I've been using 1 tablespoon per cup of water. 3% h2o2. Using bottled Spring water which I am sure is treated with chlorine during processing. Good germination rate on viable seeds so far.
I was surprised that these 4 older seeds sprouted. They were probably collected in summer 2013, bagged, refrigerated, and then I bought them on the LA in the Fall 2013.
And yes they are soaking at room temp 76 degrees. The A/C is running all this time since I am still waiting on Winter temps to arrive in central FL. So it is dry and comfortable inside my home.
