Large Planter boxes

[daiwei]

I would like to build or buy some large planter boxes for a small outdoor garden.

I would like to have the planter boxes raise the plants off the ground level.

I would like to use Cellular PVC to build the boxes.

Could this be too expensive to build ? Are there Cellular PVC planter boxes for gardening that are sold in kits?

Any ideas?

Thanks

Cellular pvc is an extruded foamed product that mimics a pine board. It holds up excellantly to hard weathered conditions however it will not support itself. Build a pressure treated frame and cover with cell pvc and you'll have a good product.
