One can go into any farm business that he's got no idea of and still do quite okay,
You can start a farm business without prior experience and still succeed in it, but you shouldn't start without acquiring knowledge because i dont see how possible it is to do quite okey in what you don't have idea of and also fail to acquire knowledge from expert who has been in that area of farm business. With zero knowledge you can only succeed in farm business if you are willing to learn and seek guildance from experience people who are doing the same business, experience can be gained along the way if you get started after gaining little knowlage since you don't actually need to know everything before starting, while proper guidance can help you avoid expensive mistakes in the process.
