How to Grow Mushrooms in Schedule 1
Shrooms sit between weed and meth on price but need a completely different setup — a cold room, a spawn station and a watering step. Here is the whole chain, from unlocking Fungal Phil to the mixes worth making.
The one number people get wrong
≤ 15°C / 59°F
Mushroom beds will not grow at all above 15°C. One AC unit is usually not enough — plan for at least two in cool mode near the bed. Hold the clipboard and press H for a live temperature heatmap to confirm the bed is actually in range.
Unlocking shrooms and Fungal Phil
Shrooms are gated behind Downtown, and Downtown is gated behind the cartel. The chain is:
- Drop Downtown’s cartel influence below 300 Downtown starts around 800 once you are hostile. Unlocking customers takes 75 off each, graffiti tags 50, and cartel dealers up to 200 — so it is roughly seven customers, or ten tags, or a mix. Note that none of it counts while you are on a truce. Full numbers in the cartel guide.
- Reach Friendly with Kevin Oakley or Elizabeth Homley Kevin is at the supermarket. Deliver requested products promptly, or hand them product before they even ask, to climb standing fast.
- Complete one more deal Fungal Phil texts you shortly afterwards and his introductory quest, Vibin’ on the Cybin, unlocks.
- Find Phil’s stash Round the back of the Central Gas Station, right next to the canal. Orders from him arrive as dead drops.
Equipment and startup cost
A single-bed setup runs about $3,725. The AC unit and spawn station are the two big one-off purchases; everything else is per-batch consumables.
| Item | Cost | Where |
|---|---|---|
| Mushroom Spawn Station | $1,500 | Oscar’s Warehouse (6pm–6am) |
| AC Unit | $1,800 | Dan’s Hardware |
| Mushroom Bed | $200 | Oscar’s Warehouse (6pm–6am) |
| Spore Syringe | $120 | Fungal Phil (dead drop) |
| Mushroom Substrate | $60 | Fungal Phil (dead drop) |
| Grain Bag | $20 | Fungal Phil (dead drop) |
| Spray Bottle | $15 | Dan’s Hardware |
| Trimmers | $10 | Dan’s Hardware |
The Mushroom Spawn Station and Mushroom Beds come from Oscar at the Warehouse, and he is only available between 6pm and 6am. Turning up at midday is the most common reason people think the items do not exist.
The growing process
- Inoculate the grain Load one Grain Bag and one Spore Syringe into the Spawn Station. Remove the syringe cap, tilt it toward the bag with A/D, insert the needle into the black square, and hold to push the plunger until the bar hits 100%. That gives you Shroom Spawn.
- Prepare the bed Add a bag of Mushroom Substrate to a Mushroom Bed, then add your Shroom Spawn. Click the spawn bag repeatedly to break it into roughly 16 chunks, then hold the mouse button and stir them through the substrate.
- Get the room cold Two or more AC units in cool mode. The unit displays the current temperature and you adjust it with the on-device buttons. Anything above 15°C and growth simply never starts.
- Water twice Fill the Spray Bottle at a tap. Blue target icons appear on the substrate — rotate with A/D and press Space to mist each one. A full spray only gets you to 56%, so you need two passes to max it.
- Wait and harvest Around 12 in-game hours to reach 100%. Each bed yields roughly 16 shrooms.
Pushing quality up
- Fertiliser to 100% coverage before growth completes raises the batch to ★ Premium.
- Two drying-rack cycles (24 hours total) takes it to ★ Heavenly, the top tier.
What shrooms are actually worth
Base price is $65 per unit — you can push the asking price to roughly $80–85 with no mixing at all. At ~16 per bed that is about $1,040 a harvest against roughly $200 of materials.
Mixing is where it gets interesting. Using this site's engine:
| Recipe | Effects | Sells | Profit | |
|---|---|---|---|---|
| Unmixed | None | $65 | $52 | |
| Viagra → Horse Semen | $129 | $103 | Open ↗ | |
| Viagra → Horse Semen → Iodine → Chili | $181 | $140 | Open ↗ | |
| Viagra → Horse Semen → Iodine → Chili → Battery → Addy | $234 | $176 | Open ↗ | |
| Viagra → Horse Semen → Iodine → Chili → Battery → Addy → Horse Semen → Motor Oil | $290 | $217 | Open ↗ |
These are generated by a greedy search, not community world records — see the caveat on the recipes page. Community guides also report Shroom + Banana + Cuke + Horse Semen + Mega Bean landing around $191/unit, and longer chains reaching $280+ on ★ Heavenly base quality.
Free shrooms without a grow
Mushrooms spawn in the corners of the sewer tunnels. If you have not built a setup yet, that is a no-cost supply — you just need the Sewer Key to get down there comfortably.
