This is my semi-permanent solution. It's a pop-up greenhouse by Flowerhouse. It comes in its own little/big carrying pouch.
It's helpful to have two people put it together cause you have to work with the tension of the steel rods. It's kind of like putting up a big tent and it's fairly easy to do.
Here it is almost in place. Note the smaller one on the right. That was the original one I bought in 2005. You're supposed to be able to take it down and put it back in that pouch but try as we might, my husband and I were never able to even get close to getting it in the pouch. So it stayed up all year long (we don't really need it in the summer), and the year after that, and the year after that. But it has a limited lifespan. This year the plastic started to kind of decompose. So I struggled with the concept once again of whether to commit to a permanent greenhouse...
But when I stopped pulling in any money to our household, the decision was made for me. Another, and much cheaper solution, was just to get another pop-up greenhouse. This time I went for a larger one. And I also found out that what I really need is one that's twice that size! Lucky for me, if I can't make the commitment to a permanent greenhouse by next year, I can always buy another one this size and zip the two together.
