Buying Guide for Grow Lights
To make an informed purchase about what grow light works best for your gardening needs, consider the following factors.
Grow Light Coverage
Grow lights typically give you measurements for how much vegetative and flowering coverage they offer. Be sure to choose a light that matches the amount of light and type of coverage you need for your indoor growing area, grow tent, or plant wall.
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.
Wattage
A grow light’s wattage determines how many lumens of light it produces in your grow room. Different plants require different amounts of light, so don’t just choose the light with the highest wattage to ensure optimal plant growth. Instead, match the wattage to the plants you’re growing. For example, if you’re growing tomatoes, choose a grower that offers about 32 watts of light per square foot.
Adjustability
Several features of your LED grow light should be adjustable.
- Brightness: In addition to color adjustability, LED growers usually have knobs for adjusting the brightness of their light bulbs to ensure optimal light intensity.
- Color: Plants need a different color light for every step of their growing cycle. The best grow lights offer red lights, blue lights, and white light color options.
- Proximity: You can also adjust how close the lights are to your plants by lengthening or shortening the rope or chain they’re hanging from.
Other Ways To Help Indoor Plants Grow
LED grow lights are a great way to help indoor, clean-air plants grow, but there are various other ways to help your indoor plants reach their full potential. Here are important steps our team found that you can take to help your houseplants grow and increase their versatility.
Be Aware of Light Conditions
While LED grow lights help, try buying plants that most closely match the light situation in your household. For example, if you have small windows or little natural light, focus more on plants that can thrive with minimal sunlight. Also, you should be aware of how well a particular plant does in terms of distance from the window and sun direction to help ensure it will grow to its maximum potential.
Water With Caution
Everyone knows plants need water, but overwatering can also become an issue if you’re not careful. To help your plants grow to their peak, check the soil carefully before watering. Put your finger 2 inches into the soil to see the moisture level. If it’s not fully dry, you may want to hold off on watering it.
Pay Attention to Pests
Pests can be a significant nuisance to plant growth. To help ensure your plants are being infested, check them regularly for bugs such as aphids, gnats, and whiteflies and treat them immediately if you see them.
Avoid Winter Fertilizing
In the winter, plants become dormant and do not need fertilization. Fertilize only in the spring and summer months to ensure proper growth.
Be Mindful of the Pot
Choosing the proper plant container for your plants is an important factor when it comes to growth. The first step is making sure your plant pot has holes for drainage. Additionally, you should also purchase a container that’s at least 1 inch larger in diameter than your plant’s root mass. When a plant begins to outgrow its container, it’s crucial to re-plant with a larger container to help it continue to grow properly.
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.
