I have a 4x4x7 tent that i have had great success in with cfls but i was going to upgrade to a 1000 watt amd i was just wondering if thats to much light and heat for such a small space
Right now I'm running a 600w in a cool tube in a small 3x3 tent. I haven't had any real issues with heat, but you will need to put some thought into you ventilation system and what kind of a hood you'll use. Feel free to check out my grow journal in the organics section or in my signature. I know it's a little smaller than what your talking about but should give you an idea.
I can help here. I was here a year ago. Biggest mistake I made was buying a 1000 watt unit. My temps were keep high so had to buy an ac. Now I'm wasting more money on powering it. Instead of going with a 1000 watt unit go LED. The price should be about the same (cool tube hps mh bulbs) around $200 led light for full cycle growing $290 (waiting for mine to come in now bought a mars II hydro.) It will use 1/10th of the power no heat takes up less room in your tent. In all honesty I do not think the extra bud I got off my second grow was worth the problems. In short I would not buy a 1000w light for a small room.
Thanks guys i think i might do another cfl and do a little research instead of jumping into it like i was gonna
$290 wont buy you a 1000w led maybea 350w total output.... No ones asked Whats you ambient temps during summer in your house What extraction have you got and have you got a cool tube or would you get one In order to get 1000w total led output youll need more like $600-700 and mars2 1600w and the mars2 400w hope this helps auto help page if you need help with autoflowers http://forum.grasscity.com/index.php?/topic/1294434-Need-help-with-autos?-Welcome new vote page sept please vote http://www.dutch-passion.nl/en/photovote/2014-09-03-autoultimate%C2%AE-loki_1752/
4x4 with coolish ambient temps and a cool tube should be able to take 1000w hps and good extraction needed If ya ambeient temps are high id get a dimmable one 400-1000w and adjust depending on temps if you can afford an led tho they are great love leds auto help page if you need help with autoflowers http://forum.grasscity.com/index.php?/topic/1294434-Need-help-with-autos?-Welcome new vote page sept please vote http://www.dutch-passion.nl/en/photovote/2014-09-03-autoultimate%C2%AE-loki_1752/
