Growlight LED 120 cm - Hobby

The light intensity required for microgreens to grow properly is typically measured in micromoles of photons per square meter per second (μmol m^-2 s^-1), rather than millimoles. This measurement quantifies the amount of light energy available for photosynthesis, which is crucial for plant growth and development.

The optimal light intensity for different types of microgreens can vary,

Light Requirement: Microgreens that originate from shaded environments or those that are more tolerant of lower light levels may require around 100-200 μmol m^-2 s^-1 of light for proper growth.

It's important to note that the exact light requirement can also depend on factors such as the specific species of microgreen, growth stage, and environmental conditions (e.g., temperature, humidity). Growers often use light meters or sensors to measure and adjust light levels to ensure that microgreens receive the optimal amount of light for their growth needs.
