I have some D. spatulata 'Hong Kong' seeds from jimscott that I haven't sowed yet. I decided to sow 'em sometime this week since I have some extra room in my terrarium. Earlier, I had sowed some D. capensis 'Alba' in a pot in my terrarium, and some sprouted in a day, others in a few weeks. Though, I had no plastic bag on them. I know D. capensis and D. spatulata can be a bit of a weed and sprout anywhere, but is a plastic bag around the pot necessary? I mean, if the adult plant thrives there, the seeds should be able to sprout there too. So, should I just sprinkle the seeds onto some soil?
