Sounds good, keep in mind they are winter growers, and want less than 12
hr. light/day.

This also sound very good! I haven't tried any smoke/water techinic,
but it is good that you are keeping them a bit cooler than room temperature

Oddly, these guys, it has been reported, need a warm/hot stratification.
The seed germinates in the fall with the onset of the cool, wet season. It
might take another year for your seed to come up. I sowed a pot of D.
stolonifera three years ago. Each fall some more of the seed germinates.
This year only one has come up. It was the second fall which showed the
highest rate of germination.
