Farmer

Tier          Exp needed     Plant & Harvest     Auto plant method 

Apprentice  200/400             20 / 40 about          34/67 or 101 total

-Note: (Method 1) There are two methods to farm, the normal / classic way of doing it are just plant and harvest then repeat then find your self a workbench and clean ? refine ? your harvests, but since you get a random number of harvests each plant its a little difficult to guess the exact number of plants you need so I just put 20 for proficient and 40 for mastered and that should get you there no problem.

-Note: (Method 2) Method two is the easy and consistent way to level up Farming. what is required is the specific tier of crop seed and water and you simply buy enough to max the crafting tier, for example apprentice takes 600 total exp to master and planting gives you 6 experience points so if you buy 100 seed / 100 water then you can simply click craft all and you will sit there and auto plant till maxed out. the pros to this is you can go watch you tube or do something else while your crafting and saves time, the con to this is it a bit more coin but its well worth it I say.
