put them in a tray or box,its good to store them, in a dark cool place.dont let ,any water get to them or any hot tempeture .it can cause moisture and will cause the seed to germinate,a simple drop or two can germinate a seed or two if bunched together
gqone is right. dark and cool space with no moisture.
I put mine in a camera film container with a packet of silica (it prevent moisture in the container) you can find em in a lot of electronic equipment boxes, etc. Stick up in a cabinet. I had one germ. after 5 or 6 yrs. can't remember. Took for ever to crack open though.
I heard freezers before. It killed mine when I tried it.
