Walkthrough
You’ll see the greenhouse almost immediately after walking into Talos I Arboretum during Detour. When you get close, you’ll hear people begging for help or telling you to stay away — one of those people is Rani Chaudhary, the subject of Prey’s Save Rani optional objective.

When you approach the front doors, look on the ground for a note from Rani explaining the situation. The doors are locked and controlled from the computer to the right of the door. You have two choices to get inside: Find the password for the computer, or hack your way in. Hacking it requires hacking 3. Finding the password requires a bit of a walk.

Head toward the crew quarters entrance, but don’t go inside. Facing the entrance, turn to your left. There’s a narrow stairway that leads up to a balcony. Sweep the balcony and Iris Stein’s corpse for loot — there’s a Weapon Upgrade Kit to her left, a Neuromod on the table in front of her, she’s carrying a recycler charge and there’s various other loot and trash around.

The password is on a note on the floor at her feet. Head back and use the computer to unlock the doors.

Save Rani from Telepath
Your job here is to kill the Typhon Telepath while protecting (not killing) the humans. You’ve got a lot of options here, but you have to make sure the humans don’t get close to you or their heads will explode (which will kill them). Once you start attacking the Telepath (or when it notices that the doors are open of if you turn on the sprinkler system from the computer terminal) it will flee. Just make sure you keep your distance from the humans if they’re still mind-controlled. Keep after the Telepath when it flees, and keep its offensive abilities in check with Nullwave Transmitters or Psychoshock.
 * Your Disruptor Stun Gun or the Mindjack Neuromod ability will free the humans from the Telepath’s control without the head-exploding side effect.
 * GLOO will knock the Telepath down and keep it from attacking for a couple seconds.
 * Nullwave Transmitters or the Psychoshock ability will knock out the Telepath’s abilities for a few seconds.
 * Set up some turrets nearby. They won’t do much damage, but they’ll give it something else to attack.
 * Combat focus and your Q-Beam will make (relatively) short work of the Telepath.
 * Electrostatic Burst will stun the Telepath, allowing you to quickly kill it with the Q-Beam.

When the Telepath is dead, get back inside the greenhouse. Rani will be the only one conscious. She’ll tell you about some extra turrets in a storage closet nearby, and she’ll give you the access code. If you knock her unconscious before defeating Telepath, she's still can be awake and will contact Morgan once she awakes, telling to meet up with her at Arboretum and most likely on manufacture chamber.

Before you leave, sweep the greenhouse for stuff to pick up. There’s nothing exciting to find, but there are plenty of spare parts, food and ammo.

Access Storage Closet
The storage closet is about halfway between the greenhouse and the entrance to deep storage. When you get to the elevator lobby entrance, turn right, and follow the the path around to the left. At the top of the hill, the storage closet will be on your right.

Opening the door will complete the objective. Inside, you’ll find two turrets, two Silenced Pistols, a Shotgun, some Q-Beam cells and a Weapon Upgrade Kit.
