By mastering the balance between light intensity and temperature control, you can cultivate robust microgreens that flourish beautifully, whether indoors or outdoors.

Insufficient or Excessive Light

Insufficient light exposure can result in leggy growth for your microgreens, rendering them weak and lacking in nutrition. On the other hand, too much light can stress the plants, leading to leaf burn and stunted development.

It is vital to monitor both the duration and intensity of light. This helps microgreens thrive. They will reach their full nutritional potential.

To cultivate healthy microgreens effectively, aim for a bright yet indirect light source for about 12 to 16 hours each day during the seedling stage. As they mature, slightly reducing this duration can be beneficial, allowing for around 10 to 12 hours of light.

If you notice yellowing leaves or excessive stretching toward the light, it’s a clear sign of deficiency. You can rectify this by increasing exposure time or intensity. If the leaves become crispy or develop dark spots, it may indicate overexposure. In that case, you should reduce the light duration or relocate them to a less intense light setup.
