To unlock the Growbed blueprint in Subnautica 2, you must scan two Growbeds near the power plant area. The two Growbeds are placed near each other, so if you know exactly where to look, you will be able to unlock the blueprint very quickly. Below are the locations of the two Growbeds and directions on how to get the blueprints.
Start at the Power Plant Area

To locate the Growbed blueprint, go to the area of the power plant and the large tower. Next to it is a structure called Rosetta Stone. From there, continue northeast, and you will reach the precise location of the structure where you’ll find the first Growbed (the players are likely to visit this site as they progress through the main storyline).
Scan the First Growbed

Once you’ve reached the area, you’ll need to inspect the roof of the structure in front of you. The Growbed is on top of the roof, and can be easy to miss at first glance. What you’ll need to do is scan the first Growbed on the roof to collect the first blueprint fragment.
Scan the Second Growbed

To scan the second Growbed, you do not need to leave the biome or the area where you scanned the first Growbed. Simply search the ground to the left of where you scanned the first Growbed, and you will find the second Growbed. You must scan this Growbed to fulfill the requirements for getting the blueprint. Once you have completed scanning both Growbeds, you will have access to the Growbed blueprint.
