Thanks again for all the prior advice. My Sarr seedling count is now 7 or 8 (out of ~25) so my yield isn't great, but for a first-time-ever attempt, I'll take it. The seeds were the ones Travis (Pyro) harvested and adnedarn sent out in packets; they're a mix from around 80 or so different Sarr species.
At what point should I put holes in the saran wrap (they have plenty of air in there) to start acclimating them to lower RH? They were in stratification in the fridge for 6 weeks, and have been under a strong fluorescent for about 4 weeks. If after 4 weeks there's still a good chance more will germinate, can anyone suggest a time line for this?
