Happy New Year everyone!
I’ve noticed many of the CMH fixtures don’t have a proper sealed inline exhaust in the fixtures. Any ideas why? Am I missing something?
I found one that does (glass cover w/6" ducts), another similar but without the glass (no seal, no vacuum).
I realize a 315w CMH will put out less heat than say a 400w HPS, but will it not need direct inline venting? What if two lights are used? That would have to have some exhaust to keep temps in range. Would a general pull through a carbon filter to exhaust provide enough temperature reduction?
