Aerogel is an advanced crafting material in Subnautica that serves as a vital component for building high-tier machinery and modules. Crafting this lightweight substance allows players to progress deeper into Planet 4546B by unlocking essential equipment upgrades. Understanding where to locate its raw ingredients will save time and ensure a smoother survival experience.

Required Ingredients for Crafting Aerogel

To fabricate Aerogel, you need two main resources: one Gel Sack and one Rububy. Both materials must be brought to a Fabricator to combine them into a single unit of Aerogel. Gathering these components requires exploring specific biomes that contain deep waters.

Gel Sacks are organic flora recognizable by their dark, purple-spotted appearance on the seabed. Rubies are bright red gemstones found adhering to rock walls and cave formations in mid-to-deep zones.

Where to Find Gel Sacks

Gel Sacks can be harvested in several dangerous biomes, including the Sparse Reef, Mushroom Forest, and Grand Reef. Striking a Gel Sack with a knife yields seeds, allowing you to cultivate them at your base using an Exterior Growbed. Harvesting the plant directly without hitting it gives you the intact item needed for crafting.

Cultivating Gel Sacks near your habitats ensures a continuous supply of this vital organic component. This farming method saves you from making frequent risky trips into deeper ocean trenches later in the game.

Locating Ruby Deposits across Biomes

Rubies are primarily located in deeper environments such as the Sea Treader's Path, Grand Reef, and Blood Kelp Zone. Searching along cliff walls and thermal vents usually yields several nodes of this precious gemstone. Equipping a Seamoth with depth upgrades makes collecting Rubies much safer and more efficient.

Always keep an eye on your oxygen supply while searching for Rubies in deep caverns. Having a high-capacity tank and a nearby vehicle allows you to collect gemstones without risking asphyxiation.

Key Uses for Aerogel in Crafting

Aerogel is essential for fabricating high-end vehicles and specialized equipment, including the Prawn Suit and Torpedo Launcher. It is also required to construct the Thermal Plant, which provides renewable power to bases situated near heat sources. Furthermore, building the Cyclops Docking Bay and various rocket components relies heavily on this composite material.

Stockpiling extra Aerogel at your main operational hub ensures you can quickly construct upgrades when needed. Proper resource management will streamline your exploration and base expansion efforts as you venture into the deepest ocean depths.
