Here are some pictures of my new greenhouse which I just finished before our first freeze event. It is 36ft x 20ft and about 11 feet tall at the highest point. It cost $350 to build. I built this one just for growing hot peppers. I vent it by rolling up the plastic on that right side. I tack a 1x4 to the bottom of the plastic and will roll it up when it gets warmer and just before a freeze I drop the plastic down and tack it on both sides. I heat it by dripping water coming from the well. Now i need to put new ground cover on the right side and get the trees out of there. I already had one width of ground cover there and was growing about 60 pepper plants and just built it over the existing growing area. I will be able to grow around 270 pepper plants in this greenhouse and produce all year. Tom
