Space is a 4 foot long, 3 foot wide 9 foot Tall. Originally was gonna use this as veg room for outdoor, Turning it into flower room. 1000watt will be dimmed to 50-60% ( whatever the lowest setting is on my dimmable ballast) Going to have a 6in 430cfm fan in there The fan is going to go Carbon filter —-> hood ——>fan ——> out window. With a 8in passive intake at the bottom, The room where it’s going to be intaking from is a constant 73 degrees. My concern is even with venting out the hot air the inside temps are going to be 83+ So I guess my question is how much heat does a aircooled 1000 watt hps @ 50% dimmed produce? Thoughts?
