Find out what the Wet Mutation Spray does in Grow a Garden Roblox and how to use it to get rare mutated crops.

In Grow a Garden, mutations aren’t just cosmetic; they’re your key to unlocking higher-value crops, rare seeds, and progress with limited-time updates. One of the newest additions, the Wet Mutation Spray, plays an important role in getting specific mutation effects during the Mutation Spray Merchant event. If you’re wondering what the Wet spray does, how to use it, and how it compares to other sprays, this guide covers everything you need to know.
What Is Wet Mutation Spray in Grow a Garden
The Zen update in Grow a Garden introduced the Wet Mutation Spray as one of four new sprays from the Mutation Spray Merchant. When you use it on a plant, it guarantees a Wet mutation. This mutation makes the crop look damp and mossy.
Wet is one of the most common mutations in-game, which players can usually get when it rains, but seeing the number of weather types we have now, it makes it a bit difficult to obtain. But unlike natural mutation methods that rely on weather or RNG, this spray gives you full control over what mutation the plant will get.

How To Use Wet Mutation Spray
Using Wet Mutation Spray is simple:
- Equip the spray from your inventory (after purchasing from the merchant).
- Walk up to a fully grown crop.
- Press the spray button when prompted.
The crop will immediately mutate into its Wet version, changing its appearance and gaining mutation effects. You can also use Wet spray to force mutations on multi-harvest plants like Serenity or Maple Apple to boost rewards.
Where To Get Wet Mutation Spray

The Mutation Spray Merchant, an NPC who appears in the main hub area next to the seed vendor on the left, sells the Wet Mutation Spray for 50,000,000 Sheckles.
If the merchant isn’t currently active, check back after 30-45 minutes; this NPC rotates in and out of the hub depending on the servers.
Best Crops To Use Wet Mutation Spray On
The Wet spray works best on:
- Event crops that require Wet mutations to progress quests.
- Multi-harvest plants like Serenity, where every flower mutated boosts your output.
- Zen seed pack plants, especially if you’re working toward Chi Points or Tranquil fruit goals.
