Place 2-3 seeds as a trail into a small match box type add some sand paper shake this scarifies them, for 1-2 minutes,then to a glass of water, with a half teaspoon of bleach at 25c/77f, ... find that on top of your modem or pc, or back of your fridge, even on an external drive...ANYWHERE, as temp is important, just leave them warm and wait 7-14 days if you must.
See the real deal here is that most growers just get the most popular seeds at the time, other you and me fuck the system up by ordering up market or expensive seeds, that means they dry out over time, as the cheaper younger and more germy seeds get sold first, 'ours' more expensive again dry out over time, and making the failure percentage far higher, many seed banks know this, and many work it not to your favor either ...hang in there !
