Insufficient lighting

Symptoms

The plants are fragile and delicate, the green leaves pale or yellowish, the rods small. Rosette plants have small leaves on Maling Rods. The rod plants have few leaves, the internoid spaces are very large. Close to the light source, the vegetation is vigorous and dense while the lower part of the stem is sometimes completely bare. We see algae appear.

Cause (s)

Lamps too weak or too few, devoid of reflector, too old tubes, insufficient lighting time (less than 12 hours per day). Algae or limestone deposit on the cover. Too large density of plants on the surface.

Remedy

Provide adequate lighting.
