Giant seaweed detail.png

Giant seaweed are giant versions of seaweed. They can be used on a fire or range, which gives 6 soda ash.

Making 6 soda ash can however fail, resulting in only one soda ash. Players with 51 or higher Cooking will no longer fail, even on a fire. Note that Cooking gauntlets do not decrease the cooking fail chance, however the Hosidius Kitchen cooking range effect still applies.

Farming giant seaweed[edit | edit source]

Giant seaweed can be harvested from a seaweed patch at level 23 Farming after planting a seaweed spore. Planting gives 19 Farming experience and harvesting yields 21 experience for each giant seaweed picked. It takes approximately 40 minutes for it to fully grow. A minimum of three can be collected per patch, with the average amount harvested ranging between 15–34 (if ultracompost is used) depending on one's Farming level.

The magic secateurs do not increase yield of giant seaweed.[1]

Uses - Comparing Molten Glass yield and XP[edit | edit source]

When using soda ash and buckets of sand in a furnace the molten glass yield is 1.0 molten glass per soda ash and bucket of sand.

When using Superglass Make with soda ash and buckets of sand the molten glass yield is 1.3 molten glass per soda ash and bucket of sand.

When used in conjunction with the Superglass Make spell, giant seaweed similarly acts as six regular seaweed and gives 60 Crafting experience per seaweed when cast. The combination of two giant seaweed and 12 buckets of sand yields on average 1.45 molten glass per bucket of sand, while the combination of three giant seaweed and 18 buckets of sand yields an average of 1.6 glass per sand, although with the latter some of the glass will fall on the floor as it overflows from the inventory. If it is not picked up, it results in an average of 1.488 glass per sand. If players obtain the sand via mining sandstone, it is slightly more efficient to not pick up the excess despite the lower return due to how quickly the materials can be obtained.

The average Crafting experience per giant seaweed varies:

  • For an average of 1.45 glass per sand (two giant seaweed and 12 buckets of sand), each giant seaweed equals 538.5 experience when making lantern lenses or 669 experience when making empty light orbs;
  • For an average of 1.488 glass per sand (three giant seaweed and 18 buckets of sand without picking up the excess), each giant seaweed equals 551 experience when making lantern lenses or 685 experience when making empty light orbs;
  • For an average of 1.6 glass per sand (three giant seaweed and 18 buckets of sand and picking up the excess), each giant seaweed equals 588 experience when making lantern lenses or 732 experience when making empty light orbs.

These numbers include the experience from casting Superglass Make.
