Best Grow Light: Produce All Year Long

Gardening is a such a therapeutic hobby that I hate cultivating and harvesting can only take place for a specific period of time each year. I’ve recently become interested in how to best grow my own indoor herb garden as a foray into year round freshness, and have explored grow lights as alternatives to natural window lighting.

If you enjoy starting your spring seedlings indoors before planting them outside for the growing season, or are interested in year round produce, then investing in a good grow light may be well worth your while. There are many grow lights and grow light companies available on the current market, but finding the best grow light for your specific needs can be a daunting task. I’ve highlighted 5 of my top picks from my own searches below to give you a good guide to kick off your own.

What is a Grow Light?

A grow light is an artificial light source that you can use indoors to help mimic the natural spectrum of the sun that influences plant growth and production. They are easy to use, plug into your electrical outlets like any other light you may have in your house, and provides varying degrees of brightness to whatever it is you are attempting to grow.

Grow lights are popular with both hobbyist gardeners due to the ability they lend to getting seedlings started, as well as well seasoned horticulturalists who grow a variety of vegetation all year round. They are often offered in a variety of shapes and sizes to fit into almost any space you are attempting to utilize, and also can range in affordability for small personal to business type grows.

How do Grow Lights Work?

Since light is one of the three major things your plants need to thrive and survive, grow lights can be used to mimic the light spectrum of the sun that aides plants in the process of photosynthesis. This process is described through the plants use of light energy which they convert into chemical energy- which thus can be used to feed growth and production.

How Close Should a Grow Light be to Your Plant?

HID: At least 12 inches, more with high wattage
LED: 6 inches or more depending on the width of your grow.
Fluorescent: As close as possible without burning to 12 inches

Grow lights are placed above your plants, usually quite close to the tops of your growing vegetation, in order for photosynthesis to occur. As your plants grow you will need to raise your light to accommodate this growth. A general rule of thumb is to keep your light spaced according to what type of grow light you are utilizing due to differing strength of light and heat each puts out.

Although these types of lights are defined below, keep the following spacing in mind for mature plants. You will want to adjust for seedlings and pay close attention to how much heat is being produce so not to dry out tender plants.

What Spectrums of Light Do Plants Utilize?

Light spectrum can actually be described by the color of each type of light being emitted. This colored light is measured by the temperatures they produce- an important detail since plants prefer varying temperature, or colors, depending on their stages of growth. The best grow lights emit more than one color of light to provide the proper atmosphere within which your plant can grow.

When determining what color light plants grow best in, you really need to look specifically at each plant and the research done surrounding their specific needs. Producing plants, such as tomatoes, grow in more than one phase. The first phase is the growing stage where they leaf out and become more of a plant, rather than a young seedling. Generally the plants within this stage need warmer, or more blue spectrum lights, in order to grow strong and healthy. The second phase beings once they begin to flower and reproduce. To help initiate and support this phase, your plant will prefer cooler temperatures, found within the red to yellow color range. Red lights are also extremely helpful to early growth and should be used with blue for early growth stages.

Types of Grow Lights

Not all grow lights are made the same, however. Some emit a wider light spectrum than others, some produce various temperature fluctuations, and some are more specific to certain kinds of plants. When making your decision before making a purchase you may want to do a little research concerning your particular crop and it specific needs. We’ve provided a rundown of what is available for you to utilize in order for you to be able to make an informed comparison, and better understand what products are most widely offered.

High Intensity Discharge (HID)

These are a popular light amongst experienced growers due to their high light output. These fall into three categories, Metal Halide (MH), High Pressure Sodium (HPS), and Ceramic Metal Halide (CMH). Each is favored for various reasons, but a simple explanation is that MH lights produce more light within the blue range of the spectrum, HPS produce more red and orange, and CMH provide a balanced mix of blue, red, and orange.

Fluorescent

Fluorescent lighting is popular for early growth stages, and are also considered highly energy efficient. They also don’t put out a lot of radiant heat, making them ideal for smaller grow areas, especially since they are available in a wide range of sizes. They do come in two different types: a high output (HO), and very high output (VHO). The technology behind the two is exactly the same, it’s just that the VHO put out more light, and therefore also more radiant heat.

Light Emitting Diode (LED)

Not only are LED lights highly efficient energy wise, they also put out very little heat and can be used in very small spaces. Plus, the diodes are placed within light panels, means that each individual diode can be customized to put out varying spectrums of light. This can result in a panel that is able to produce light across the needed spectrum at all stages of vegetative growth.

Plasma

This is a relatively new light technology that is similar to ceramic metal halide bulbs, but is considered much more efficient and with an even wider range of light spectrum.

What Is the Best Grow Light For Your Vegetation

As explained above there are a few details you should be aware of before deciding which grow light system is best for you. When narrowing down your choices, you may want to take into consideration the following questions:
How much space do you have for your grow?

If you plan on using a larger space, lights that can physically span the areas you need to cover without being placed too high above your crop to be effective are the ones you will want to focus on HID choices are often chosen in these types of situations. Smaller spaces can more easily accommodate LED and Fluorescent lights that produce less heat- and can be more safely placed closer to your plants.

What crops are you planning on growing?

As mentioned earlier, different types of plants may have different phases of growth and therefore their needs will vary from one another. Know what plants you plan on growing in advance to better utilize the light that you decide upon.

What stages of plant growth will you need light for?

Are you planning on starting seeds, cuttings, or seedling only? Are you wanting mature plants to produce? Are you simply supporting non-producing greenery? Or are you looking to support a whole growth system from sprout to harvest? Since certain spectrums of light are supportive of these many different scenarios, be aware of your plans in advance in order chose the best indoor plant light.

Their fluorescent-grow light system comes in your choice of sizes to meet the needs of a smaller, more personal garden, as well as a large scale grow.

Fluorescent bulbs are more specific to the blue range of the light spectrum and are used mostly for germination and seedling starts. Although red wavelengths are also available, fluorescents work best with other lighting sources for late-stage growth and production. Since they do not put off a large amount of heat, these bulbs are popular for smaller, more enclosed spaces, and since this particular system can be mounted vertically, horizontally, or overhead, it is ideal for getting light into harder to reach spaces.

This is a great system for anyone looking to get started with a crop to build strong, healthy plants and promote mature growth. The adjustability of how close you can place the light is exactly what young plants need to be exposed to as much light as possible for healthy initial growth. The bright blue light provides the correct temperatures needed for quick seedling growth so you can have a more productive crop later on. The red spectrum that is also present in the fluorescent helps with the later stages of growth as well, although it is suggested that you either replace this system with a red/orange light as the plants mature or add an additional light to the entire process.
