My dad finally said I might be able to build a greenhouse, and I need some help.
1. I am on a budget. does anyone know where to get plans for a cheap greenhouse (is it possible to use those words together)
2. as it gets cold in winter I will need some form of heater. are there any that don't use electricity (anyone heard of this stuff http://en.wikipedia.org/wiki/Quicklime)
3. anything else?
