The type of grow light used for microgreens depends on the specific needs of the plants and the stage of growth. However, in general, most microgreens are grown using LED grow lights or fluorescent grow lights.
LED grow lights are a popular choice for microgreens because they are energy-efficient, emit little heat, and can be customized to provide the exact spectrum of light that the plants need. They also have a long lifespan, which means they require less maintenance and replacement.
Fluorescent grow lights, such as T5 or T8, are also a good option for microgreens because they provide a wide spectrum of light and emit very little heat. They are also energy-efficient and have a long lifespan. They are less expensive than LED grow lights and it’s easy to find them.
It’s important to note that microgreens require a significant amount of light to grow properly, so it’s essential to provide them with enough light for the entire growth cycle. Additionally, a good practice is to change the lights at least once a year as the light intensity decreases over time.
In general, it’s recommended to provide microgreens with at least 20-30 watts of light per square foot of growing space. Additionally, it’s important to provide the plants with a consistent light schedule, with at least 14-16 hours of light per day.
