Hops give the 2nd best experience for leveling up your 耕種 skill in a single season (102 to 126 depending on how fast you grow it to maturity). It is only beaten out by a mature 上古水果 crop. A large amount of 啤酒花種子 can be a great way to quickly level up your 耕種 skill your first summer.
Selling 啤酒花種子 made from the 種子生產器 can be more profitable than selling the Hops directly, and also potentially generates 上古種子. Pale Ale and Pickled Hops are more profitable, but the 種子生產器 only takes 20 in-game minutes.
