Buying Guide for Grow Lights

To make an informed purchase about what grow light works best for your gardening needs, consider the following factors.

Size/Number

Choose a light that’s large enough to cover all of the plants in your indoor garden. For one plant, you can get a small light that can move from room to room with your plant. On the other hand, you need a large overhead light if you have rows of plants. You can also purchase several lights if one isn’t enough.

Light

Different plant species and growth stages require different colors and temperatures of light. Warm light helps with fruit and flower production. Cool light, meanwhile, helps seeds grow stems and leaves and greens expand their foliage.

If you have both flowering and leafy plants or don’t know which type of light your plants need, you can find full-spectrum grow lights. These provide a balance of warm and cool lighting to resemble natural sunlight.

Bulb

Most grow lights on the market today use LED bulbs. LED lights are long-lasting and energy-efficient. They also come in different colors and temperatures to suit your lighting needs. These bulbs have almost entirely replaced fluorescent and HID ones.

Fluorescent bulbs are useful for growing plants that require a modest amount of light. However, because their output is fairly weak, you have to put them a few inches from your plants. Though HID bulbs are powerful, even more so than LED ones, they are expensive and energy-inefficient and require special fixtures.


Frequently Asked Questions

How far should my grow lights be from my plants?

It depends on the type of bulb, plant, and light, but a general rule of thumb is two feet away. If you’re using fluorescent bulbs, you can put them a little closer.

Do grow lights work as effectively as natural sunlight?

Grow lights are not as effective as direct sunlight. Plants get the same amount of energy from six hours of sunlight as they do from 13 hours under grow lights. However, for those who don’t have a yard or enough sunlight, grow lights can be a viable alternative. To replicate sunlight as closely as possible, look for a full-spectrum grow light.

How long should I leave my grow lights on?

Grow lights should stay on for eight to 16 hours a day to mimic natural sunlight. The exact number of hours depends on a variety of factors, including what plant you’re growing, how much natural sunlight your plant is getting through a window, and what type of bulb your light is using.
