Actually I should have read reviews on transport, something I have not done for this command. 4 clamp in control 2 1250 2 1000 and arrived in 4 parcels "unsuitable" different. Result: 1 greenhouse broken seal on the top (he was missing the "protection" of black plastic used I think of wearing parts and replacement). Another or "protection" black plastic is absent too. Another piece or lower black plastic is broken. As stated in another client cartons are too big. 2 greenhouse joins literally crossed. After "moultes" orders from Amazon it was the first disappointment. But since Bessey made tough seal that limits greenhouse sensitive. I let you see the result image and you see if you want to try the adventure :)
