I have only seen them at hydroponic stores (ironic, yes I know, since they are for soil!) and on-line at hydro/gardening stores, ebay etc.

I have noticed during early stages of seedling/clones growth and up through veg the square buckets are great to really pack them under the lamps. However, during flower you may need the space between plants so the expensive square buckets may be a moot point. An expensive moot point at that.
