I am going this morning to visit with a lady who is one of the suppliers for a large nursery in the city. She has 4 green houses. I will get to see first hand how to start plants from seeds, what's the best soil, how much water, fertilizer, light, heat etc. I also have a lot of questions regarding starting a green house. I have the frame but I want her opinion on what she would use to cover it. She also has a cold frame and I am looking forward to seeing how she constructed hers. We are eating so many different types of lettuce and spinach now that I want to be able to grow greens during the winter months.

Post my info later.
