ok bigsby thanks for your advice and ill go for the SOG and get the screen fitted sometime this week, as im growing in a tent im thinking i could ziptie each corner of the screen to a pole in each corner of the tent keeping it in place. The critical haze is a cross between barneys amnesia haze and a vigirous Critical mass male and is mostly sativa 60/40 meaning its likely to grow tall, so i planned on flipping tuesday (week 4) to avoid plants stretching too tall, what do you think? Ill check out your message now
