Perhaps I haven't seen all the responses about greenhouse shading so forgive me if I am repeating something someone else has mentioned. When we first built our recycled patio door greenhouse (12x15) in Michigan, it had a lovely view out the double-paned glass windows and I couldn't imagine covering the view or painting it away. So we had a winter without protection. That cost several hundred dollars for heating since we keep the temp around 50 degrees (lots of tropicals inside). Looking for protection and insulation, I read about bubble wrap and decided to try it. Using large bubble bubble wrap, I made panels of BW to fit the glass for each of the 25 patio doors using wide clear packing tape and then sprayed water on the window and placed the panel on the glass, pressing it into the window to adhere. That was four years ago now. The bubble wrap panels have, for the most part, stayed in place winter and summer (including the angled roof). If a panel comes loose, I either rewet the glass and push it back on or I could make another panel and replace it. It has out performed my expectations. BW did help stabilize our heating bills (electric) and while I miss the view out to the garden, I love the diffused light and cosiness of the inside. BW is cheap and light and easy to work with. I am really enjoying this set of discussions. We built our greenhouse in 2013 out of recycled double glass steel-clad patio doors (wood inside) and have loved it. Unfortunately, the wood inside is rotting away and we are thinking about a replacement this summer so reading about recommendations is very very useful and timely. Thanks so very much for all your comments and suggestions......Bonnie in Ann Arbor, Michigan On Sat, Jan 9, 2021 at 9:04 PM The Silent Seed via pbs < pbs@lists.pacificbulbsociety.net> wrote: > I have an AHA moment for you. > Glue tiny pieces of velcro on the vents - and affix velcro to the cut-outs > of cloth.
