I like to raise my own plants from seeds. Some seeds like tomatoes sprout really easily in a little portable plastic greenhouse on a windowsill, but others like capsicum and jalapenos take a lot more heat to get the seeds sprouted and then want lots of light.

Are there any reasonably priced grow mats around that can keep seeds around a selectable fixed temperature? Most seem to say "no thermostat, fixed at 20 degrees" or similar, but for capsicum/peppers you want more like 30 degrees. I'd rather have a thermostat based one, so it's not too cold and not cooking the seeds.

Also interested if there are any LED grow lights, or something that can be used for that. I only want them for the first few weeks seeds are raised in my shed, after that they go into my greenhouse. Everything on trademe/ebay seems expensive, even though LED strips and lights are typically really cheap. Heat mat is more important though, once they're up they can go into the greenhouse which gets decent light.
