We are about 45 minutes south of Atlanta. Our greenhouse is aprox six feet wide and twelve feet long (I will measure it. One side has three feet deep planters. Every year, I have four tomato plants and one pepper, along with one cucumber vine that grows up strings and across the back. On the other side of the walkway in the ground, is a variety of lettuce, and a few bok chow and kale. This in itself provides a nice addition of fresh veggies all winter long, with the aid of one or two heaters. This would not work in grid down, but could give a good start in spring and produce aprox two months before tender plants can go outside. When I am really into gardening, I can start 250 plants in there and allow them to get about six to ten inches tall before putting them out. Some are bigger. I am posting this in the event there is someone out there thinking about a greenhouse. This gives you a few ideas of what you can do in that space. Do I wish I had a bigger one.....of course...I could pull more potted plants in during storms and winter over more, esp. peppers. Meanwhile, this is what we can afford to do and it is a major blessing. This is our third greenhouse. The others were in MO. They were larger and harder to heat. Did any of you plant cauliflower this fall? I did not, but with all the gloom and rain, it might have worked. Broccoli, cabbage and all greens did great through all this up and down weather. Nice to think about garden time again!
