Herb seed

Herb seeds refer to any seed used to grow herbs with the Farming skill. They can only be grown in herb patches.

Unlike allotment seeds, there is no way to protect herbs from disease. Players need to check on the herbs regularly and apply plant cure as required. However, there is a herb patch that cannot become diseased on top of the Troll Stronghold which can be used upon completion of the quest My Arm's Big Adventure.

Notes
 * 4x20 mins: the crop grows a little every 20 minutes. This happens 4 times until it is fully grown. Note that herbs do not need to be watered.
 * Profit assumes that the player is successful 75% of the time with a yield of 6 plants.
