    Insulating your room should help keep temps up slightly, and it'll help with heat escaping.

    I have seen this, what you think

    2kw is a heavy load and costly to run, if you can knock it to half power and use a controller that would be ideal.

    How have you got your fans setup? Are they on a controller also?

    A thought for next winter: Do autos and run the lights 24/0.

    Insulate the grow room.Try get 100 ml kingspan on your walls. Wrap the pot in insulation too..remember it's the soil you need to keep warm first and foremost. Low temps will result in lower THC come harvest imho

    You don't say if you use a grow tent. If so consider buying a roll of the silver bubble wrap insulation from eBay and put it either over your tent or inside it, or both. This also stops condensation forming on the tent walls.

    I think it has 3 settings on this, I don’t have a controller so I could look at buying one this week and seeing if this helps.

    I am also going to buy some bed duvets to throw over the tent to help insulation I have managed to get the temps to 14c but would like to push 18/19 ideally

    My cellar is about 14'C, sometimes a bit lower. Either open cabs or open plan so no heaters used. They grew well enough. A 4'x4' scrog under 600w hps would average 18oz. (Photos, passive hydro.)

    Inkbird temp controller with a fan heater works wonders. Mines in shed and before getting this my temp would drop to 5c now it keeps it at 20c
