The Ghost Weed is a flora species found in deep biomes. The ghost weed is most commonly found in the Lost River but can also be found in large numbers in both Blood Kelp Zones, while a very limited amount of specimens can be found in the Bulb Zone and the Mountains.

It can be harvested for Ghost Weed Seeds with a knife or a thermoblade. One seed takes 2x2 inventory slots and can be planted in an Alien Containment or an Exterior Growbed. It takes 1200 seconds (20 minutes) for a mature Ghost Weed to grow from a seed.

Each plant has 150 HP and can therefore be slashed 8 times before being destroyed. The last slash will grant an additional seed, for a total of 9 seeds.

The seeds can be put into a bioreactor for 70 units of energy per seed.

Appearance

The Ghost Weed boasts a peculiar appearance. It has a green and red bulbous base, followed by two long green stems, each with several small protrusions near the tip and three short red stems, giving off a dull bioluminescent glow.

Trivia

The Ghost Weed was originally called the Red Green Tentacles.

Ghost Weeds once lacked the brine damage immunity afforded to the majority of life forms inhabiting the Lost River. Due to this, Ghost Weeds that were in contact with brine took damage upon loading in and would die, causing them to vanish. This oversight was most visible in the Ghost Forest.
