How To GET PREHISTORIC PLANTS FAST (in Grow A Garden! Guide)

Are you grinding Grow A Garden on Roblox and wondering how to get prehistoric plants fast? Maybe you’ve seen other players flexing their upgraded DNA Machine and earning shekels like crazy—and now you want in.

Well, you’re in the right place! In this guide, I’ll show you exactly how to farm prehistoric plants quickly, maximize your machine upgrades, and avoid costly mistakes that waste your rare seeds.

🦖 What Are Prehistoric Plants?

Let’s start with the basics: Prehistoric plants are special crops that come from two main sources:

1. Exotic Ancient Seed Pack
   These include rare seeds with high weight (measured in kg), which are essential for DNA machine progress.
2. Craftable Seeds (NEW Update)
   Some prehistoric plants can now be crafted manually, including:
   • Horsetail
   • Lingonberries
   • Amber Spine
   • Grand Volcania

Any of these count toward prehistoric plant progress and can be traded in for DNA machine upgrades—which reduce cooldowns and unlock new functionality.

💥 Why You NEED the DNA Machine Upgrades

Upgrading your DNA Machine does more than make it look cool:

• ⏱ Reduces cooldown times
• 🔁 Improves functionality (more mutations, faster processing)
• 💰 Helps automate part of your farm

But here’s the trick: it requires massive kilograms of prehistoric plants to upgrade. So let’s get to farming them fast.

⚙️ The Fastest Way to Get Prehistoric Plants

1. Use High-Kilogram Plants (like Bone Boo)

The heavier the plant, the faster you level up the DNA Machine. Right now, some of the best prehistoric plants include:

• Bone Boo (~20 kg each!)
• Firefly Ferns
• Horn Diamond Mushrooms
• Amber Spine (crafted)

💡 Pro Tip: Even if you only get one of these per pack, farm it anyway. You’re going for weight, not quantity.

2. Spam Them in Your Garden

Once you have a prehistoric plant seed:

• Plant it repeatedly across your garden.
• Use pets like Butterfly, Dragonfly, or Capybara to mutate them.
• Focus on maximizing growth speed using sprinklers or mutation tools.

BIG MISTAKE to Avoid: “Take All My Prehistoric Plants”

This one is huge.

The DNA Machine has an option: “Take All My Prehistoric Plants.” It sounds tempting, but DON’T click it.

Why?

Because:

• It only upgrades ONE level no matter how many kilograms you donate.
• Extra plant weight is wasted — it does not roll over to the next level.
• You’ll lose rare seeds without getting full value.

✅ Instead: Manually feed your prehistoric plants to the DNA machine one upgrade at a time.

What Happens at Max Level?

Once you max out the DNA Machine:

• Cooldowns become much shorter
• Processing prehistoric seeds becomes faster
• You unlock rare mutations more easily
• Farming becomes way more efficient and automated

This helps you level up your entire garden empire.
