The Earthworm Farms in the surrounding urban areas were all small-scale operations, and their output of Earthworm Manure was low. Moreover, the long-distance shipping costs were very high.
If I really want to expand in the future, my shipping costs will multiply, and these farms won't be able to provide a sufficient supply. If I want to expand the Water Dyed Vine cultivation as I please, I might as well start my own Earthworm Farm. As long as it's big enough, I'll have all the Earthworm Manure I need! But there's still one question: is breeding earthworms expensive? If the cost is too high, it doesn't seem very economical to raise them myself.
