The Trucker Spray applies the Farm mutation, which multiplies a crop's sale value by 4×. You can't buy it — it's a reward for earning an A, S or S+ grade from the Trucker NPC during the Trucker Event. Because mutations stack since Update 6, the Farm mutation layers on top of your other mutations as a dependable, always-on multiplier.
The Trucker Spray applies the Farm mutation (4×) to a crop. Unlike weather mutations, it needs no active event — once sprayed, the multiplier stays on the crop. A quick worked example: a crop with a $1,000 base sells for $4,000 after the Farm mutation, and placed on the Outer ring (19×) that becomes $76,000 per harvest before quantity. And because mutations stack since Update 6, you can layer Farm on top of Fire, Cosmic or Rainbow for a much larger combined multiplier. Try the maths in the income calculator. The 4× value is community-reported.
The Trucker Spray is a Trucker Event reward, not a shop item — one of several events in the game. During the event, a Trucker NPC grades your farm on a scale from F up to S+. Reach an A, S or S+ grade and the Trucker Spray is among the rewards. To raise your grade, build out and upgrade your farm before the event scores you — more developed, higher-value farms grade higher. Event timing and the exact grade thresholds are community-reported and can change between patches, so treat them as estimates.
The Trucker Spray isn't the only prize. Higher grades reportedly also yield other sprays and seeds — community guides list the Radioactive Spray, Void Spray, Diamond Blossom and Horned Melon seeds among Trucker rewards. We haven't confirmed these from in-game screenshots, so treat the reward list as community-reported until verified.
If you miss the Trucker Event, some pets grant the same Farm mutation passively. The Kitsune, Hydra and Mammoth all apply Farm (4×) — and the Mammoth needs no Robux, making it the best free route to the multiplier. (The T-Rex is a different kind of mutation pet: instead of applying Farm, it upgrades a nearby crop's existing mutation.) See how they rank on the pets tier list, and compare every mutation on the mutation table.

It applies the Farm mutation, which multiplies a crop's sale value by 4× (community-reported). The mutation stays on the crop and, since Update 6, stacks with other mutations — so it's a reliable always-on multiplier you can layer under event mutations.
Earn an A, S or S+ grade from the Trucker NPC during the Trucker Event. The Trucker Spray is one of the rewards for high grades. Upgrade and expand your farm before the event so it scores higher.
No. It can't be purchased — it's only obtainable as a Trucker Event grade reward. If you can't reach the required grade, the Kitsune, Hydra or Mammoth pets apply the same Farm mutation instead.
An A, S or S+ grade is reported to reward the spray. The grade scale runs from F to S+, and higher-value, more developed farms grade higher. Exact thresholds are community-reported and may change between patches.
Yes. Since Update 6, mutations multiply together, so the Farm mutation's 4× compounds with mutations like Fire (10×) or Cosmic (8×). Older guides saying "one mutation only" are outdated — see our mutations guide.
