For now, I bought for 90 euros the greenhouse at Ebay. For the price I can not complain really. I have built up the GH alone, only when screwing the previously mounted in the garage items has helped my son. The GH comes in 2 boxes and I had only concerns What are you, especially after reading the reviews here. The guide is really to forget, but with a little thought, it has been going. I first mounted the 4 side parts in the garage and the frame. The framework was set in concrete and taken to the water. When setting up my son has kept short. If the parts are screwed and fixed to the frame, it is quite stable. The multiwall sheets I have all glued with silicone and then fixed with the brackets. This has 2 advantages: 1. the plates are already sitting firmly in the frame and 2. as durchbdas silicon panels are the top and bottom closed, can no bugs in the sheets and no moisture. Thus, the Platt longer remain clear. Overall, I spent 3 days to build required. Here and there would have to be reworked and a few screws have also been missing, but price performance is totally OK. So for the ambitious handyman or gardener that anything is possible.
