hey fellow growers I just have like 2 questions i need an answer to. i know i know you guys hear that all the time but these are/should be pretty easy to get answered. my cab is one from walmart and is 57"high 21 1/4" wide and 14 3/4" deep. now the questions are what size fan (was thinkin 4 inch vortex) and what size light(was thinkin 250hps or 400 hps no more no less). jus seein what the experienced growers have to say. thats bot all the info i need. by the way i plan on getting the pyrex tube to make the DIY cooltube as i have yet to find a hood/ reflector to fit the cab. THANX TO ALL FOR YOUR HELP AND HAPPY GROWING AND SMOKING MeAn
If you are able to afford it over a 250, get the 400. Cooltube is great. I have a 400 in a pyrex bake-a-round. The 4"vortex is a good fan but are you using it to cool the room or the light? Or both?
