When taking into consideration price, quality and need, this greenhouse package meets my expectations. I suggest using 4' T posts to anchor down the frame if a permanent structure is desired. Obviously, if you live in a high wind area anchor down this structure properly.
I used cedar fence planks to build 2 long raised beds inside the frame with a 12" walkway. This space is enough to produce roughly 50% of our family's vegetable needs.
The frame exceeded my expectations for rigidity. My plan is to use the greenhouse cover for the winter months and shade cloth to weather the summer months here in the desert SW.
Long story short, if you are contemplating purchasing but the inexpensive cost makes you anxious...go ahead and purchase. With some common sense modifications, this makes a fine greenhouse structure.
