I have an FCE 6500 and am going to buy a similar size light for my second flower tent and I found a fairly new resale Thinkgrow model w which is 630w for 450, a one grow used fc 8000 for 700(800w), or a fresh fce 6500(730w) for around 520ish. Quality of light and yield potential is my priority...

My white widow plant has had a rough go of it and is flowering pretty loosely. Some of the newer sugar leaves(at least it looks like sugar leaves, it's covered in trichs) 37 days into flower are growing and looking exactly like bananas but they grow downwards like regular leaves or sideways...

I know Ill need to figure out a way too cool it down, and im wondering if running an exhaust fan triggered at 78 or whatever would be better than using an AC unit. One way I'm sucking the hot...

My fiancee and I discussed doing 12/12 with lights on from 9pm to 9am. Well I'm a freaking idiot and pulled the trigger to days ago to flip and my dumbass was too high and started lights on from 9am-9pm. My initial plan is to either walk it back by 30 min each day so tonight cut the lights at...
