Haven't tried it, but would be interested in the reults. I grow mine in dry shade, so it's well-behaved.

How long did you hang on to the pots?

Druse (Making More Plants) says temp reduction at night can be helpful, your seeds are getting that if you are putting outside, but he adds that germination may take from 30 to 180 days.

morz8 thanks for the info. I probably dumped the jug in June. This year I'll keep it longer and see. I didn't know it is one that takes so long.
