I don’t have air conditioning where my tents are, meaning with the hot weather we’ve had I have to partially unzip them when the lights are on and zip them up at lights off. The problem is I’m needing to change lights off timers to about an hour later, no way around it. So what would be the best way to do it, push in a 15 minute pin every few days or leave them in the dark for a couple days and change the timers all at once? All plants are at various stages of flower.
