Hydroponics Delta is one of Neomuna's three lost sectors in Destiny 2: Lightfall. It's located in Zephyr Concourse, and with a recommended power level of 1750 for this area, you'll need to work your way through the Lightfall campaign to increase your chances at survival. If you're planning to do the Legend difficulty version of this lost sector--1830 power level recommended--so that you can potentially earn an Exotic, it'll have the following modifiers in play:

Where to find the Hydroponics Delta lost sector

　　Once the door is open, head inside and follow the path until you reach the hydroponics area,. jump into this area.

　　And then jump down once again, where you'll see an open spot in the floor.

　　You can now follow this path, which is populated with Shadow Legion Cabal. As you work your way through, the second encounter in the food production area will throw a small army of Cabal at you. Once you've eliminated them, you can jump through the passage that food tubes are leading through, to take on the final boss.

　　Once inside the main area, you'll be facing off against Valus Dravusk of the Shadow Legion. Like most Cabal bosses, Dravusk can absorb an absurd amount of damage while he returns fire. To make this area even more challenging, you'll also have to deal with Shadow Legion reinforcements in the form of Legionaries, Phalanx shield troops, War Beasts, and Centurions. Fortunately, there's a lot of cover in this area, so you'll want to use guerilla tactics to attack from behind cover and keep moving to the next section of the room that isn't so crowded.

　　Keep chipping away at Dravusk's health, deal with his troops, and you'll soon get the better of these Cabal. Once you've claimed the treasure cache in this room, you're free to leave it and return to the surface of Neomuna.
