Grimy guam detail

A Grimy guam is a herb that has not yet been cleaned to make a clean guam. Grimy guams may be grown from a guam seed with a Farming level of 9. Cleaning a grimy guam requires an Herblore level of 1 and gives 2.5 Herblore experience.

Clean guams are used to make Attack potions at level 1, Ranging potion at level 3, Guthix rests (requires 2 clean guams) at level 18, and Super fishing explosives at level 31. They are also a secondary ingredient for a Macaw, at level 41 Summoning. Grimy guams may also be obtained from the Sorceress's Garden minigame.

Cleaning grimy guam yields a profit/loss of 18 coins per herb.
