i realize that it probably will not hold up to a new england winter. but i was thinking more along the lines of putting it up late winter or real early spring and then taking it back down when the hot weather arrives.

Way cool.  And free shipping.   I may get one of these myself.  My only concern is we get some pretty high gusty winds here at times.    

i agree, high winds & snow load would most likely cause some damage. the only thing to prevent snow damage would be to not use the greenhouse during the snow season. as for wind, i would imagine that there should be a way to anchor the frame to a base. maybe making a base out of 6x6 timbers anchored to the ground and then securing the greenhouse frame to the timbers....? i dunno, i'm just shooting from the hip here.....

I have seen them used successfully. IT depends on wind, snow and rain loads, but they do work.
