Buy RS3 Arbuck seed
The Arbuck seed is a herb seed in RuneScape 3. It comes from the island of Anachronia. You plant it in a herb patch to grow arbuck, and this needs level 77 Farming. It is a members-only item, and it stacks in your bank.
Planting the seed gives 150 Farming XP. Harvesting gives 205.6 XP. The plant takes 1 hour and 20 minutes to grow, in 4 stages of 20 minutes each. Each patch holds one seed and gives at least 3 herbs. Compost, supercompost, or ultracompost can raise the yield up to 6 harvest lives. While you pick herbs, you may get harmony moss at a rate of 1 in 60.
Arbuck seeds drop from Big Game Hunter creatures and slayer monsters on Anachronia, and from bosses like Raksha the Shadow Colossus. You can also put the seeds in a player-owned farm food trough to make Seedy mush or Variety mush for 17 XP each.
The seed can be taken apart in Invention. It gives 2.3 XP and usually gives Organic parts, with a small chance of Living components. This seed is a solid pick for players training Farming past level 77.
