Bonsai Vase – Air Pruning Planter & Spiky Planter

Stop cutting roots. Let air and structure do the work.

Traditional bonsai pots create circling roots that eventually need aggressive trimming. These two planter variants solve the problem in their own way — the right shape for every growing style.

🌿 Air Pruning Planter

Purple, ribbed design

The surrounding ventilation slots in the ribbed pattern automatically stop every root that reaches the pot wall — air contact halts growth and triggers natural branching. No scissors needed.

Features

• Natural root branching through air contact
• Permanently prevents root circling
• Compact 13 × 6 cm footprint
• Ideal for bonsai, cuttings, and small tropical plants
• 3D printable, no supports required, minimal material usage

🌵 Spiky Planter

Red, triangle pattern

The striking geometric triangle pattern is more than decoration — the openings provide targeted airflow while giving the planter its bold, edgy character.

Features

• Decorative triangle airflow pattern
• Targeted ventilation for healthy root development
• Compact 13 × 6 cm footprint
• Perfect for bonsai and small tropical plants
• 3D printable in PLA or PETG, no supports needed
