Frequently Asked Questions

These are the questions the GAG community asks most often — about how the calculator works, how values are calculated, how trading works, and what to do when something doesn’t look right. If your question isn’t here, reach out through the Contact page.

About the Calculator

It’s a free, fan-made tool built specifically for Roblox’s Grow a Garden game. It calculates the exact Sheckle value of any crop or pet based on its weight (kg), mutations applied, quantity, and friend boost. It also includes dedicated tools for pet weight by age, egg hatch speed, pet XP calculation, and WFL trade checking. The goal is simple — no more guessing values in a trade, no more getting scammed because you didn’t know what your crop was actually worth.

No. This is an independent, community-supported tool. It is not affiliated with Roblox Corporation, BMWLux (the original game creator), Splitting Point Studios, or DoBig Studios. All data comes from verified in-game testing and community research, not from any access to the game’s source code or developer data.

Yes, completely free. No account, no subscription, no hidden fees. Every tool on the site — plant calculator, pet tools, egg hatch calculator, WFL checker — is free to use without registration.

Yes. The calculator is fully responsive and works on phones and tablets. Most GAG players use it mid-game on their phone while playing on a console or PC, so mobile performance was a priority from the start.

Plant and Crop Value Questions

Crop value follows this formula: Base Value × Mutation Multipliers × Weight × Quantity × Friend Boost. Each variable compounds the others, which is why weight and mutation combinations have such a dramatic effect on final value. A crop with a high base value but low weight and no mutations can be worth far less than a common crop with stacked high-multiplier mutations and significant weight.

Weight is the primary scaling variable in the game’s value formula. Unlike mutations which apply a fixed multiplier, weight scales the entire calculation — so even a small increase in kg at the higher end of the weight range produces a massive jump in Sheckle value. This is why two players can own the same crop species with the same mutations and have wildly different values depending on how their fruit grew.

They multiply together — this is one of the most misunderstood mechanics in the game and the reason high-mutation crops are worth astronomical amounts. Rainbow (50x) combined with Shocked (100x) is not 150x — it is 5,000x the base value. Add a Disco mutation (125x) on top of that and you’re looking at 625,000x the base crop value before weight even enters the equation.

Most mutations stack freely, but a few are mutually exclusive. The most important rule: you cannot have Gold and Rainbow on the same crop simultaneously — only one applies. The calculator automatically enforces all mutual exclusion rules, so if an option is greyed out after you select another mutation, it means the game itself doesn’t allow that combination. Here are the main stackable categories:

  • Colour mutations (Gold, Rainbow, Silver) — only one per crop
  • Environmental mutations (Wet, Chilled, Frozen, Shocked, Moonlit, Bloodlit, Chocolate, Disco) — most of these stack freely with colour mutations and with each other, with some exceptions like Wet and Frozen having a specific interaction
  • Combined mutations (Frozen = Wet + Chilled) — some mutations only appear when specific conditions combine in-game

As of the current update, the highest single mutation multiplier is Disco at 125x. However, combined mutations like Stormbound (270x) and Mindbender (175x) — which require specific mutation pairs to unlock — exceed it significantly. When stacking multiple compatible mutations on a high-weight crop, total multipliers in the millions are achievable, which is why top-tier GAG trades involve numbers in the trillions of Sheckles.

A few reasons this happens:

  • Different weight. Even a fraction of a kilogram difference produces a different value. Community-quoted prices are usually averages or estimates based on typical weights, not your specific crop.
  • Different mutations. They may be counting a mutation you don’t have, or not counting one you do have.
  • Outdated values. If the game updated recently, base values for some crops may have changed. Our calculator is updated to reflect the current game state — always use a fresh calculation rather than a cached community figure from weeks ago.
  • Friend boost difference. If you have an active friend boost and they didn’t account for it (or vice versa), the totals will differ.

Always calculate your own crop independently rather than relying on someone else’s number. That is the point of the tool.

We update values within hours of any significant game update — new plants, changed base values, new mutations, or event-specific items. When a new event drops in GAG, event plant and mutation data is added as quickly as the community can verify it through in-game testing. If you notice something appears outdated or missing, use the Contact page to flag it.

Pet Questions

Pet value is primarily driven by weight in kg, which increases as the pet ages from age 1 to 125. Unlike crops where weight is fixed at harvest, pet weight is dynamic — the same species at age 20 and age 100 can be worth completely different amounts. This is why age is always relevant in pet trading and why “what’s your pet worth” is not a question with a single answer.

Use the Pet Weight by Age tool in the Pets tab. Select your pet species, enter the age (1–125), and the calculator returns the expected weight for that age and an estimated trade value. This is the correct way to price any pet before trading — not by comparing it to community averages that may be based on different ages.

