A friend of ours (research assistant) just gave me this catalog sent to her business. I haven't had a chance to compare prices, but I will say this, it sure gives me a LOT of ideas. They have a lot of stuff here, stuff I have never seen for sale at the usual locations. So, thought I'd share what looks to be a quality vendor.
Thanks, ganjagoddess. My husband went through some of the print catalog last night and says he's got ALL kinds of ideas, and for more than just the greenhouse we want to build, too.
