Hi there... Love your design!!! How did you find the PVC being able to bear the weight of plants and soil? Did you have any issues with buckling or bowing? I'd really like to know as I am considering this for my yard... How did you end up attaching the shelves to the frame as well? Did they add sturdiness to it...? Finally were you able to dissassemble this when the season was over? Thanks very much....

So just to update everyone that sees this and wonders if it works. I planted a total of 72 tomato plants, 25 Pepper plants and various flowers for this spring planting season. I lost only 10 tomato plants, no pepper plants and only a few flower plants. This greenhouse worked great. I am very happy with the design.
