1st post, long time lurker 
anyway, I've got 2 plants growing in my shed, under a 250watt HPS light (old street lamp). They're in a 10'x4' partitioned room, with another divider making their room only 4'x4'. I'm towards the end of my grow, but the temperatures have been getting quite cold at night. I've got a heater in the room with them, but when its 18F outside, it struggles to keep up since the room isnt insolated very well (yet). I've been checking first thing in the morning at sun up, and they've been around 50-55 on a few occasions, and i'm worried its going to kill my plants. During they day the room sits at about 70F right now, but when spring/summer comes i'm going to need to air condition it. anyway, do you guys think the temperature is stunting my plants growth and is it going to kill it (should i get a 2nd heater?).. I think my plants look awesome for my first serious attempt, just gotta work on the stretching next time.. so here's some pics, feel free to comment on them and leave advice.. btw, how much longer do you guys think these buds have till harvest? I vegged for 30 days and i'm 36 days into flowering so far. I'm impatient as fuck, but only 'cuz my first attempt yielded some very whispy buds, and these are uber dense
