Alright I have a sealed grow room except for cracks and what not that's about 9'x9' I have 2 600 watt lights running one in a tent and one outside the tent now the problem beings it's winter I can get by in the the 70's when it's about 20 out but anything above like 40 puts it over 80 in there I can't vent outside even tho I have access cause of smell cause it would come out the side of my porch I did it one day and thought they were blazing outside so I was looking at getting one of those portable a/c units does anyone know if they are they any good for grow rooms and worth the 200 or so dollars cause come summer I'm gonna have to take down one of my lights cause it will never work with both so if anyone can help me out it would mean a great deal thanks, mike -stayblazin
What are you doing for fresh air intake and exhaust? The idea of a sealed room is that you use an AC unit (not a portable unit) to bring fresh air in and to exhaust, not that you have no air at all which is what your room sounds like.
