Indoor How to maintain temps with LED's

[User K]

Yeah I use a reptil heat mat, seems to keep the bottom of the pots nice and warm, we have a small log burner and last night it kept the ambient temp of every room 21c, even in the tent

I run LEDs and find I do have to give some supplemental heat in the winter during lights out. I use variable speed controllers on my fans and am able to adjust my fan speed to keep the heat in during lights on to maintain the proper temperatures. But once the lights go out the temps do drop significantly. I'm using a small electric space heater I picked up for $18 at WalMart.

I was working with HPS and my temps were perfect but now have made the full switch to led. I was wondering how I'd combat low night time temps then I realised that I could stagger the light cycles of both my adult/nursery grow boxes to maintain an ambient room temp of around 21 degrees.

Obviously will only work if you have two grow tents
