Fix the Hydroponic Farms in Adytum
The resident scientist of Adytum in the LA Boneyard, Miles, neads some parts to fix the Hydroponic Farms. You will find him standing outside a small shack near the farms to the south. He will suggest to speak to Sammael for more information.
Ask for information from Sammael in a tent near the farms. He can give you information about the area and will tell you that one of his scavengers reported finding near the Deathclaw nest.
Head north to Downtown and then East to the Death Claw nest.
Near a couple of the Deathclaws, you will see a body. Search the body to find the parts you need.
Return to Miles and show him the parts. He will ask you to bring them to Smitty to fix.
Bring the parts to Smitty in his house to the northeast and he will fix them for you.
Return once again to Miles with the fixed parts and he will thank you for your help. He will reward you with some caps and Stimpacks.
Hardened Power Armor
After you have helped Miles fix the Hydroponic Farms, return to him while you are wearing Powered Armor and he will offer to try to improve it for you. He will ask that you get some special books from Mrs Stapleton in the Library in the Hub.
Go to the Hub and speak to Mrs Stapleton. Buy the books that Miles wanted from her.
Return to Miles in the Boneyard with the books and he will turn your Powered Armor into Hardened Power Armor.