Because age and weight are the primary value drivers, not species alone. Two players can own identical pets and have a 10x value difference based purely on age. When someone in a trade forum says “my [Pet Species] is worth X billion Sheckles,” that number is only valid at a specific weight, which corresponds to a specific age. Always verify using the Pet Weight by Age tool before agreeing to any pet trade.

Kiwis and Eagles share a combined cap of 8 pets. You cannot exceed this cap with those species combined. This cap affects egg hatch speed calculations because the number and type of active pets changes how quickly eggs in your queue will hatch. The Egg Hatch Speed tool accounts for this cap automatically — enter your current active pet configuration and it gives you an accurate time estimate, not a generic average.

Pet XP determines how quickly your pet levels up, which directly controls how fast its weight — and therefore its value — increases. The Pet XP tool lets you plan AFK farming sessions precisely. Enter your current pets (up to 8 Owls with individual XP/second rates), add bonus sources like Brown Mouse, Grey Mouse, and Starfish, and the calculator tells you how long a session needs to run to reach a target age milestone. This is useful before major trading sessions when you want your pet at a specific age.

Trading and WFL Questions

WFL stands for Win, Fair, or Loss — the standard the GAG community uses to evaluate whether a trade is in your favour, roughly balanced, or costing you value. A Win means you’re receiving more than you’re giving. Fair means both sides are within a reasonable margin of each other. A Loss means you’re giving up more value than you’re getting back. The terms are used in every major GAG trading Discord, Reddit thread, and community forum.

Calculate both sides independently and compare the totals:

  1. Run your item (or items) through the plant or pet calculator with exact weight and every mutation applied. Note the total value.
  2. Run the item (or items) being offered to you through the same process. Same level of care — exact weight, every mutation.
  3. Compare the two numbers. If they’re within 10–15% of each other, the trade is Fair. If you’re receiving significantly more, it’s a Win. If you’re giving significantly more, it’s a Loss.

Never compare item names or rarity tiers alone. The calculated Sheckle value is the only accurate basis for a WFL assessment.

Value to Weight is the reverse of the standard calculator. Instead of entering weight to get value, you enter a target Sheckle value and the calculator returns the weight your crop would need to reach that price.

Use it when someone quotes a value for their crop in a trade and you want to verify it before accepting. Select their crop species, apply the mutations they’re claiming, enter the value they quoted, and see what weight their crop would need to be. If the number they’re claiming as the weight doesn’t match, the trade isn’t priced honestly.

Yes, at the high end of the game it absolutely is. A crop with a very high base value, significant weight (hundreds of kg), and multiple high-multiplier mutations stacked — for example, Rainbow (50x) + Shocked (100x) + Disco (125x) on a heavy exotic plant — can produce values in the hundreds of billions to trillions of Sheckles range. This is the nature of multiplicative stacking. However, always verify using the calculator rather than taking someone’s word for it. The tool exists precisely for these situations.

The most frequent ones we see in the community:

  • Misrepresenting weight. Claiming a crop weighs significantly more than it does. The Value to Weight tool catches this instantly.
  • Hiding mutations (or claiming ones that don’t exist). Always check every mutation yourself rather than trusting a screenshot, which can be manipulated.
  • Pet age misrepresentation. Claiming a pet is near max age when it isn’t. Pet Weight by Age catches this — if the weight doesn’t match the claimed age, the numbers don’t add up.
  • Comparing different things. Offering a flashy rare item against a less impressive but significantly heavier, more mutated common crop, knowing most players won’t calculate. Calculate everything, regardless of what it looks like.

Technical Questions

Values can differ between calculators for several reasons: different base value data (especially if one tool hasn’t been updated after a game patch), different mutation multiplier data, or different formulas for pet weight curves. Our data is sourced from verified in-game testing. If you find a consistent discrepancy on a specific plant or mutation, use the Contact page to flag it with the details and we’ll investigate.

It’s most likely a very recent addition — admin event mutations, seasonal event mutations, and combined mutations are sometimes added to the game faster than the community can verify and document them. Once verified through in-game testing, they’re added to the calculator. You can flag missing mutations through the Contact page.

Yes. The tool is entirely browser-based with no downloads or installations required. It runs on any device with a modern browser — Chromebooks, tablets, phones, and desktop computers. No Roblox login or account of any kind is needed.

No. The calculator is completely independent of your Roblox account. You enter values manually based on what you see in your in-game inventory. We have no connection to Roblox’s systems and do not access any account or game data.

One Final Note on Accuracy

This calculator is a fan-made tool. Grow a Garden is actively developed and updates frequently — new mutations, changed base values, new plants and pets, and event-specific items appear regularly. We work to keep data current, but in the hours immediately following a major game update, some values may lag slightly behind the live game. For the latest community-verified values during a new event, cross-reference with the official GAG Discord alongside your calculator results.
