OK, I've found some info for my question. According to Burpee customer service, the "block" of "organic concentrated seed starting mix" is coarse and "chunky" like the pellets -- not fine like the bagged material. (Although I like the bagged material for some things, also.) Menards carries the blocks, and they're on sale this week. Bought a block today, and I'll hydrate and expand part of the brick. Then post the results. The customer service agent said that he/she uses the blocks for seed starting for their own garden, and they are coarse like the pellets. Those pellets combined with the self-watering mat are just excellent. I've always had good success with them. So hopefully this will work equally well, but cheaper.
