Living under the sea isn’t exactly easy in Subnautica 2. There’s a lack of food, ironically, there’s a lack of water, and there are giant sea-monsters hell-bent on hunting you down. The Growbed is one of the most useful blueprints to unlock early on in Subnautica 2, as it can start to make surviving that little bit easier.
Where to Get Growbed Blueprints in Subnautica 2
The first step in getting the Growbed in Subnautica 2 is to acquire its blueprints. To find the blueprints, head directly east from the lifepod. You will have to pass the Collector Leviathan, so make sure that you’re prepared to evade it, and keep on heading east until you hit the alien ruins.

Once you’ve found the alien tower shown above, you’re getting close. Head on over to it and start heading northeast, looking at the platforms below until you see some human ruins.
If you can’t find it, keep going around the tower and looking at the platforms below until you do find it. Or, head on over to: -210294, 428358, -12585, where you should find the abandoned underwater building with a Growbed on the floor, and another on the roof of the building.

Scan both Growbeds, and you will unlock the blueprint, letting you build them back at your base.
How to Use the Growbed
Now that you’ve found out how to unlock the Growbed blueprint, it’s time to start planting. Head back to your base and build your first Growbed. Before you go running to build your farm inside your base, these are external Growbeds; they only work outside.

Another thing to take note of is that they also need to be built on a building, and they won’t work if you try building them on the ground. Which is quite odd considering one of the ones we scanned to unlock the blueprint was, in fact, on the ground itself.

Once you’ve placed down the first Growbed, instead of building more, you will be given the option to simply make the first one you built bigger, saving you from needing to plan out where to put multiple Growbeds.
How to Plant in the Growbed
In most survival games, you collect seeds around the map, and simply press E (or the action button, depending on what you’re playing on), and that will automatically plant the seed in the Growbed.
With Subnautica 2, you need to use your Habitat Constructor to plant the seeds as if you were placing down a building.

Simply select the seed you want to place into the planter, and the location where you want it to go, and continue as if you were placing a building part. Once it is placed, all you need to do is wait for the plant to start growing.

As soon as the plants are fully grown, you can simply hit them with the Survival Multitool to collect the resources. If you’re not sure how much growing they’ve got left to do, simply get really close to them, and you’ll see a percentage showing you.
