I wonder if there is a very simple way to control one or two light bulbs in a box that are providing heat for my Tomato seed Propagator sitting on top ... i.e. I need the heat underneath...It would be wonderful if I could get a static 80 degrees ???..I am not an electrical person and I live in New Zealand which is a drawback in many ways for trying to find off the shelf items...I would be sincerely grateful for any tips on how I could do this.
I found this on the NZ online auction. Would this be what one requires?
