This is the second greenhouse I ordered.  My husband assembled it. It provides more space and shelves to house more plants. The materials seem to be solid and sturdy enough. With the cooler temperature it would be perfect to grow more plants and vegetables. Last thing will be to put the plastic cover.  We shall also put the same bottom as the first one.  Shown in photos is the first greenhouse, slightly smaller, and we put an insulated bottom consisting of an inch of foam and fiber board. It has kept the greenhouse warm and more efficient at night, thus protecting the plants from the cold.  We've also installed a thermometer to allow better temperature control by adjusting zippered opening. We have it in a secure location, so we don't believe wind would be a factor.  However, if it does get windy, it may be a good idea to anchor it.
