Can you put your plants into veg after one day of 12/12??I accidentally left the timer on 12/12 in one of my tents I was supposed to flick it onto 18/6, If I revert it back to 18/16 quick after only one day of 12/12 will this do anything or just slow the veg process down?Plant. Other

Soundproof grow areaI made a countertop tent out of mylar and 2x2s. Any tips on what I can hang on the front to dampen the sound of fans and filters? Foam didn't do much so I broke it into smaller pieces to block off the noisy fans and pumps individually. I'd like to isolate the whole thing ideally.Week 3
