For your first plant, all you need to do is get some very loose soil, mix it with like 50% potting mix to make sure it's not to much like clay but still very moist, then plant the seed about 1cm under the top of the soil and only water when the top of the soil drys out.
It's probebly best to grow a kinda 'test' plant first so you know what to expect when you grow your biggens.
