I have been reading on orchids seed storage. Some species under specific methods can be stored for decades, while others no matter what, won't last more than 3 months.

I'm a bit lost and I'm looking for some guidance on the best methods to store my seeds for the longest possible period of time.

Right now I have my seeds in the fridge at 5ºC 50% with some silica gel bags inside a ziplock bag.

Any advice or recommended literature on this subject would be highly appreciated!

Thanks in advance.
