All gardeners know that the sun is best when it comes to growing plants, but today we can use electric lighting to garden all year long. Hydroponic gardening with artificial light to imitate the sun’s rays is becoming more and more popular, and there are a lot of choices out there for the type of light hydro growers use. By using electric lighting, you can customize your growing season and encourage plants to fruit and flower when you want them to, without having to depend on good weather.
There are three main types of grow lights that hydroponic gardeners use to grow their plants. These are Compact Fluorescent Lighting (CFL), High-Pressure Sodium (HPS) and Light-Emitting Diode (LED) lights. Each category has its own advantages and disadvantages, with a huge variety of sizes, prices, and quality levels for each. In this article we will first go over some pros and cons for each type of light, then list the best 10 lights out there for hydro growers.
