I'm growing in a shed too. I use a little radiant oil heaters that tje suggested. This way gives you ultimate control of the temperature, and it's very cheap. My heater has a 600w/900w combo so it can reach up to 1500w', but that is way overkill. All i do is turn on the 600w setting, and put the nob at less than 1 (like .5) and it more than enough to make the plants happy, while probably using less than 50 watts.

My point is, you would have complete control with a heater with thermostat control without drawing all that power. The temps now only get to about 30 at night, but in the winter the low can get below 0. I don't know if this is the same for you, but it's a life savor for me. I'll probably have to bump the setting up to 2 or 3. Hope this helps.

Does it get hot where u r in the summer? If so how do you keep the shed from getting too hot?

what about the small ceramic type heaters from walmart? the ones im thinking of are less than a square foot, and have something called cool touch, so things that touch them dont get hot/catch fire.

also remember that all these heaters will list high wattage, but that is when the thing is on full blast which, depending on insulation, is most likely not needed. They usually turn on for a few minutes to maintain the temp, then turn off for a while. On medium or low setting(considering it is a small room i am guessing) im sure it would draw much less.

The best thing you can do is buy some "Great Stuff", its an expanding foam that seals cracks and holes. Use it to fill any and all cracks and holes in the hut. Where the roof meets the walls, walls to ground, and ALL holes and cracks even around windows. Then on the inside roll up some insulation that can also be had at home depot. Your main goal will not be generating heat but keeping it in. Conversely you can fill the walls with hay if you have access to them, but if they are bare just roll new insulation up in between the studs then put some drywall up over top(if you want to do it right). Dont forget the ceiling/attic. make sure you have that well insulated as well and any vents in it plugged.

I tyed the "heat emmiters" for added heat they dont worky verywell for how much watts they use.....i was using 4 of them in a 3.5 x 3.5 area and it only got 5 degress warmer in there and it was using like 400w of power just to get that extra 5 degrees hotter not worth it at all...

Unless I get an A/C, there would be no way I could grow in the shed in summers. It's been in the 50's here during the day, but we had a warmup last week and it was in the 70's. If I was to leave the door closed, it would get 100F in there without a doubt. This is my first grow, so I was lucky to start in the fall. The light adds about 20F degrees, so I'm blessed to have a natural cooling system

The flowering room is about 6 x 10. What size light are you going to be using?

Is your shed in a hidden place? There is no doubt the plants benefit from leaving the door open for a little sometimes, as all the air can be recycled with co2 rich air. Again, the benefits of growing in a shed, because you don't need a ventilation system as if you were growing in a basement or closet.

good idea, just make sure you conceal the light to the shed so no one outside can see it.
