Grow A Garden just keeps getting better with each update, and the latest Prehistoric Event proves it once again. With the arrival of dinosaur pets, ancient-themed quests, and time-limited goodies, there’s one feature that has many players scratching their heads — the Old Amber Mutation.
If you’re hoping to add this rare mutation to your produce and rake in some serious Sheckles, this guide covers everything you need to know about how to get the Old Amber Mutation in Grow A Garden.
What Is the Old Amber Mutation?
The Old Amber Mutation is a rare transformation that can occur in your crops when exposed to Amber Mutation effects. Think of it as a powerful ancient upgrade that significantly boosts the value of your produce. It’s not just cosmetic—it has real selling value in the market and is essential for serious farmers who want to maximize profit during the event.
However, getting your hands on it isn’t easy. It’s a time-based transformation that requires patience and a bit of strategic investment.

How to Get the Old Amber Mutation
There are two known methods to trigger the Amber Mutation in Grow A Garden, but only one can actually lead to the Old Amber:
Method 1: Use the Mutation Spray Amber (The Only Guaranteed Way)
The Mutation Spray Amber is a special item you can craft during the Prehistoric Event. When applied to your crops, it adds the Amber Mutation, which can later transform into Old Amber or even Ancient Amber over time.
Players have reported that the Old Amber transformation takes roughly 48 hours (real-world time) after application, while Ancient Amber may take longer. Just apply the spray and let the crop evolve naturally — no skipping time, no shortcuts.
Pro Tip: Do not sell your produce too soon. Wait until the Old Amber or Ancient Amber transformation completes to get the best returns. Selling early means wasting a very expensive investment.
Method 2: Use a Raptor Pet During Harvesting
While equipping a Raptor as a pet during harvesting also applies the Amber Mutation, this does not result in the Old Amber or Ancient Amber versions. It’s a cheaper method, yes, but lacks the long-term value and transformation potential.
How to Craft Mutation Spray Amber
If you want the Old Amber Mutation, you’ll need to craft Mutation Spray Amber, which isn’t exactly cheap. Here’s what you’ll need:
Crafting Recipe:
- 1x Cleaning Spray
- 1x Dinosaur Egg
- 1 Million Sheckles
While the Dinosaur Egg and Sheckles are grindable, the Cleaning Spray is the real bottleneck.
Where to Get Cleaning Spray:
You can only purchase Cleaning Spray from the Gear Shop for a whopping 15 million Sheckles. That’s right — fifteen million. This makes it one of the most valuable items in the game, and one of the biggest investments you’ll need to make to pursue the Old Amber path.
💡 According to Insider Gaming, the Mutation Spray can only be used once, so be absolutely sure before using it.
Once you have all the components, head to the Event Store in the middle of the island to craft your Mutation Spray Amber.
How Long Does It Take for Old Amber to Appear?
While there’s no official timer visible in the game, community feedback suggests:
- Old Amber: Takes about 48 hours to form.
- Ancient Amber: Might take even longer—possibly up to 72 hours or more.
You’ll need to keep your mutated crop in the garden and resist the urge to sell or replant it. Patience is key here.
Is It Worth the Investment?
Let’s break it down:
Item | Cost (Approx) |
---|---|
Cleaning Spray | 15,000,000 Sheckles |
Dinosaur Egg | Event drop or purchase |
Mutation Spray Crafting Fee | 1,000,000 Sheckles |
Total | ~16,000,000 Sheckles |
That’s a lot of Sheckles. But once the Old Amber Mutation takes effect, the value of the crop skyrockets. Many players report massive returns on their investment if they’re willing to wait.
This makes it a worthwhile strategy for players who are serious about maximizing profits during the event window.
What Else to Do During the Prehistoric Event?
If you’re looking to make the most of this limited-time event, don’t just stop at mutations. Here’s what else you can explore:
- Collect dinosaur pets like the Triceratops, Brontosaurus, and T-Rex
- Complete new prehistoric quests to earn rare rewards
- Visit the Event Store for exclusive items and tools
- Hunt for rare dinosaur eggs to help with crafting
You can also find helpful community updates and player strategies in places like the Grow A Garden Wiki or discussion threads on Reddit’s Roblox board.
Final Tips Before You Craft
Before you burn your 15 million Sheckles and go all in:
- Make sure your crop is worth mutating (high-value crops = better return)
- Clear enough space in your garden to allow the transformation process
- Log in daily to check the progress — though you can’t speed it up, you can monitor for the exact moment Old Amber appears
- Don’t waste it on crops you plan to sell early. Wait for the full mutation to complete.
In Summary
The Old Amber Mutation is one of the most rewarding features of Grow A Garden’s Prehistoric Event, but it comes at a cost — time and money. If you’re committed to farming in the long run and willing to make the big investment, the returns can be well worth it.
Craft smart, wait patiently, and let evolution do the rest.
