There’s a wide variety of plants in Subnautica Below Zero, and many of them can be used for survival. In fact, it’s smart to build a farm that will provide you with fruits, vegetables, and other crafting materials. However, given the game’s aquatic world, there are only a few plants that grow indoors or in open-air environments. Here’s everything you need to know about indoor farming in Below Zero.
Subnautica Below Zero Farming: Indoor plants and food crops
There are six different exploitable plants in Subnautica Below Zero that can be grown indoors. Each of them provide fruit or vegetables that help manage hunger, thirst, health, and/or body temperature. However, before you can grow or farm them, you’ll have to discover the original plant and claim its fruit or seeds.
Here’s a look at each plant that can be grown indoors in Subnautica Below Zero. Since all plants require seeds to start growing, we’ve also listed the location where the source plant can be found.
Chinese Potato Plant
Chinese Potato Plants are one of the most easy-to-farm crops in Below Zero. The catch is that they can be hard to find. A few seeds are stashed away in a shipwreck, and the others you won’t find until you’re able to visit Marguerit’s Greenhouse later in the game. Either way, Chinese Potatoes provide +12 food and +3 water. Though the bonus is small, potatoes are great fuel for the Bioreactor.
- Yields: Chinese Potatoes
- Location: Marguerit’s Greenhouse; Mercury II Bow wreckage
Fevered Pepper Tree
The Fevered Pepper Tree is a towering plant that grows its namesake hot peppers. The fruit provides +15 food, +20 water, and +50 heat, but can also be used to craft the Spicy Fruit Salad, one of the best consumables in the game.
- Yields: Fevered Pepper
- Location: Arctic Spires, Glacial Basin, Glacial Bay, East Arctic, West Arctic
Horseshoe Shrubs are a great way to farm food early in Below Zero. You can harvest Shrub Nuts on the way to visit Outpost Zero, where you’ll find the first pieces of the Habitat Builder as well as various grow pots. Horseshoe Shrub Nuts provide +10 health, +15 food, and +5 water, making them one of only a few foods that address all basic needs.
- Yields: Shrub Nuts
- Location: Marguerit’s Greenhouse; Delta Island outpost
The Lantern Trees from the original Subnautica return in Below Zero. The limbs off these twisted trunks drop Lantern Fruits, which can be eaten raw to provide +15 food and +74 heat. Since Lantern Trees provide abundant fruit, they also serve as a steady fuel supply for the Bioreactor.
- Yields: Lantern Fruit
- Location: Outpost Zero
A staple of aquatic survival, the Marblemelon Plant provides big juicy melons at regular intervals. Unfortunately, the only way to farm it is to visit Marguerit’s Greenhouse, which isn’t possible until later in the game. Still, Marblemelons themselves provide +12 food and +14 water, making them a great way to satisfy both hunger and thirst without fishing or running a Water Filtration Machine.
- Yields: Marblemelons
- Location: Marguerit’s Greenhouse
Preston’s Plant is one of the new additions to Below Zero. Like the Marblemelon and Chinese Potato Plant, you can only find it at Marguerit’s Greenhouse. However, it grows in any open-air pot, and yields two different crops.
The fruit is called Preston’s Delight, and it provides +15 food and +5 water. Then there’s Preston’s Plant Leaf, which can be combined with Fevered Pepper to create Spicy Fruit Salad. The combined dish restores a whopping +100 heat, +85 food, and +30 water.
- Yields: Preston’s Delight; Preston’s Plant Leaf
- Location: Marguerit’s Greenhouse
You only need to grow a few indoor plants to survive in Subnautica Below Zero. Farming for fruits and vegetables provides a stable way to manage hunger and thirst at your base. However, if you’re taking the Seatruck Sleeper Module out for a long adventure, it’s still worth bringing along bottled water and cured fish.
