Gel Sack (Subnautica)
Overview
The Gel Sack is an edible flora species that can also be used to craft Aerogel. It is usually found attached to the walls of deep caves. It can be either picked up whole or harvested for Gel Sack Spores by using a Knife.
Key Data
- Category: Flora / Consumable / Raw Material
- Size: 1x1 Inventory Slot
- Bioreactor Energy: +245
- Food Value: +5
- Water Value: +4 H2O
- Rotting: Does not rot in inventory
Description
A Gel Sack gives one Spore per knife strike. Up to three Spores can be collected from a single Gel Sack in this way, with the Sack being destroyed by the third strike. Extracting Spores from a Gel Sack has no effect on its qualities as a raw material or food source if it is picked up.
Either item (the Gel Sack or the Spores) can be planted in an Exterior Growbed. It is a good idea to establish a growbed for gel sacks, as Aerogel is used in several high-end recipes and the plants are fairly rare outside of deep regions.
Gel Sacks are unique among edible flora species in that they do not rot while in the player's inventory, making them a viable food and water source for longer trips, but they do not provide much food or water individually. However, they only occupy a single spot in the player's inventory, allowing for many to be carried at once.
Appearance
The Gel Sack is hemispheric in shape, and has a blackish green surface covered with thick, twisted ridges. Randomly scattered across its surface are protruding, bioluminescent purple spots.

Data Bank Entry
These organic structures grow on cave walls. The purple sacks which arise from the surface contain a low-density gel laced with spores. These burst from time to time, floating towards the surface and attaching onto the next rock face they encounter.
While the gel sack is edible, its low-density renders it an invaluable advanced construction material.

Trivia
- The Gel Sack was originally called the Jelly Plant, and later the Spore Sack.
- In terms of space, Gel Sacks provide the most Food, H2O, and Energy in the Bioreactor of any Flora. For comparison, a single Marblemelon occupies a 2×2 space and provides +12 Food and +14 H2O and 420 Energy. Occupying the same amount of space, four Gel Sacks provide +20 Food and +16 H2O and 980 Energy.
- A good source of Gel Sacks used to be the Safe Shallows trench by the Aurora, but Gel Sacks there have since been removed from that location.
- Gel Sacks spawn on the underwater slopes of Mountain Island, including shallow waters near the beach.
- Gel Sacks are immune to brine.
- Gel Sacks are always found at the base of the giant Mushroom Tree in the Northwestern Mushroom Forest.
Bugs
- There is sometimes a bug where, upon eating a gel sack that has been in a grow bed, it will become a ghost item and, although it still takes up inventory space, cannot be interacted with. To solve this, save and reload your game, craft it into aerogel or die to reset your inventory to a previous stage.
- If a Gel Sack grown from a grow bed is knifed, it will split into four separate Gel Sacks that cannot be interacted with. Reload your game to fix this.
