I am no expert in fact i am just a beginner but i have being reading as much as i can before i start my 1st grow.

From what i understand when using flouros and cfls then ventilation isnt as much of a big deal compared to HID or HPS lights.

I think if you drill a few holes top and bottom and add a fan you should be ok.


But dont take my word on it let another members confirm this just in case i am wrong.
