Light requirement during different seasons
In general, lettuce requires a moderate amount of light throughout the year. However, the amount of light required during different seasons may vary slightly.
Spring: In the spring months, you will generally want to grow your lettuce under grow lights for around 8 hours per day. This is because there is not as much sunlight available during this time of year as in other seasons. Lettuce varieties that grow well in cooler conditions, such as romaine and leafy greens, may perform best during this time. Also, ensure that your grow lights are positioned to provide the right light to grow healthy and thriving lettuce plants.
Summer: Lettuce varieties In the summer months, you may need to adjust your grow lights to ensure that your lettuce receives enough sunlight. Generally, you should aim for around 9-10 hours of grow light daily during the summer for optimal growth and yields. This is because, in the warmer months, lettuce plants may grow more quickly and require a higher amount of light to thrive. Lettuce varieties such as butterhead, romaine, and leafy greens may grow best during this season.
Fall: Lettuce varieties In the fall months, you should aim for 6-7 hours of grow light per day for your lettuce plants. During this time of year, the days grow shorter and less sunlight is available. As such, lettuce plants may not grow as quickly during this time of year and may require slightly lower levels of grow light to grow well. Lettuce varieties that grow well under lower light levels, such as butterhead and romaine, may be best suited for fall lettuce production.
Winter: During winter, you will generally want to provide your lettuce plants with around 8 hours of grow light per day. This is because lettuce plants grow more slowly during winter and typically require higher light levels to grow well. In addition, you may want to consider using grow lights that provide warmer light frequencies, such as red or orange wavelengths, for this season to promote healthy growth and development. Lettuce varieties that grow well under cooler light conditions, such as leafy greens and romaine, may be best suited for winter lettuce production.
