homemade green house?

homemade green house?

Hi all, I planted my first veggie garden last year and had mixed results. I want to try some new things this year for better results. I'd like to start my seeds early and wonder about how to make a homemade green house outside? Most of the seeds I started indoors last year died when I moved them out doors. I have a large south facing deck that has plenty of room for starts, but I am worried about frost. Since I live in Seattle the growing season is kinda short so I want to get a jumps start on it. Additionally, I read that flowering veggies whose fruit grows above ground are best planted in a waxing moon and flowering veggies which grow underground (potatoes) are best planted in a waning moon. This was news to me - is it a myth?
