Those 4"inline fan's are quiet and work well.But the 6" model work's better with a carbon filter.I just started using the 6" for exhausting through the carbon filter & the 4"for fresh air intake.Work's great!Good luck & happy farming.
I'm using two 120mm fans, one as intake and one as exhaust but I still have a heat problem. I have read that it's most likely because my exhaust isnt powerful enough to be the dominate force. I have a sterilite 2 shelf cabinet and I'm fighting the heat
where are you shopping for bulbs? I googled "6500k cfl" and came up with 26 watt bulbs.
I bought my 105 watt's from http://www.1000bulbs.com/ they have every bulb you can think of.
