First of do /jobs join farmer so you will become a farmer. Next do /warp farm to farm crops, there is a huge potato farm and a small pumpkin and melon farm. As well as some animals in the barn, you can milk the cows, shear the sheeps and collect the chicken eggs. You may sell the crops at /warp shop or near the entrance of the farm. Tho you only get 80% of how much its worth if you sell it to the farmer in the farm. I highly suggest you sell it to /warp shop
