What Are Seeds Used For?
Seeds are the main currency for summoning new plant units. Here’s what you need to know:
- Unit Summoning: Spend seeds to pull random vegetable towers from the gacha system
- Rarity System: Higher rarity units (0.1% to VIP) have better stats and abilities
- Rotation Schedule: Available units change every few hours
- Trading System: Trade duplicate units with the new Trader feature
I personally save my seeds for rotation periods that include S-tier units. Check the Garden Tower Defense tier list to know which units are worth your seeds.
