Glass will cost you some 15% of your lumens. The thing I would do is tie them down so they can't get any higher. works like a charm
keylime Reviewed by keylime on . overgrowth Hi! I'm new here and I have a little problem with my grow. I have miscalculated the space I entered the flowering stage and my beautiful females have overgrown. So in order to avoid them touching the lamps ( warm white florescent) I thought to put a glass between them. Will it be OK? or the glass will interfere with the light? :jointsmile: Rating: 5
