Hey Detroitfish,

Grodan makes a item called a "macro-plug" that is round and has a slit in it for your cuttings. You can root your cuttings in these, in plastic trays on your heat mat. These macro plugs fit into the pre-drilled hole of a delta block or hugo block perfectly...that's what they where made for.

They make the whole process easier.
