During the spring lockdown here in the UK, I set myself a challenge to build up a very profitable farm. I chose the default one whatever that is called, sorry too early for me lol. I built it up over the full three months of lockdown, and it makes over 200k gold a day. I utilised all aspects of farming, and making artisan goods.
Now, sadly the UK is back in lockdown till March so I set myself the same challenge again, this time using the 1.5 beach farm. With sprinklers banned over 98% of the farm, the best career path for this farm is rancher. My new file is animal based, I am primarily an animal farmer. All the animals on this farm are free range, which allows them to reach grass and pigs to dig truffles over a wider area than if they were fenced in. This has allowed me to kick start with truffles, a great source of income, and if you make truffle oil, they're extremely profitable. Pigs are one of the most profitable animals, but because they will not go outside digging truffles in winter or when it rains, it is best to supplement them with other animals and slimes too.
So really to me, it is not so much about what farm is best, it is about how you farm the land you have been given. Imagine it in real life, you're given a parcel of land, and you have to farm what will grow and live there and make best use of the land. So on a beach farm, your focus should be on raising animals, growing crops on the patch that does allow sprinklers, utilise the greenhouse and ginger island for crops and fruit trees. I use ginger island for my fruit trees, another extremely profitable venture. I turn most of my fresh produce into artisan goods, which doubles their value. Eggs into mayo, milk into cheese, truffles into truffle oil, wheat into beer, hops into pale ale, fruit and veg into pickles and jellies etc.
Wheat is a good all rounder for ranchers to grow, as it will drop hay as well as wheat. Make the wheat into beer or flour, sell the produce. Age beers in casks too, age them to iridium star, sell for lots of gold :)
Slimes can be very profitable if you know enough about their RGB values, which I am just learning thanks to a youtuber called Brannigan or something like that, who delved into slime science and how to raise slimes with the best profits.
Also if you're on a beach farm, you are surrounded by a massive resource, the sea!. Get crab pots all round your farm in the water,
So really all the farms have their up and down sides, it's up to you how you farm the land your grandpa left for you, however you choose to farm, you'll make him proud
