It has become obvious to me that I'm going to have to build a proper greenhouse if I want to grow where I am living. Although I only moved about 75 miles from where I was, the temps are quite different as I am further north and higher. On the plus side, I am not going to have to try and deal with weeks of 100+ temps. However, the cold is a problem. Even now temps at night are in the 40s and 50s and I am not sure that they are going to get much warmer (although I have been told this is a cold year). Thee was a frost the middle of June and I anticipate that it will frost early in Sept. My 7 week old plants look more like 3-4 week plants and I believe it is the cold and wind. While I will not be able to construct something this year, I am hoping to get something erected early spring next year and am looking for ideas and input. I am thinking something in the 10 x 12-16' range. As I am renting, I would like to try and make it so that it could be removed and relocated if needed, but this is not essential. I am hoping to keep material costs under $2500. I have someone adept at construction who will do the framing up for me for free and I am pretty handy myself, so costs will be limited to materials. Looking for suggestions and ideas from anyone who grows or has grown in a greenhouse or anyone with greenhouse knowledge.
