Andi,
I have only been starting DL seeds for a couple of years now but I have learned from the best on what to do. I place my seeds in a ziplock bag and put in a few drops of water to keep seeds from drying out. Leave the seeds in fridge for a few weeks, they recommend at least three weeks. Then you have a couple of options, I place mine in another ziplock bag and add a mixture of 1 to 3 parts Hydrogen Peroxide and water til seeds are floating or covered with solution. I then place baggies in a warm place and check them every day. If the seeds are good they will produce a small white "thingy"(not a technical term, sorry). This is when I put the seeds in soil. I usually pick just the ones that have sprouted, some times I put all of the seeds from the baggie in soil. sprouting can take anywhwere from 1 day to as much as a couple of months or more. I also try to change the H2O2 and H2O solution every other day or so.Some people suggest to place seeds on a damp paper towel and fold towel over seeds and place in a baggie and store in a warm place and seeds will sprout for them. I think either way is fine and whatever works. Sometimes people just plant them in soil like any other seed. I do not know what germination rate they have but like I said whatever works.
hope this helps.
