Gardeners know that the sun is best when it comes to growing plants from seed to fruit or flower, 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 lights that hydroponic gardeners use to grow their plants. These are Compact Fluorescent Lighting (CFL); High Intensity Discharge (HID), which includes both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs; 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.
- Pros: Full spectrum, can be used for both flowering and vegetative growth, very powerful lights.
- Cons: Bulbs wear out quickly, uses a lot of electricity, high heat output requires fans.
- Pros: Low heat, relatively energy efficient, inexpensive, good for green leaf plants like lettuce, spinach and herbs.
- Cons: Not good for flowering or fruit producing plants, not full spectrum nor very powerful.
- Pros: Very low heat, red and blue LEDs can be combined to create full spectrum or partial spectrum lighting, bulbs last a very long time, customizable for small or large gardens, very energy efficient
- Cons: Expensive to purchase up front although they save money on energy costs.
In this article I have listed my top five picks for all three types of grow lights. Items 1-5 are High Pressure Sodium, items 6-10 are Fluorescent and items 11-15 are LED lights. You will find the best quality lights in this list as well as something for every budgetand gardensof all sizes.

High Intensity Discharge (HID) Lighting Systems
HID lights are large bulbs that are filled with gas, which is ignited when electricity is run through the bulb. This creates a bright light and also puts out a lot of heat. HID bulbs come in two types for hydroponic gardening, and are categorized by the type of gas used in the bulb. Metal Halide bulbs has a more blue light spectrum are usually used for vegetative growth, while High Pressure Sodium bulbs have a more red light spectrum are used for flowering or fruiting. HID bulbs wear out quickly and must be replaced yearly for full growth potential in your garden. HID systems also include a ballast to power the bulb as well as a reflector or hood to maximize your light coverage.
