Sprore syringes

How long do they last, i used one in march is it still good? kept in a dark cool place

I read a year as long as its stored properly.

is in the refrigerator considered proper? just curious cause i still have a few from april. thanks

Yup. A okay

Yea I heard fridge was a year but dark cool place was 3-5 months

spores last forever.. literally
probably came from space originally
if your real good you can germinate spores that are decades old and dried out, they just are not like seeds in any way
