        Generally about one month or so. I think it probably depends on
temperature as to how quickly seed matures.

        Yes, for most Drosera you get a better seed set ie: more seed,
when cross pollinating, at least in my experience. However, D.capensis is
such a weed, that I wouldn't worry too much about it.

        If you plan on moving them outside, do it soon. You don't want to
move them from a nice warm windowsill to -25C, as they will shock and die.
The S.purpurea will survive -25, as long as it's protected (which it
sounds like the box will do). The other one, hard to say without knowing
it's parentage. If it's a hybrid, they tend to survive low temps better
than many of the species. If it's got some S.purpurea in it, it'll
probably suvive with no problem.

        Same here!
