What Is the Size Potion in Plants Vs Brainrots?
The Size Potion is a special Limited tier item introduced during the Plant Pantry Event in Plants Vs Brainrots Roblox. This potion is designed to help players grow bigger and more powerful plants to defend against brainrot invasions. When you use the Size Potion, it activates a 5-minute buff that increases the chances of your plant seeds growing into larger versions of themselves.
Bigger plants aren’t just for show, they pack a serious punch in battle. Larger plants can deal significantly more damage to incoming brainrots and have much higher HP (health points), making them last longer in tough fights. This means your garden defense becomes much more effective, allowing you to survive harder waves and earn more rewards.
The Size Potion has become incredibly popular among players because it offers a straightforward way to boost your garden’s power without complex strategies. Many players consider it “overpowered” due to how dramatically it can improve your plant performance.
How Does the Size Potion Work in Plants Vs Brainrots?
Using the Size Potion is simple, but understanding exactly how it works will help you get the most value from it. Here’s the step-by-step process:
First, you need to activate the Size Potion before planting your seeds. The potion creates a 5-minute window where any seeds you plant during this time have an increased chance to grow into bigger versions. It’s important to note that the potion affects the planting process, not existing plants, so you can’t use it on plants that are already growing.
During this 5-minute period, you’ll want to plant as many seeds as possible to take advantage of the buff. Each seed planted has a chance to grow larger than normal, though the exact percentage chance isn’t specified by the developers. Players have reported getting plants weighing 5-7 kg when using the potion, compared to the usual smaller sizes.
The effects are permanent for the plants that grow during the buff window. Once a plant grows larger with the Size Potion effect, it stays that size permanently and will continue to deal increased damage and have higher HP in all future battles.
How to Get Size Potion in Plants Vs Brainrots?
Getting your hands on the Size Potion requires participating in the Plant Pantry Event, which runs from December 15-22, 2025. Here’s exactly how to obtain this valuable item:
Access the Plant Pantry Event
First, you need to unlock access to the event area. This requires reaching Rebirth 1 and paying ₵1,000,000 Cash to unlock the Central Island. Once there, head to the Plant Pantry event area and find Chef Chubbeloni, the NPC who runs the event.
Complete Chef Chubbeloni’s Requests
Chef Chubbeloni will give you random plant requests every minute. You need to deliver the specific plants he asks for to progress through the event and earn rewards. The rarer the plant you deliver, the more points you earn toward the next reward.
The Size Potion is awarded at specific request milestones:
- 6th request: 1x Size Potion
- 17th request: 1x Fridgo Camelo and 1x Size Potion
- 22nd request (final): 1x Cannonoci Seed, 1x Chef Chubbeloni, and 1x Size Potion
Farm Unlimited Size Potions
If you want more than the three Size Potions available from the event track, you can restart the entire Plant Pantry Event by spending $100M in-game cash. There’s no limit to how many times you can restart the event, making it possible to build up a large stockpile of Size Potions if you’re willing to invest the time and resources.
What Are the Best Strategies for Using Size Potion?
To get the most value from your Size Potions, you need to use them strategically. Here are the best approaches based on player experiences and testing:
Time Your Planting Sessions
Since the Size Potion effect only lasts 5 minutes, preparation is key. Before activating the potion, make sure you have plenty of seeds ready to plant. Gather all the seeds you want to use and clear space in your garden so you can plant continuously during the buff window.
Many players recommend having at least 10-15 seeds ready before using a Size Potion to maximize your chances of getting multiple large plants.
Combine with Other Potions
Experienced players have discovered that combining the Size Potion with other potions can create even more powerful results. The most popular combination is using a Witch Potion along with the Size Potion. This combo has produced some of the largest plants in the game, with players reporting plants weighing 6-7 kg.
Focus on High-Value Plants
Not all plants are equally valuable when enlarged. Focus your Size Potion usage on plants that are already strong or have special abilities. Making your most powerful plants even bigger will give you the biggest boost to your garden’s overall defense capability.
Save for Important Moments
Since Size Potions are limited and require effort to obtain, save them for important moments in the game. Use them when you’re trying to progress to a new area, unlock a new biome, or defeat a particularly challenging boss brainrot.
What Are the Benefits of Bigger Plants in Plants Vs Brainrots?
Using the Size Potion to grow bigger plants offers several significant advantages that can transform your gameplay experience:
Increased Damage Output
Larger plants deal substantially more damage to brainrots. This means you can defeat waves of enemies faster and progress through the game more quickly. Players have reported that gardens with larger plants can handle waves that would otherwise be impossible to survive.
Higher Health Points
Bigger plants have more HP, making them much more durable in battle. They can withstand more hits from brainrots before being defeated, which is especially important in later game stages where enemies become much stronger.
Better Resource Generation
Since your plants survive longer and defeat enemies more efficiently, you’ll earn more cash and other resources over time. This creates a positive feedback loop where you can afford better seeds and upgrades, further strengthening your garden.
Visual Appeal
While not a gameplay benefit, many players enjoy the visual aspect of having massive plants in their garden. It’s satisfying to see your plants grow to enormous sizes and dominate the battlefield.
Can You Buy Size Potions Directly in Plants Vs Brainrots?
Currently, there is no direct option to purchase Size Potions in the game shop. The only way to obtain them is through the Plant Pantry Event as described earlier. However, players have found a workaround through trading.
You can potentially acquire Size Potions by trading with other players. If you have rare items or extra resources that another player wants, they might be willing to trade a Size Potion for them. Just be careful when trading and make sure you’re getting a fair deal.
The lack of direct purchase options makes the Size Potion more valuable and exclusive, which is why many players are working hard to farm as many as possible during the event period.
How Long Do Size Potion Effects Last?
The Size Potion effect lasts exactly 5 minutes from the moment you use it. This is a fixed duration and cannot be extended or shortened. During this 5-minute window, any seeds you plant have the increased chance to grow larger.
It’s important to note that the timer starts immediately when you activate the potion, so you should be ready to plant right away. Many players make the mistake of using the potion and then taking time to decide which seeds to plant, wasting precious seconds of the buff.
Once a plant grows larger during the Size Potion effect, it stays that size permanently. The 5-minute timer only applies to the planting window, not to how long the plants remain large.
Does Size Potion Affect Plant Fusion?
This is a common question among players, and the answer is somewhat complicated. Many players have reported that using the Size Potion can make plant fusion less effective or even counterproductive.
When you fuse two plants, the resulting plant’s size is determined by the sizes of the parent plants. However, some players have noticed that plants grown with the Size Potion tend to shrink when fused, potentially losing the size benefits.
If you’re planning to fuse plants, it might be better to use the Size Potion after fusion rather than before. This way, you can ensure that the final fused plant gets the size boost rather than having it potentially lost during the fusion process.
What’s the Biggest Plant You Can Get with Size Potion?
Players have reported some impressive results when using the Size Potion effectively. The largest plants documented by players include:
- A 5.9 kg carnivorous plant
- A 6.9 kg King Limone
- A “semi huge” electrified mango
- Ruby mango varieties reaching impressive sizes
These massive plants not only look impressive but also provide tremendous defensive value. Players who successfully grow these giant plants report being able to handle much stronger brainrot invasions and progress through the game more quickly.
The exact maximum size possible isn’t officially documented, but players continue to experiment with different combinations and strategies to push the limits of how large their plants can grow.
