You know that moment when you're just trying to play a chill farming game and suddenly you’re deep in a spreadsheet with 200+ rows, half a dozen formulas, and you’ve googled “how to calculate exponential growth” three times in the last hour?
Yeah. That happened.
Let me introduce you to my weekend project-slash-obsession:
👉 https://growagarden-calculator.info
It’s a calculator for a Roblox game called Grow A Garden. If you’ve never played it, it’s kind of like a chaotic farming sim where you plant crops, mutate them (don’t ask how, it’s weird and I love it), and try to figure out which ones are worth the most.
The game gives you some information, but if you’re the kind of person who wants to know exactly how much value you're getting per gram of mutated potato… well, the game ain’t gonna tell you. So naturally, I decided to brute-force the answer.
Why though?
Honestly? Curiosity.
I started by jotting down a few crop prices in a notepad. Then I noticed some values looked… suspicious. Like, way too high for their weight. That’s when I realized there’s some sort of mutation multiplier going on. So I did what any rational human would do:
Open Excel → Get confused → Fire up VS Code instead.
And just like that, what started as “I’ll just check one thing” turned into “I guess I’m making a web app now.” 😅
What does the calculator do?
The site lets you:
- Look up crop base values
- See mutated versions (with multipliers)
- Compare crops by value/weight
- Cry when you realize you’ve been growing the wrong stuff all along
It's not 100% accurate — because, let's be real, Grow A Garden doesn’t exactly publish a whitepaper on how weight works. But I reverse-engineered a bunch of values, and it’s pretty close. Most of the logic is just good ol’ guesswork + testing in-game.
The tech stuff (if you’re into that)
It’s a tiny frontend app, no backend or database (yet). Just pure static hosting, TypeScript, and a JSON file with all the crops. I used a simple framework (shoutout to Astro, or whatever I felt like that day), and focused more on functionality than fancy UI.
But hey — it works on mobile! So you can theorycraft while you’re waiting for your lettuce to mutate into an eldritch abomination.
Got feedback? Roast me.
Seriously. If you try it out and something feels off, weird, or broken — let me know. You can ping me on Reddit (I lurk in r/GrowAGarden more than I should) or just yell at the sky and I’ll probably hear it.
Also, if you’re a dev and you play GaG too, hit me up. We can start a support group.
Final thoughts
I didn’t set out to make this tool. I just wanted to know why my carrots weren’t making money. But now it exists, and if it helps even one person squeeze a few extra coins out of their pixel crops, I consider that a win.
Anyway, thanks for reading my ramble. Go forth and grow weird mutated vegetables. 🌽✨
Peace. 🧡
