You should plan your system on having at least 14 to 16 hours of bright artificial light, followed by 10 to 12 hours of darkness every day. The darkness is just as important as the light—just like animals, plants need time to rest and-metabolize.

What color of light is best for plant growth? Red and blue light are most effective for plant growth, while green has minimal effect. UV light can damage plants, causing leaves to burn. Greenhouse growers use supplemental light for optimal plantgrowth.

Can you replace halogen bulbs with LED? Yes, in many cases, you can simply replace your bulbs separately, one by one. Replacing your existing incandescent or halogen bulbs with durable LED bulbs offers numerous benefits. You enjoy an even better light performance and benefit from very low energy-consumption.
