How to choose the best grow light for your indoor garden
Grow lights are a cost-effective and convenient way to provide artificial sunlight for your houseplants, indoor herb gardens, or seedlings.
Although the lights and all-inclusive sets are simple to use, there is a wide range of lamps available.
Each product has its strengths and weaknesses, from fluorescent tubes to LED strips. A basic understanding of the features will help you make an informed purchase decision.
Let’s get into the details.
Why Grow Lights?
To grow in a healthy way, plants must be able to harness and convert sunlight’s energy. Photosynthesis is the process by which plants get the energy they need to grow vigorously.
Grow lights are an artificial source of luminous energy that provides the various frequencies of the spectrum of color needed by plants throughout their entire development, from seedlings to fruit sets.
The Electromagnetic Spectrum
All frequencies within the electromagnetic spectrum are emitted by the sun, including visible light, violet, indigo, and blue.
These frequencies are what plants require for normal development.
- Blue– Blue is the initial color that plants absorb and is vital at the vegetative stage.
- Purple– Although purple is not an effective energy source for photosynthesis, it helps in the vegetative stage.
- Green– While primarily reflected, small amounts of green are retained and can be used to convert energy.
- Yellow– Yellow is the most effective color for photosynthesis.
- Red– For blooms to develop, red is required in the mature flowering stage. It is best to combine blue with red. In the vegetative stage, red should not be used alone.
- White-White is a combination of all visible colors and can be used for all stages of a plant’s growth.
For seedlings and leafy vegetables, you will need to use higher-specified bulbs in the blue spectrum.
However, if you want your plants to bloom and bear fruit, then you will need low-spectrum red colors.
You can also make it easy. To satisfy all stages of your cultivation, you can use a white, full-spectrum bulb.
Different types of bulbs
Indoor growing has been made possible by a variety of special electric bulbs. These are the most popular:
- Compact fluorescent lamps (CFL)
- Fluorescent tubes
- High-pressure sodium vapor (HPS).
- Light-emitting diodes (LED)
- Metal-halide (MH)
The most common and easiest to obtain for the average home gardener who wants to plant a few seed trays, are fluorescents and LEDs.
Compact Fluorescent Lamps
Compact CFLs are a great choice for small spaces and can be used in any regular, incandescent bulb fixture.
However, because of their small size, light distribution from one CFL is very limited and usually covers a small area.
Fluorescent tubes are available in different lengths. They provide better coverage than CFLs and can be used to cover several standard seedling trays.
These tubes fit in a standard fluorescent fixture. However, they are not compatible with regular household ones.
High-Pressure Sodium Vapor
High-pressure sodium-vapor lamps are used to provide light in the red and yellow spectrums. They are usually only used in the flowering stage in order to encourage bloom set.
These bulbs are used by large-scale growers to replace the metal halide bulb after plants have reached their vegetative stage. These bulbs are not used by most home growers.
Light Emitting Diode
LEDs are available in small strips or bulbs and have the best long-term economics. LEDs are more luminescent than fluorescents and use half the electricity. They also produce less heat, last five times as long, and can last five times as long.
The typical LED bulb for your home is not designed to be used on plants. You can choose from a combination, full-spectrum, or isolated spectrum bulb that suits your needs.
Metal halide bulbs emit cool, blue-green colors and are best suited for larger operations that can run at full power.
Although initial prices are comparable to LEDs, MHs are much more expensive and can be used indoors only.
The Kelvin Scale
The Kelvin scale is a range of 1,000 to 10,000 and represents a color’s temperature. The Kelvin value indicates how close a lamp’s shade is to natural sunlight. The capital letter K indicates the Kelvin degree.
Ratings below 3500K are more likely to have a warm color, with an amber tint. Ratings higher than this get you closer to a pure or cool white color.
A rating of 6500K is ideal for leafy vegetative growth. However, to produce flowers and fruits, plants need to be exposed to warm hues for approximately 3000K.
