My question is about when to flip to 12/12. I’m scrogging 3 plants. 2 of them are just into the screen and one of them is still a couple inches below but super bushy. My grow space is 32"x32" and I don’t want to outgrow my space. I’m reading that plants will double in size after the switch and I’m wondering should I fill the screen and then flip or flip now/soon to fill the screen while in preflower?
Edit, my tent is 63" tall and I still have about 30" above the screen to work with.
