Won't be using the leftovers for 6 months. I assume the freezer would be the best place for them. Any other suggestions?
If you have this thing for icecube put in there. When it frozen take it out and put it in another small box. That's whats my friend do. http://forum.grasscity.com/index.php?/topic/1249051-The-Journey-of-indoor-scrog---New-SuperKush-w/-pics-*Enjoy
Cool, dry, dark place such as a drawer. I wouldn't put them in the freezer. I have seeds from years ago that I just keep in a drawer and they germinate just fine.
6 months? No prob- just keep them cool, dark and dry! Seeds are meant to last through a long winter with no trouble! 6 years and you might have a problem! Granny
