I was thinking of adding a duct to the top, where the fans are to vent that air out of the room. Just using the fans of the unit to push that air out, not adding another fan to suck it out.
I am thinking of just attaching that duct on the top and making that passive, using the fans of the panel. I am thinking I can use this LED panel and a 400 Watt HPS at the same time, so cooling would be best.
Like this guy did over at the CLW forums, right? If you need to remove heat, do it. In some cases it's worth it since too much heat can fuck with just about every aspect of a LED panel. Shit, a lot of budget panel owners should do stuff like this. Then again, (and I think a few people would agree with this statement), a quality diode doesn't need to run that hard to create useable light. And then again it is the panel designers choice if driving your diodes harder is cheaper than adding more diodes. Always decisions decisions decisions with LEDs.
I really wish CLW didn't do that "discount/post your grow on our forum" bullshit. I think it's one of the big reasons you don't see enough CLW grows around here.
I think the deal made people look around more and I guess some just bought it and said eff the discount so yeah good point. Now I don't know much about CLWs than the few I've seen at stores but do those top fans blow in or out? Usually on most panels they blow in for extra cooling. Could be a problem for what you want to do. Actually I don't think passive is going to cut it.
