How to get and use Void Spray
Unlike the Trucker Spray, Void Spray is a standard Gear Shop item once you have enough cash.
- 1
Save $10B cash
Void Spray unlocks in the Gear Shop at $10,000,000,000 cash (R$ 79). Most players reach this after pushing Seed Luck and filling the Middle Ring with Epic crops.
- 2
Buy from the Gear Shop
Open the Gear Shop on the right side of the map. Void Spray restocks on a timer like every other spray — use Restock Spray or wait if it is sold out.
- 3
Equip and click a plant
Equip Void Spray from your inventory, then click a fully grown crop. The Void mutation replaces any lower-tier mutation on that plant.
- 4
Upgrade when affordable
Radioactive Spray ($100B, 3×) and Rainbow Spray ($1T, 5×) are the natural next steps. Use Acid Spray ($1M) first if you need to clear a higher mutation before downgrading.

Void Spray FAQ
What does Void Spray do in Build A Ring Farm?
It applies the Void mutation, multiplying that plant's sale value by 2.25×. Equip the spray and click any crop — the Black Hole mutation is applied instantly.
How much does Void Spray cost?
$10,000,000,000 cash or R$ 79 in the Gear Shop. The natural Void mutation can also roll during Black Hole weather events at 3% per plant.
Is Void Spray worth it?
Yes for mid game. The jump from Wet (1.35×) or Autumn (2×) to Void (2.25×) is cheap relative to Radioactive ($100B, 3×). Put Void on your best Middle Ring crops until you can afford Rainbow.
Void Spray vs Radioactive Spray?
Radioactive is 3× for $100B — 33% stronger but 10× the price. Void is the better first paid spray; save Radioactive for Outer Ring Transcended crops.
Can I stack Void with another mutation?
Each plant holds one mutation, and Void Spray replaces whatever is there. The only exceptions are the pet-applied Starfall (Starfall Griffin) and Vine (Plant Rush Golem), which land on top of an existing mutation — additively, so Void plus Vine is 5.25×, not 6.75×.
