light proofing shelf while allowing air flow
i have a walk-in closet grow room with a pair of shelves attached to the wall with standard metal strips and shelf brackets. i need to seal the shelf up so that it's light-proof and thus able to be used as a mother room while at the same time allowing air flow to keep the space cool. right now i have the shelves wrapped in black/white plastic with some vent holes cut but i need to greatly improve the ventilation. has anyone done something similar and if so, what did you do to seal out light but still allow air flow? thanks.
