Horticultural indoor farming is growing due to the increasing demand for food, flowers and medicinal plants. With this demand comes an increase in research into the impact of light sources on yield. Sylvania continues to incorporate this knowledge to develop more efficient and cost-effective lighting solutions which extend the growing seasons of the plants and increase the yield and quality of the crop.

Gro-Lux® LED Interlight has been developed so that additional light can penetrate deeper into plant foliage to increase their growth and yield in horticultural facilities. For high-wire cultivation natural sunlight or toplighting alone is not enough to obtain the best performance from a plant. Shadowing from the top leaves of the plant can block the light for the leaves below. By using supplementary interlights, all leaves of the plant obtain the light energy they need, thus increasing growth rates and yield.
