What are lighting precautions regarding hydroponic gardening?

Check for exposed electrical wires, and worn cords. Keep the cord's path to the socket out of the way of traffic patterns where family and pets may trip over them. Keep cords away from heat and light sources. Run the lights 24/7 only for seedlings. And in that case, use the low heat of fluorescent or LED grow lights. For other life stages of plants, use a timer to run the light 18 hours and then to shut it off for 6. Regularly check for, and repair, cracks and tears in reservoirs and tanks. Keep the electrical ballast more than splashing distance away.

LED lighting is said to be best for hydroponic gardening.It consume very small power compared to other grow lights. They do not generate much heat. The LED bulbs will last for years and they can be adjusted for the light spectrum needed, whether budding or growth.
