They are Cheryl but as you say they're also very rewarding especially when you have plants blooming in the middle of winter that shouldn't be only because they're in a greenhouse. I'm seriously thinking about getting a 16' x 32' solar pool cover to put on if the winter looks like it's going to be bad. I know it's supposed to be wet thanks to 'El Nino' and the cover could supplement my two propane heaters. They are my project, my wife hardly ever goes into them unless I want to show her something.
