Regarding Drosera I have had great success w using a mix of equal parts coir peat & LFS. Make sure not to cover seeds when you sow them. Keep temps & humidity relatively high... I gauge it with my hand. You can use ziplock bags / terrarium/ greenhouse/ I really like humidity domes. I like to use fluorescent or leds to illuminate the seeds. 3 - 4 weeks is average time for mine to sprout. D. Burmanii "tumbling waters" / D. Burmanii humpty Doo/. D tokaiensis & a few others just popped for me.
