1. Scoring with sandpaper in matchbox
2. Soaking in plain water for 24 hours
3. Napkins for approximately 24 hours
4. Transplant to rock wool plugs when roots are 1/4" long
Photo's taken 5/12/2014 - Had 2 rows of 4 each on rock wool slabs. Had to go out of town for a week and one side of the tubing got plugged so that it did not get any water. I lost 4 plants yet the others are doing well.
