With SkyBlock being a game all about money, people try to find all the easy way for making easy coins, and composter happens to be one of the best passive mmm out there, treat just as another minion slot!
Before we begin, I recommend checking https://tinyurl.com/trueffsheet as it contains very useful resources that could help with this!
Now, I am assuming you have at least level 5 of all upgrades in the composter, though higher levels are always a plus. After that is met, use volta and box of seeds to run the composter as this is usually the best way to run it.
Make sure to check on the sheet that I linked if you want to squeeze every single coin for profit! Ff you find it hard reading the sheet, join the Discord server for help!
