When I grew them, I had no problem with germination.
Just sew them on sphagnum, keep moist, warm and well lit, and soon you'll have new plants. I had a whole forest of them. To think of it, I did the same thing with all the droserae, not only sub-t/and tropical ones, but also with temperate ones that need cold germination and they grew just fine. Just sew them and they'll grow.
Now I'm waiting for seeds to germinate as well, and I'm sticking to the old method.
