Keylime,

Thank you for your reply. Unfortunately, the room is in the garage up against a concrete filled cinder block retaining wall that has earth on the other side of it.
loopup2u Reviewed by loopup2u on . Please Help!! Question about Heat removal from a "Sealed" room OK, so I have this small area that I am turning into a grow room, the total area of the room will be around 250 cubic feet. The area that will be usable for the grow will be closer to 165 Cubic feet. The room will be completely sealed for the benefit of Co2 Enrichment via pressurized tank/regulator. As far as heat producing devices we are only talking about 1000 watt HPS, and probably 600 watts T5. A guess would place that pretty close to 5,000 BTU's when they are all on. What are my best Rating: 5
