The Bulb Zone in Subnautica has a varied depth, ranging from 140 meters to 480 meters in its surface areas, and 220 meters to 315 meters within its cave systems.
This distinct biome is characterized by its signature Bulb Bush flora, giving the zone its unique name. Knowing the depth ranges is essential for players to ensure they have the appropriate vehicle upgrades and sufficient oxygen supply for safe exploration.
Bulb Zone Characteristics
The table below summarizes key environmental details and resources found within the Bulb Zone:
| Characteristic | Detail |
|---|---|
| Surface Depth Range | 140 – 480 meters |
| Cave Depth Range | 220 – 315 meters |
| Temperature Range | 13.8℃ – 14.1℃ |
| Harvestable Nodes | Sandstone, Shale |
| Large Resource Deposits | Gold, Lithium, Titanium |
Navigating the deeper sections of the Bulb Zone, especially its intricate caves, often necessitates a Seamoth equipped with a Mark 1 or Mark 2 depth module, or the robust Prawn Suit, to prevent exceeding crush depths. The consistent temperature range, hovering between 13.8℃ and 14.1℃, remains stable across all depths of the zone.
Explorers venturing into this area will discover valuable materials. Commonly found harvesting nodes include Sandstone and Shale, both crucial for various crafting recipes. Additionally, significant deposits of Gold, Lithium, and Titanium are present, making the Bulb Zone a prime location for resource acquisition. This area, situated to the east-northeast of Lifepod 5, also acts as a gateway to even deeper, more challenging biomes in Subnautica.
