Mine are all enclosed inside the room. Works fine for me.
Sativagrowin Reviewed by Sativagrowin on . quick fan question! hi all, i just bought a new toy! 4inch rvk extractor fan with carbon filter and ducting! what i need to know is this: does it make any difference if the fan unit is inside the growing room or outside of the growing room? I want to be able to enclose my fan inside the closet so its not out on view for everyone to go 'whats that?'. I have enough ducting to run from filter to fan and then have another section for going out of the room. please tell me quick if anyone knows if it makes any Rating: 5
