Codium prefers a bright place, with direct sunlight in the morning or evening. In summer, the plant should be placed on the south windowsill. Good lighting contributes to the brighter color of the leaves. Growth will slow down in the dark, and most importantly, the color will be less rich, or the leaves will stay green. It likes heat, so the temperature should not be less than 16-18 degrees.
The size of the plant varies.
