The seed box is an item that can store up to 2,147,483,647 seeds of six different types. It is purchased from Farmer Gricoller at the Tithe Farm for 250 points. This item cannot be used directly on a farming patch. You will have to empty the seeds to plant them.
Like Gricoller's can, the player can only own one seed box at a time. It is useful to bring for Slayer tasks and boss trips where the enemies drop a large variety of seeds commonly, such as Nechryaels, to save inventory space. Ultimate ironmen may find the seed box very useful, as managing inventory space is a key part of the game mode and seeds are valuable for Farming and Herblore.
