I'm currently running 125w CFLs in a 2'x2'x5' growlab tent. I'm considering using a 150w HPS for flowering. How much heat do these things put off? Is it going to be way too hot for my tent? I have a 100CFM axial fan for exhaust with passive intake. Would I be able to move enough heat from the tent with this setup? I'm looking into a 4" inline fan with carbon scrubber for exhaust while flowering. Would that be the way to go if I got the 150w HPS? I need a flowering bulb for my CFL reflector and they are $80 for just a bulb. It's not much more for the 150HPS.
Any advice or suggestions would be awesome.
