I picked up some Burpee Cress (Berro Cresso) to try. The packet says days to harvest is between 15-35 days. I used this seed starting procedure, but poked extra holes in the rockwool like I’ve done with the arugula. The seeds germinated in about 24 hours and are looking healthy.
The seeds were planted July 22, 2015.

I’m going to close off this experiment and call it a success.
