For CBD hemp, I use a no-till transplanter for photo varieties and a Kinze corn planter for direct seeding auto flower varieties. Harvesting can be done by hand for small acreage or using mechanized hemp harvesting equipment. You can lose money in hemp or make several thousands of dollars an acre if you identify and grow for a reliable market. If you are serious about hemp, you need to be ALL in! Learn all you can, go to events, or sign up for the Hemp Innovators group where there is tons of practical info.
I hope this helps a bit!
