Last grow I just did CFLs. Good enough. But I bought a 150W HPS for flower. I'm not sure if I'll hook it up though cause it'd take some doing. I have to jerry-rig the whole thing. I'll have to vent the heat through a hole I have to cut through the closet wall. But I'm wondering about the fan to push/pull the hot air through the ducting. Is it better to push the air (fan before ducting) or pull the air (fan after ducting). I ain't gonna cut a hole in the side of the house to duct outside. But I'm wondering about the fan to push/pull the hot air through the ducting. Is it better to push the air (fan before ducting) or pull the air (fan after ducting). I think a 4" fan will do nicely but I'm considering using the computer fan I have exhausting my cabinet now. It's pretty weak though and doesn't do much where it is now.
