This chapter of the Deep Rock Galactic guide has all the information about Barley Bulb - where to find it, how to identify, and what it can be used for.
Barley Bulb is one of the additional resources available in Deep Rock Galactic. This narrow plant on a long leg with a red bud at the top is used for brewing liquor or buying beer concessions at the bar on the space station.
Barley Bulb flowers can be found throughout the planetary system. They usually grow near the ground so they are easy to collect.
