Buy OSRS Huasca seed
The Huasca seed is a herb seed in Old School RuneScape. You can plant it in a herb patch at level 65 Farming. When the herb is fully grown, it gives grimy huasca. Players use huasca to make prayer regeneration potions.
The seed takes 80 minutes to grow, split into four stages of 20 minutes each. Each patch needs one seed and gives a yield of 3 or more herbs. Planting gives 86.5 Farming experience, and each harvest gives 110 experience. The plant does not regrow after harvest. Gardeners will not watch this patch for you, and a grown white lily will not protect it from disease.
Huasca seeds drop from The Hueycoatl, Amoxliatl, Mature custodian stalkers, Elder custodian stalkers, and the chest inside the Ruins of Tapoyauik. The seed appears on The Hueycoatl's Collection log. Drops from Amoxliatl or the custodian stalkers can also fill that log slot, but the chest in the Ruins of Tapoyauik does not.
This seed is a smart pick for players who want to train Farming and make prayer regeneration potions for long fights and bossing trips.
