Hey guys its getting cold where I live and the lowest my tent has previously gotten was 64 degrees. This morning i woke up and it was 55 degrees in my tent! I have some 4 week old plants as well as some newly sprouted plants, so I was wondering..can cold temps stunt your plants ? I know cold temps can make some purp show but are there any negative effects?? I put in a heater to raise temps but im curious to know how cold weather effects your plants since I live in Texas this is the first time I've had this problem thanks guys
