JB,
My luck came when I started using domed covered dishes. Like the take out kind with the clear lids. Also use root-tone to soak the seeds in. It seems they like just a little moisture and high humidly. The hard part comes when transplanting into their own pots. I hope to do this in late spring out side. Just one mess-up drying out and the whole project is done. I think that's where the lids come in at. Keeps it moist.
