Regrow farming is a technique in BTD6 used to generate large amounts of bloons repeatedly to maximize XP, farm cash, or prepare for Paragon upgrades. Regrow bloons automatically reproduce after being popped, creating a sustainable cycle that can be exploited for controlled farming.
How Regrow Farming Works
Regrow bloons return to their original state after being popped, allowing you to create a loop of endless bloons. By carefully controlling damage output, you prevent the loop from breaking too early, letting your towers accumulate pops and XP efficiently.
Best Bloons for Regrow Farming
- Regrow Reds, Blues, and Greens: Easy to maintain loops
- Regrow Yellows: Faster but still controllable
- Regrow Pinks: For experienced players with high micro skill
Avoid Regrow Rainbows unless you have strong control, as they can quickly overwhelm your setup.
Best Maps for Regrow Farming
- Cubism: Multi-loop paths ideal for controlled farming
- Four Circles: Split paths allow consistent regrow loops
- Resort: Tight loops simplify tower placement
- Logs: Beginner-friendly with slow-moving tracks
- Adora’s Temple: Long paths and predictable movement
Core Setup for Regrow Farming
1. Build a Controlled Loop
Use towers that deal light damage to avoid breaking the regrow cycle:
- 0-2-2 Dart Monkey
- 0-0-2 Sniper
- 0-0-2 Sub (water maps)
2. Add XP or Farm Targets
Place the tower you want to level or farm near the loop:
- Dart Monkey
- Ninja Monkey
- Boomerang Monkey
- Wizard
- Engineer
This ensures maximum pops go to your target tower.
3. Support Without Breaking the Loop
- Village 2-2-0: Minor buffs, no global damage
- Alchemist 3-0-0: Buffs towers without heavy burst
- Obyn Greenfoot: Adds mild support safely
Avoid towers with high AoE or global damage, as they can destroy the loop too early.
4. Ending the Loop
Once you’ve gained enough XP or cash:
- Activate abilities
- Add high-damage towers
- Send a MOAB-class bloon to collapse the regrow cycle
This prevents accidental bloon overflow.
Advanced Tips
- Use Sandbox to test setups before attempting real games
- Keep attack speed low on supporting towers to prevent stealing pops
- Use single-target towers for controlled XP accumulation
- Start loops early for maximum scaling
Conclusion
Regrow farming is a key strategy in BTD6 to maximize tower XP and farm resources. By creating stable loops, carefully choosing maps, and placing your towers strategically, you can farm bloons efficiently and accelerate Paragon unlocks.
