I've never grown ginger from seeds, but Thompson & Morgans Seed Database says they are hard coat seeds, will need soaking, starting in hand hot water for at least 24 hr. Also if you have a pair of cuticle scissors or an xacto knife, you can nick the seed coat and soak. After their soak you want to sow them in a peat based potting mix no deeper than the depth of the seed but make sure they are covered. Temperature in the upper 70's to low 80's. I use a heating pad. Can take up to a month to germinate.
They probably will not bloom the first year as they need to make rhizomes.
Welcome. If you do a lot of growing from seed, here is a link to a copy of the Thompson & Morgan Seed Database. I adapted it to ms word so it can be printed on regular paper and bound. Click on the link and save the file.
