants where and it was my first reverseing attempt in making fem seed from an autoflower.
So give it a shot. just have a backup plan incase something goes a miss.
Good Luck!
