Acid and Phosphorus are essential components for your liquid product in Schedule 1. If you’ve come across these ingredients before progressing in the main quest, you might be unsure where to procure them. This guide provides you with detailed instructions on how to acquire Acid and Phosphorus effectively in Schedule 1.
How to Acquire Acid and Phosphorus in Schedule 1


To obtain Acid and Phosphorus, it’s crucial to speak with Oscar at the Warehouse after 6 PM. Access to the Warehouse becomes available only after you complete the quest titled “Wretched Hive of Scum and Villainy.”
Each ingredient—Acid and Phosphorus—costs $40, which can be quite a burden on your finances, especially if you’re low on funds when creating your plant products. It’s advisable to buy as many as your budget allows. Keep in mind that each ingredient stacks up to 10 in your inventory slots, so be sure to organize your items before attempting to purchase in bulk.
Be aware that law enforcement often patrols near the Warehouse entrance, so it’s best to navigate around the side to evade them. If you are spotted, make your way towards the motel side for cover, since the back of the Warehouse is a dead end and could lead to complications.
Uses of Acid and Phosphorus in Schedule 1

Acid and Phosphorus, when combined with Pseudo at the chemical station, yield the crucial liquid product. Given that both Acid and Phosphorus are priced at $40, and considering the high cost of Pseudo depending on its quality, producing this liquid can cost over $120 per cycle.
