AccelaFrame™ HD Greenhouse 12 x 20 x 9 ft. is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Great Seasonal Greenhouse! After many years of building seasonal greenhouses (wood, PVC to scaffolding frames) for my wife's tropical plants, I deceided to purchase the ShelterLogic - AccelaFrame HD Greenhouse 12' X 20' X 9'. It shows having 2 persons to assemeble and would be recommended, but it only took about 2 hours to errect it myself (30+ minutes to set the anchors in the good ole Texas soil). Overall this was fairly an easy project, is built of quality materials and looks much better than what I've built in the past. Great Seasonal Greenhouse.

Rated 5 out of 5 by from I like it! I bought this to replace a similar sized unit that was lost in hurricane Matthew. the frame assembled very quickly, one person 30 minutes. It did take another day 8 man (person) hours to finish the build but that is about 20 hours less than the first unit. The snap up frame seems really strong. I would like to see the instructions contain some written hints. For example: Don't anchor the frame to concrete until you get the support pieces in.

Rated 5 out of 5 by from Perfect I bought this greenhouse been growing with for the last couple of months and i gotta say it is worth every penny. Holds up to high winds with the anchors given. Cools down with easy lift ups and windows. I wanna get me a round top next. Not to mention shelter logics customers service was outstanding. Had an part missing and they got to me fast. Thanks for the awesome product.
