Convert waterbed to heating pad

Joan Dupuis
19 years ago

for my greenhouse. I read a post about someone looking for a used waterbed heater to use as a heat mat. Can't remember where I saw it. Is there some way to set up an old waterbed mattress outside in my unheated greenhouse to be able to get them out there sooner. I do have electricity in it, but don't think I could heat enough with an electric heater and it would be too costly. Any suggestions.
