Well I'm new to this, and i'll be growing my own medical marijuana from now on. Built my 8x13 grow room these last 2 weekends. The build of the room is completed, just got to setup the lights, hydroponics, fans, intake, and carbon filter exhaust. I've decided to go with 2 600watt HID lights over LED even though I do have 1 LED light right now. HID lights will be in tomorrow. I've decided to not use the Co2 right now until I get a handle on it all. I'll get some pictures uploaded tonight.
