Players can use a dose of compost potion on a bucket of compost to make it into supercompost, or use a dose on a full compost bin to obtain 15 buckets of supercompost instead. It can also be used on Big Compost Bin which turns all 30 buckets of compost into super with a single dose, thus doubling the potion's benefit. Players are advised to use these potions for their own compost bins instead of selling them away, as they will earn more by making buckets of supercompost, which in turn can be upgraded to ultracompost. Note that the player cannot add a dose of compost potion to compost bins containing a combination of normal compost and supercompost vegetation (in any combination).
