I agree if you have the tools and the skills, but the other greenhouse products are what saves time and money later. the actual fittings, plastic, nuts, bolts etc... not just the framing materials themselves. I know the plastic isn't cheap, but time is important, too. especially when the plastic deteriorates in less than a year if you use big box store plastic. you are spending a lot of time replacing it. AND recycle them off of craigslist,too. That is where most of my larger structures came from. We went and took them down and out them back up here.
