My idea is to have a tiny green house and heat it with a hundred watt bulb. That would be about all I would probably be able to handle. LOL

Hubby could manage a full size green house. He’d probably want to put one of those fancy wood burning furnaces in though.LOL

you could always try heating the plants from underneath with a pad instead of heating from above with a bulb.

You’d just need an extension cord run out to your greenhouse to plug it in.
