Before switching to 12/12 should the girls go into a period of darkness in my tent for 24-36 hours? And should a heater be placed near the tent to ensure they don’t get too cold? Just trying to do everything to avoid hermied plants this time around!
I personally just switch it straight to the 12/12 but thats just me. If you want to do that you could and ull only need the heater if its getting below around 65f lights off
Welcome to the community ! I also just make the switch from 18/6 to12/12 usually 10 days before you see them start to flower after flip. Good luck
Same, I just switch straight to 12/12.
