Hi Bumble I have just noticed this post and we do not actually sell a seed called Dageng? If you can let me know which seeds they actually are I will get some replacemants off to you. We have found the best way in the UK is a mix of 50/50 cactus compost and perlite and then to keep them at a constant 70 degrees. Every batch of seed we sell we test and if we dont get at least 70% we dont sell them. As Hetty says some seeds are just not viable but if you let me know I will get some replacements off to you.
