Seaweed detail.png

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 being around 15–32 (if super or ultracompost is used) depending on one's Farming level.

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

They can also be obtained by killing Lobstrosities.

Uses[edit | edit source]

When used on a fire, giant seaweed turns into six soda ash upon successfully cooking, rather than just one given by normal seaweed. You can however fail, resulting in only one Soda ash. Note that Cooking gauntlets DO NOT decrease the cooking fail chance, however the Hosidius Kitchen cooking range effect still applies.

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 12 buckets of sand and two giant seaweed yields on average 1.45 molten glass per bucket of sand. Players may also cast the spell with three giant seaweed and 18 buckets of sand which frequently gives more than 27 molten glass in return, dropping the excess on the ground. This is more efficient as it has a 1.6 glass per sand ratio and uses more materials each cast, making picking up the excess still faster than the 2+12 method.

When accounting for an average of 1.45 glass per sand, each giant seaweed equals 538.5 Crafting experience when making lantern lenses or 669 experience when making empty light orbs. When accounting for an average of 1.6 glass per sand, these values are 588 and 732, respectively. These numbers include the experience from casting Superglass Make.
