I have this Cali dream scrog going on for almost 2 months now in a 32"x32" tent. Have both intake and outtake fans. Intake is coming from attic so temperature with light on in around 75/lights off bout 65. Started first under cfl, then under 200w actual pull from wall cob led. When my plant got big enough for the 315w cmh grow light, I put it in. Growing in coco perlite mix- around 70/30 give or take. Using gh flora trio drain to waste schedule but not full strength with added calmag. Right now with light up as high as it will go right now I have a 41" gap from canopy to light, but light is set at about 26" and still getting great node spacing. Okay, so finally my ? is how much longer should I wait to flip to 12/12 schedule. Remember, I got between 18-22" space you play with
I would fill the screen. Why leave money on the table.
Just remember when you flip you will double the size so judge accordingly
I think you should fill the screen then flip u have enough space for some of the stretch without getting to close to lights.
