How it works
- 1Check the live prices of supercompost, volcanic ash, and ultracompost.
- 2Buy a small test batch using two volcanic ash per bucket of supercompost.
- 3Combine full inventories at a bank and sell the finished buckets.
- 4Reinvest only after confirming that both inputs buy and the output sells.
Watch for
- A tiny cash stack creates extra Grand Exchange trips and lowers the practical return.
- This builds cash but does not advance a skill, quest, or transportation unlock.
