Avoid light burn and adjust intensity: yellow tips and bleached areas are warning signs — gradually increase intensity, use hand test and light meter.
Light burn is characterised by yellow/white tips, bleached areas, curled leaves. Prevention: Gradual increase in intensity, hand test (30cm distance), temperature monitoring. Treatment: Immediate increase in spacing, leave damaged leaves. Optimum distances: CFL 15-30cm, LED 30-60cm, HPS 60-100cm.
Light burn is characterized by yellowed or scorched leaf tips and edges, often accompanied by general discoloration of the leaves. Look for any unusual leaf texture or shape, which may indicate stress.
Light intensity can be adjusted by changing the distance between the light source and the plants, using dimmable bulbs, or switching to less intense light sources. Start with a distance of 30–60 cm and gradually reduce the intensity if you notice signs of stress.
LED bulbs are ideal because they generate less heat and offer adjustable brightness. CFL bulbs are also a good option for growing plants, as they are less intense and reduce the risk of light burn.
