ok so this is a bunch of misinformation...
i assume youru talking about psilocybin mushroom spores.
you can store spores in the fridge for as long as you want and they don't need to be in a light proof container. don't buy syringes, buy prints and an inoculation loop. use agar cultures to create and isolate a rizomorphic strain (you will need a glove box, which is very easy to make)... do some reasearch on this, you will not regret it, you can also store a isolated strain in what they call slants, which you can make and store for indefinate amounts of time in the fridge... go to "the shroomery" it's a great fourum with lots of great people.
