alright guys I have a question?..this morning I checked my temps in my grow box around 7:30am and it was 52 degrees F..my box is in an outside shed and it has been getting pretty cold at night now..as you can tell I am of course on 12/12 and it starts at 9:00pm till 9:00 am..what do you all recommend to get my temps up?.or should I be worried? I have read that between 70-80 F is the best..will cooler temps like 52 F be just as stressful as high temps?..they are looking so pretty and I hate for them to not grow some nice buds..what are your thoughts?...

here is my thoughts..I have one intake fan which pulls from outside, two exhaust fans, and one fan in the box..I already cut off one exhaust fan a few days ago..thought it might raise temps..but I'm not seeing a drastic change..I have a HPS light and during my summer grow I battled keeping cooler temps so I know the light puts of some heat, including the ballast..what I am thinking now is to cut off my intake fan which is pulling the cooler air in, and just let the one exhaust fan pull in air naturally? smart Idea or no?..another thought is to put a small heating pad in the grow box somewhere and connect it to my timer that runs my light..is this been done and safe? I don't want to burn my box or building down..I figure as long as it stays clear of water its a great possibility..but again I am not the most expert..any input will be very appreciated..thanks!

if you have the money you can always insulate the shed. they have the spray foam insulation which is pretty cheap i hear. you can also go to walmart and pick up a space heater or two to help raise the temps. ideally you want your temps to be in the low to mid 80's.

thanks doc!..my only problem is I am the only one that knows about the box and I am trying to keep it on the down low..I put the bubble insulation that reflects inside the box and the box is pretty much air tight, minus the intake and exhaust fans, plus I don't have the money to insulate my building as of now..any other possible suggestions? thanks for your fast response!

thanks doc! i stopped by walmart on the way home and bought me a small heater..it has temp settings so I think it will work out pretty good..I am going to try putting it in tonight and check my temps in the morning..I will set it for 70 to start out..do you think if I keep the temps constant around 70-80, even when the lights are off, that the buds will get bigger? I am only on like week 3 of flowering
