Start this quest by talking to Doctor Camden, who can be found on the Docking Bay/Common Area of the Nexus, near hydroponics. He’ll task you with finding plant samples on various planets throughout the Heleus Cluster. Like Eos, Voeld only has one plant of interest, and this one comes from the Angara - who else would know how to grow anything edible on this ice rock? Make your way to the western end of the Techiix Station, where you’ll find numerous gardens full of orange mushrooms… more Heleus Fauna you can scan and harvest.
