How Many Phiddipus Regius Spiderlings Realistically Survive From a Fertile Sac?

[JonoPulchra]

Hi all,

I'm considering fertilising my Female P. Regius and just weighing up all the pros and cons for myself. I cannot seem to find an approximate answer to how many slings actually survive the hatching process. Does anyone have an approximate answer? As so i can think of pre-buying containers, live food ect. if I decide to fertiliser.

Thanks.

The numbers vary, but it can be 10, or 300, it really just depends on the species, and many other factors.

20-100/sac and she can make to 8/9Sacs.
However, i'd start off with a tray of 100.