Lumens vs. Watts
Wattage is used to indicate a bulb’s brightness. A 100-watt bulb, for example, would produce one-and-a-half times as much luminosity than a 40-watt bulb.
Without enough sunlight, plants can become sluggish and lose their ability to grow.
However, wattage has become a poor indicator of brightness with the introduction of energy-efficient bulbs. Wattage is simply the power required to make a lamp bright. It can now be indicated using lumens.
An LED with 1,600 lumens is an example of an energy-efficient LED. It has the same brightness as a 100-watt bulb but consumes only 22 watts. A comparable bright CFL bulb will consume around 26 watts.
The basic principle is that the brighter the light, the higher the lumen count. A minimum of 2,000 lumens per square foot is sufficient for seedlings. Flowering crops may require up to 10,000 lumens per sq foot.
Consider a Kit or Light Stand
Be prepared to do some creative rigging if you are buying light bulbs and not a stand or kit.
To accommodate growing plants, lamps must be adjusted in height. It is best to allow between two and five inches for the lamp and the top of the leafy growth.
Some bulbs come with an integrated deflector that directs energy to the plants. Others don’t. You may need to buy a fixture to direct the rays where you need them.
It is much simpler to buy a kit or light stand.
Most kits and stands include adjustable lamp fixtures that can be adjusted to allow for plants’ growth. Sometimes, they also include useful accessories.
These accessories can make your indoor garden a success.
- Capillary Mat – A capillary mat gives seedlings steady, gentle watering at the bottom so they are not disturbed by strong water flow.
- Reservoir base is required to use a capillary floor mat. The mat is placed on the shelf and the water is added to it. The mat absorbs the water and then wicks moisture to the bottom of the trays.
- The timer is a timer that allows plants to get optimal sunlight exposure without the need to turn them on or off manually.
- Modular and stacking – These allow you to add vertical tiers without having to have a larger footprint.
Tips to Grow Strong Seedlings
These tips will help you get the most out of your indoor garden.
1. Start seedlings indoors with simple plants that are easy and quick to germinate.
For beginners, basil, coleus, and cucumbers are good options.
2. For starting seeds, use a high-quality, sterilized soil. This is essential to avoid fungal and bacterial infections in tender sprouts.
Gardener’s Supply offers horticultural-grade coconut coir that can be ordered via Amazon. This is great for seedling production and germination.
3. Even for cool-weather crops such as lettuce and spinach, most seeds require warm soil temperatures to germinate.
Temperatures of 70-75 degrees F for several hours each day should be sufficient to maintain soil temperature.
An ordinary kitchen thermometer will work fine for checking the soil temperature. You can also purchase a horticultural thermometer, such as, available through Amazon.
Maintain soil temperatures within the recommended range on the seed packet. If necessary, heat mats can be used in unheated garages or cool cellars. This 9×19.5-inch mat by Hydrofarm, available via Amazon, fits standard seed trays.
4. Also, keep the lamps within 2 to 5 inches of the seedlings. As plants grow in size, raise the fixture.
5. You should also monitor the air circulation. Tender shoots can be affected by heat stress if your setup produces temperatures above 80 degrees F. If necessary, you can use a fan to move the air gently.
6. Use a gentle hand to water the soil. Water the soil well before planting to ensure that delicate seeds don’t get damaged by strong water flows. Use a spray bottle to keep the soil moist, or let trays soak up the water from the bottom.
7. When seedlings are fully grown, use a small knife to separate any clumps. Then, place the tray in a container until you are ready for transplant.
Let There Be Light!
Indoor gardening is easier when you have to grow lights. They allow you to grow plants in any season and in any climate.
You can start seedlings, grow herbs, and greens, or pamper your plants with lamps that mimic natural sunlight. There are models to suit almost any setting.
It’s easy to use and affordable, and you’ll love seeing your plants thrive under their nurturing glow.
