I have a space 15’x18’ to build a grow room, concrete floors and walls. Ordered vapor barrier for the ceiling. I have two Mars Hydro SP3000 LED lights, one Mars Hydro sp250 and three VIPARSPECTRA LED lights. I have two 3x5 tents and a MH 2x4. Ordered the AC Infinity CLOUDLINE T6, Quiet 6” Inline Duct Fan with Temperature Humidity Controller and carbon filter. What are your thoughts on the open ceiling with vapor barrier. Paint the ceiling? Walls and floor I was thinking of epoxy on both. What else should I be thinking about before I start framing. Also should I insulate the ceiling or is the vapor barrier enough. Room is heated and cooled.
