Growing Tomatoes in the Pacific Northwest can be a challenge, so I made this greenhouse to protect my plants from the rainy weather. Using a few simple materials from the hardware store this simple structure was done in about an hour. To get the full tutorial visit my blog @

sadly I have not "had" a garden for a few years...as I have been too busy with our cabin project and a gazillion other things about the house.
My greenhouse deflected many nasty Rocky Mountain hail storm with just the 4 mil. It was the UV that killed mine at end of the growing season.
Certainly a more stable house could be built for a more permanent year round use. A thicker 6ml plastic might be best and rebar's driven into the ground with the PVC pipes slipped over that to make it more storm resistant. To really make this structure solid, add more PVC pipes down the sides, drill holes through the connection points, and use a long bolt and screw to hold them together. If height is what your looking for, double up the PVC pipes and add a pipe connector to the middle.
@ Nancy R...if your using treated lumber, then container garden the plants. I don't use a stitch of that in my garden anywhere, even in the non- vegi beds, as they leach toxins. KMS has the right idea in that the synthetic products would be 'less' toxic and more durable but check into it to be sure.
@ Melissa W...I have hundreds of wild bunnies running around every spring! I did exactly what Marg C suggests to my vegi bed...as for the rest of the garden, I have a dog :)
