Welcome to your ultimate guide to gardening in Subnautica! Whether you’re aiming for sustainable food sources, crafting essential materials, or simply sprucing up your base, this guide covers everything you need to know about plant cultivation in the deep.

Plant Categories in Subnautica

Plants in Subnautica fall into two main environmental categories:

• Aquatic Plants – Grow underwater and are cultivated in Exterior Grow Beds or Alien Containment Units.
• Terrestrial Plants – Grow on land and require Interior Grow Beds.

Functionally, plants can be grouped into three categories:

1. Edible Plants – Provide food and water for survival.
2. Utility Plants – Used in crafting and offer functional benefits.
3. Decorative Plants – Serve no gameplay function but enhance your base visually.

🌱 Utility Plants (Crafting & Functional Use)

These plants are crucial for crafting key components and supporting advanced gameplay systems:

Plant	Usage
Acid Mushrooms	Used to craft batteries.
Blood Kelp (Blood Oil)	Needed to make benzene.
Pygmy Bulb Bush	Used in high-tier fabrication recipes.
Creepvine	Produces fiber mesh and lubricant.
Deep Shrooms	Ingredient in hydrochloric acid.
Gel Sacks	Required to create aerogel.
Purple Brain Coral	Passively generates oxygen, useful in base design.
Sea Crown	Essential for crafting the enzyme cure.
Tiger Plant	Can attack predators, offering defensive capabilities.

🍎 Edible Plants (Food & Hydration)

While fish are abundant, plants provide renewable, land-based nutrition:

Plant	Food / Water Value
Marblemelon	High in both food and water; most efficient edible plant.
Lantern Fruit	Grows quickly; low nutritional value.
Chinese Potato	Solid food and moderate water source.
Bulbo Tree	Excellent water yield, some food benefit.
Creepvine Sample	Edible in emergencies; minor sustenance.
Gel Sacks	Small food and water bonus (not ideal for farming).

💡 Tip: Slice Marblemelons with a knife to collect seeds and maximize regrowth potential.

🌿 Planting & Farming Tips

Maximize your garden’s potential with these best practices:

• Exterior vs. Interior Beds: Use exterior beds for large aquatic plants and interior beds for land-based ones.
• Grow Bed Stacking: Build stacked gardens on multi-purpose room rooftops for space efficiency.
• Seed Efficiency: Some plants (e.g., Marblemelon) yield multiple seeds per harvest, ideal for self-sustaining farms.
• Bioreactor Fuel: While plants work as fuel, fish generally provide more energy.
• Defensive Use: Place Tiger Plants near entrances for basic protection against small predators.
