Oh, there is a really important step that comes before the soaking. SCARIFYING the seeds will improve your germination success rate. The easiest method is to take an 8" x 10" sheet of 80 grit sandpaper, cut it down the middle long ways and roll it up into a tube with the grit facing in. Then I use packing tape to tape full lengh of the seam to keep it into a tube shape. I cut a piece of heavier weight cardboard and tape it securely over one of the open ends of the tube. You can use it successfully just like this but an extra step I use is to pour in a tablespoon of white or playground sand make sure it’s nice and dry.
Then drop your seed or seeds into the tube, put a finger over the open and and shake shake shake. I do it vigorously for probably at least 3 or so minutes. If the seeds still have the tiger stripe calyx stains on them you need to sand them some more.
I soak in a shot glass that I wash every time with H202 warm water. I rinse it out well then add one drop of peroxide to about 3/4 of a shot glass of tepid water and set the shot glass onto a seedling / seed heating pad. I leave it on there usually about 24 hours until I see the taproot starting to split the shell open. I remove it at that point and pour that water onto a folded up paper towel and put the seeds in and fold it over. I then put the paper towel into a zip-loc baggie and seal it up and put it back onto the coolest part of the heating pad. I check them periodically seeing how the taproot is coming along. When it’s 1/2" to 3/4" long I plant it into its final pot. I consider day one of the life of the plant to be when it’s standing and the cutting leaves are opened.
