Well I took the plunge and ordered my new greenhouse today. It is a Gothic style 14x24. with 8mm twin wall pollycarbonite sheets It will be here in 2 weeks. I have my fingers crossed that the weather will be nice enough to start putting it up soon after. Had I read the post on greenhouse feaver I may of had second thoughts. The kit includes heaters and fans. Farm Tech e-mailed me the instructions and they look like I need help. It says two people can put it together in a couple of days with simple tools. The instructions say you need a lift or a scaffold to put it up with and the list of tools is a mile long.
