I currently have a bunch of sarr seeds stratifying in my fridge. They have only been in there about a month so far and I am wondering if they will possibly germinate while in there or only once they get light and warmer temps?

Light and warmer temps.

Also, some seeds need longer to stratify. My flavas are ready to go in 4 weeks but my purps and Judith Hindle took 9.

If they don’t germinate while in the fridge how did you know when exactly they were ready ?

I only know from experimentation. I would recommend 8 to 10 weeks for most seeds. Longer for older seeds. My own flava seeds are the only ones that I ever got to sprout at 4 to 6 weeks.

It isn't a matter of knowing "exactly". You shouldn't aim for just enough stratification to trigger germination; you should aim for a thorough stratification to ensure that the requirement is covered. Waiting a few extra weeks is "insurance".

For example: I have a batch of Sarracenia minor seeds in cold stratification outside. The weather here in eastern North Carolina cooled off in November and won't warm up until March. I could bring the pot inside to get a head start on germination, but if I time it wrong, then none of the seeds will sprout. No, thank you. I'd rather give them more stratification than necessary versus not enough.
