We purchased the Juliana Premium 12.1 model with the 10mm panels. Shipping was quick and prompt, however upon arrival heavy damage was done to the boxes in... read complete review...
Construction of my Juliana Premium 9.9 greenhouse was pretty
straightforward. ...(The growing season is short in Alaska, and it was
pretty much a solo construction effort.) But it arrived complete and in
good shape, and with some features (like the continuous plastic
'mounting bead' strips to hold the polycarbonate panels) that I wasn't
aware of and appreciated...
I purchased the premium model...because I
was concerned about strength vs. snowload and windload. I decided based
on the cross-sections of the aluminum pieces I found illustrated on the
website. I am pleased with the model, the design and the components, but
I will still prop it up from the inside with a two-by-four just in
case. We do get lots of snow, and I'll be curious to see how much heat
accumulates in there come spring to melt it off and warm it up.
All-in-all I am satisfied with the greenhouse, the service I received
(you very quickly answered several questions I had during construction),
and now I am anxious to see if we can just get something to grow in
there! Thanks very much for your help.
