I'm getting ready to start my first seeds, and being a newbie, I'm only going to try tomatoes this time around. I have a wonderful potting shed with large south-facing windows and a skylight, but no electricity. Is there any way I can rig that space up? I've been trying to find some kind of portable power device (https://tinyurl.com/nswbn8f) which could power a heat mat or a string of incandescent Christmas lights (for warmth, not light). Will that be sufficient, or do I also need an electric light? And since the shed is cold and a little drafty, will a heating mat provide enough warmth?
Another option is to set them up in front of a south-facing window in our uninsulated attic. I have power up there, so I could plug in a heat mat or Christmas lights for warmth...and they'd get a little warmth rising from the house. The same question applies -- can a south-facing window provide adequate light?
I'm trying to minimize my equipment costs and power usage. Any advice you can offer is appreciated!
Oh -- and I don't think I can do any of this inside the house because we have two plant-loving cats.
