Hello,
@rodakino.
Based on how farming works on Olympus & Survival, I’m going to assume it should be the same on Skyblock, that being you need to keep the chunk that the crops are in, loaded, so they can grow.
You can check chunks with
F3 +
G. I’m not 100% certain how Skyblock farming works, but I can’t imagine it being entirely different.
Hope this helps, and if it works differently, hopefully someone more knowledgeable on Skyblock can correct me. Have a nice day/night!
