For example, DLI can influence the root and shoot growth of seedlings and cuttings, impact characteristics like branching, flower number, and stem thickness, as well as speed up or slow down production.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">Different plant species have different light requirements at each stage of development. Keep in mind that since DLI is dependent on both photoperiod and intensity, when both light levels and day length are reduced during the winter period the DLI will decrease considerably. Under such conditions, supplemental lighting not only needs to be at the right intensity and photoperiod but also attention to light quality may be of importance to ensure that plant quality is achieved.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<h4><b><span data-contrast=\"none\">Importance of Light Quality<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/h4>\n<p><span data-contrast=\"none\">Light gives plants the energy they need for photosynthesis, which converts that light energy into sugars to fuel growth and development. In addition to the quantity (intensity) and duration (photoperiod) of light you provide to plants, the quality of the light (spectrum) is also important. Broad-spectrum LEDs are available that offer an extensive variety of wavelength combinations to meet specific growth goals. Such LEDs can be controlled to deliver the ideal light to suit the application, such as supplementing the natural light plants receive in a greenhouse or providing a balanced broad spectrum that replaces natural sunlight in a sole-source indoor growing environment.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">The light spectra can also be tuned to individual crop needs. For example, blue light is associated with decreasing plant stretching, green light is known to reach further into the canopy and can prevent inner leaves from yellowing, red light is known to stimulate photosynthesis, while far red is known to help promote growth and flowering. This is just a small sampling of what controlling and balancing the different wavelengths of light can achieve.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<h4><b><span data-contrast=\"none\">Light Conditions in a Greenhouse<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/h4>\n<p><span data-contrast=\"none\">Light can be one of the most limiting factors for crops, and this is especially true for high-light crops in a greenhouse, where seasonal variations and limitations may inhibit crop productivity.

Together, these need to provide a consistent DLI for your crops year-round to ensure consistent production 365 days per year. When controlling the supplemental lighting in your greenhouse, you need to consider the natural light levels in your facility, the geographic region, the season, the time of day, the light transmission factor coming through the glass, and even the shade cast from the structure. There are many things you can\u2019t control when it comes to greenhouse lighting, but what you do have the opportunity to control is your supplemental lighting, such as using intelligent LEDs with predictive lighting control technology.
