You’ve built your first base in Subnautica: Below Zero! After hours of swimming around gathering materials and using the habitat builder, you're ready to enter your new home and…what’s that? No power? Fear not, we’ve got a list of 12 flora and fauna that will power your Bioreactor with ease.
12. Lantern Fruit
You can eat them, then pop the the leftovers in the Bioreactor.

What makes Lantern Fruit Great:
- Dual use: Lantern fruits are helpful as Bioreactor fuel and as a food source.
- Easy harvest: You don’t need to keep replanting anything. Once you pluck the fruits, you simply wait for them to grow.
Lantern Fruit Stats:
- Lantern fruit takes up 4 slots of the Bioreactor inventory.
- The value generated in one space is 52.5, so the total value for one fruit is 210.
