I've had luck by getting small glass jars, filling them with tepid room temp water, and putting the seeds in, put them in a dark cabinet or cupboard, and leave them for 48-72 hours. Once the little nubbin is out, I poer the water out through a coffee filter, and nudge the seed very carefully into a small pot, (very small), plant in Ocean Garden or Happy Frog potting soil, moistened, then put the seed on top of the soil, spray it with water, and cover it barely, spray again, the spray will push it further in, put the pots on a seedling warming mat, and it takes up to 4 days to see the sprout. I keep it on the warming mat until there are the first established leaves showing. I transplant to a larger pot in 2 weeks, and do not need the warming pad. They need to be checked a couple of times a day to stay spritzed with water, because the warming mats will dry out the soil in a day. I've been doing this for 6 grow cycles now and it never fails. If the seeds dont sprout while in the water, I toss them after 72 hours because thats about all they can take being submerged. Works for me. My water is artesian well water, not chlorinated tap.
