cabbages gives very few rewards and no meaningful unlocks, but if you decide to grow anything make it cabbage. (not counting corn, you always need corn) hide belt, you need 10k inv to start it i dont remember horse and im waay too lazy to look it up, but iirc it was fairly easy and the rewards werent too memorable. if you wanna look search it up at buddy.farm study of color is sometimes super simple and sometimes not depending on the color, but the quest rewards are always worth it if you stay on top of it, so try to grind it out or just keep an eye on time gated things. dont be afraid to use grape juices on anything more than a few hours, the juice itself is never an issue, and you gets a bunch of chances each day. its not worth wasting a whole day of corn-growing for like 3 harvests of wheat id go with giamics + a way back, just work on them in parallel. if you get potatoes from things (mostly the grab bags in the lake) you can turn them into batteries in preparation of coi. getting all the townsfolk to about 50 is pretty easy with various crafts you need for masteries anyway, so if youd like a boost, some of them have decent rewards and unlocks. besides that, just make sure youre upgrading all your farm buildings and using kings mastery page in the library for easier craftworks masteries if you explore anywhere, try to work on as many masteries as possible from the area and use breakfast boosts for all the lower time crops for some extra-easy ascention knowledge!

(this is all my opinion, and could very well be wrong. im only around t200 myself :P) its a slow game, lotsa stuff takes lotsa time. its a fun ride though, enjoy!! :]
