The Sprout Studies event in Plants Vs Brainrots is all about upgrading your garden by mutating your plant seeds. Starting January 10, 2026, at 3:00 AM PST (6:00 AM EST), you can visit Central Island where a purple lab replaces the old Gym. Here, you submit seeds to a mutation machine and get back powerful mutated plants with unique abilities. The event lasts about seven days, so let’s get into how you can join and make the most of it.
Here's a quick answer to get you started:
- Go to Central Island after reaching Rebirth 1 and paying 1,000,000 Cash.
- Submit any plant seed at the mutation machine outside the purple Sprout Studies lab.
- Wait up to 5 minutes for your seed to mutate and return with a chance for rare mutations.
How to start the Sprout Studies event and where to find it
To join Sprout Studies, you need to unlock Central Island by reaching Rebirth 1 and paying 1,000,000 Cash. Once there, you’ll spot the purple Sprout Studies lab where the Gym used to be. Just walk up to the mutation machine outside the lab and interact with it. No extra setup is needed : the event runs automatically for about a week.
What happens when you submit seeds and how mutation works
Submitting seeds is straightforward and rewarding. Pick any seed from your inventory and hand it over at the machine. You immediately get milestone progress and a reward. Then your seed moves inside the lab to the mutation machine. The mutation takes up to 5 minutes depending on the seed. After that, your mutated plant returns to your inventory. Your original seed isn’t lost; it just comes back transformed.
What kind of mutations can you get and how rare are they?
| Mutation | Chance | Image |
|---|---|---|
 Abomination | 85% | |
 Corrupted | 5% | |
 Amped Up | 4% | |
 Diamond | 3% | |
 Frozen | 2% | |
 Neon | 1% |
Abomination mutations are common and still strong. The rare Frozen and Neon mutations are special and highly prized.

Tips to get the most out of Sprout Studies
Keep submitting seeds regularly to unlock milestones faster. Since mutation takes up to 5 minutes, use that time to gather more seeds or work on your garden. Your seeds always come back mutated, so you can keep experimenting with different types to find rare mutations. Start with common seeds to quickly earn rewards, then try rarer seeds for a chance at Neon or Frozen mutations.
Bonus: special Admin Abuse events during Sprout Studies
During this event, developers sometimes run Admin Abuse events on public servers. These boost Brainrot spawns, speed up plant growth, and offer rare drops you can’t get normally. Joining these events is a great way to grab rare items and level up faster.
Sprout Studies adds a fresh, fun way to grow your garden in Plants Vs Brainrots. Just head to Central Island, submit your seeds, wait for mutations, and claim your rewards. With steady participation, you’ll unlock all milestones and add some powerful mutated plants to your collection.
