🧠 Care Tips

• Use full-spectrum light (at least 0.8 W/L or 40–60 PAR at substrate)

• Dose iron-rich micronutrients to keep leaves vividly red

• Add potassium and nitrogen to support healthy leaf development

• CO₂ speeds up growth and intensifies color, but it is not mandatory

• Avoid shading the plant, or red color may fade and lower leaves may fall off
