  • The intensity of light required varies depending on the plant’s growth stage.
  • Seedlings and young plants require lower light intensity of around 150-300 µmol/m²/s.
  • Mature plants require higher light intensity of around 600-1000 µmol/m²/s.
  • Too much light intensity can lead to plant stress, while too little intensity can lead to reduced growth and yield.

Duration Of Light

The duration of light is crucial when selecting hydroponic lighting. It is essential to provide the plants with adequate light for optimal growth and development, but too much light can be harmful. Here are some key points to consider:

  • Most plants require 12-16 hours of light per day for optimal growth and development.
  • Some plants, like leafy greens, can tolerate less light, while others, like tomatoes and peppers, require more light.
  • Providing plants with too much light can lead to stress and reduced yield.
  • It is crucial to maintain a consistent light/dark cycle for the plants to maintain healthy growth.

Selecting the right hydroponic lighting is crucial for the success of an indoor hydroponic garden. Consider the light spectrum, intensity, and duration when selecting hydroponic lighting to ensure optimal plant growth, development, and yield. With the right hydroponic lighting setup, you can enjoy fresh and healthy produce year-round.
