✔ No CO2 required. Grows in low-tech tanks under moderate light. CO2 accelerates growth and triggers pearling but is not essential.
🫗 Pearling = plant health signal. Tiny oxygen bubbles on leaf surfaces during rapid photosynthesis. Most visible with CO2 + high light; also occurs without CO2 in high light.
🌿 Three Keys
Betta tanks at 25–28°C: Pearl Weed fully compatible at all Betta temperatures; better than Monte Carlo for warm Betta setups.
Propagation: Trim 5–8cm tops; replant beside originals. One portion → 10+ stems over 3 trimmings with zero additional cost.
3-layer tank: Frogbit (surface) + Monte Carlo (foreground) + Pearl Weed (mid-ground) = complete planted tank from this catalog.
Planting: 3–5 stems per cluster, 2–3cm apart for stem plant use. Push base 2–3cm into substrate with tweezers. Trim at target height and replant cuttings to multiply.
