I usually do it like this.

1)Clear a spot for the plot.
2)Turn the soil and add water crystals, and some 4month time release fertilizer.as close to 20-20-20- as possable.
3)A few weeks later(mid April) I plant a bunch of seed directly into the ground
4)Care for them and water when needed
5)In august I remove the males and add some 2 month time realease bloom ferts
6)When ready I harvest the crop.

Good luck, and I will be willing to help you in any way possabe.
