How to get a growbed in Subnautica 2

Building a growbed in Subnautica 2 creates an unlimited supply of food, water, and medicine. As you can turn fibrous pulp into water and food (at the processor and fabricator, respectively), keeping an ever-replenishing batch of pulp-producing plants at your home base is extremely handy. Plus, a custom-made oceanic garden looks quite lovely, especially at night.
