Loving this discussion....there are many different ways to follow a dream...it is fun to read what other people are doing.
Steve, I never thought of actually covering my greenhouse and using it in the summer, though I think the fabric to do so came with the kit. Not sure we two old folk could get the cover over it. How much does the shade cloth lower the temp? Maybe we will try that this summer and see how it actually works. I always wanted a "Summer House".
