Help your houseplants, seedlings, and herbs thrive by giving them the right supplemental lighting. Sure, all plants need light, but the amount they need can vary quite a bit. A space with a sunny window may be all your low-light houseplants need to do just fine, but other indoor plants demand brighter, more consistent amounts of light to grow properly. For example, if you're starting veggie seedlings for your spring garden, coaxing a blooming houseplant to produce flowers, or even raising fresh herbs on your kitchen countertop , the right grow light is your friend.

The Best Grow Lights for Your Indoor Plants

Make a donation. Once the preserve of professional growers, lighting systems can now be used to good effect in the home and greenhouse to grow plants.

They can be inexpensive and do not need an in-depth understanding of the science and mechanics, so anyone wishing to experiment with growing plants under artificial lighting can have a go.

Many plants grow well in a bright location in the home. However, the use of artificial light can be of further benefit in the following circumstances;.

Domestic light bulbs are unsuitable for growing plants as the light intensity is not enough and they are less energy efficient. For these reasons alone, it is best to choose specialised horticultural lighting. Readily available from horticultural suppliers, T5 HO fluorescent tubes have the following advantages that make them the current top choice:. They benefit from low operating temperatures and are longer lasting and more energy efficient than T5 HO fluorescents.

At this point in their development, however, they can still be more expensive than T5 HO fluorescents to install. Specialist light meters may also be required to measure the light output of these systems, which can add to the expense of the set up.

HID High Intensity Discharge lights, which include metal halide and high-pressure sodium systems, give off a tremendous amount of heat. This makes them less useful in the home as extraction equipment is necessary to remove the hot air.

The bulbs cannot be placed close to the plants because of the potential damage from the heat generated, meaning more growing space is required. Plants absorb mostly blue and red light think of the colours present in a rainbow, plants use two particularly in order to grow and flower. Blue light generally stimulates growth, while red light is important for growth and flower production.

T5 HO tubes are available that produce colour values based on the Kelvin scale K. Tubes with a K value tend to produce light with a reddish tone, while those with a value of K produce bluish light.

If using fluorescent tubes to grow flowering plants, a combination of red and blue tubes will provide the best light for growth and flowering. There are a variety of kits available which include an electronic ballast that starts up the tubes and reflectors to direct the light downwards onto the plants. These benefit from predominantly blue light to promote good growth and compact plants.

The T5 HO tubes should be placed around 60cm 2ft above the seedlings for around 16 hours a day. Tomatoes for example can be started earlier in the year under lights when natural daylight is still too weak. This enables plants to be more advanced by the time they are planted in their final positions in the greenhouse or border. Again adjustments can be made regarding light intensity requirements.

See: 'Problems' below. Phalaenopsis moth orchids and African violets Streptocarpus syn Saintpaulia can be grown under lighting very successfully and are tolerant of a variety of lighting conditions. Leaves should be a mid-green. Plants from naturally low-light habitats, such as ferns and many of the smaller tropical foliage houseplants that in nature inhabit shady forest floors, can be kept healthy long-term under simple artificial lighting.

Use an aquarium tank as a terrarium for these plants and position the T5 HO lights in the hood.Not only will this provide a decorative focus in a room but the terrarium will help retain the high humidity which these plants love.

Different plants will vary in their lighting requirements to grow and flower well. It is best to research the light requirements of your chosen plants and ensure the output of the lighting system is sufficient to ensure success. This can be done by carefully measuring the intensity and quality of light provided using a quantum light meter.

Generally a mid-green colouration to the foliage indicates the plants are receiving the correct amount of light. However, there are a number of problems that can be encountered and rectified. Seedlings that take on a bleached appearance or become stunted after growing under lights.

Similarly, yellow-green foliage on plants nearest the tubes can indicate the light intensity is too high for the plant in that position. The intensity of light can be lowered by:. This can also create problems with plant development, but balancing the number of red and blue tubes should correct the following problems:.

Why use artificial lighting Many plants grow well in a bright location in the home. However, the use of artificial light can be of further benefit in the following circumstances; For plants that need more intense light levels than are naturally provided indoors in the UK, especially during the short winter days For starting seedlings early in the year, rather than waiting for natural light levels to increase, resulting in stronger, more advanced young plants to plant out in spring For growing plants in a dark corner, windowless garage, where natural light would be too low For creating a decorative feature in a room, such as an illuminated terrarium full of foliage plants.

What artificial lights to use in the home Domestic light bulbs are unsuitable for growing plants as the light intensity is not enough and they are less energy efficient.

Here is a summary of the options available for the home. T5 High Output HO fluorescent tubes Readily available from horticultural suppliers, T5 HO fluorescent tubes have the following advantages that make them the current top choice: The intensity of light produced is generally strong enough to enable good growth and flowering when positioned correctly They are long-lasting about 20, hours They are relatively inexpensive They are generally economical to run, but not as energy efficient as LED Light Emitting Diodes lighting They give off comparatively little heat making them safe to place close to plants Other options LED Light Emitting Diode horticultural lighting is a viable alternative for indoor use.

How to use artificial lights in the home Plants absorb mostly blue and red light think of the colours present in a rainbow, plants use two particularly in order to grow and flower. Simple lighting system There are a variety of kits available which include an electronic ballast that starts up the tubes and reflectors to direct the light downwards onto the plants.

In the home a basic set-up could be a unit containing two 60cm 2ft T5 HO fluorescent tubes suspended approximately 60cm above for example, a small group of houseplants, or crops such as leaf salads for fresh leaves during the winter months The lights can be on for around 16 hours a day Plants often require different light intensities. The foliage colour is a good indicator to determine whether the plants are receiving enough light and the intensity can be adjusted to suit them See: 'Problems' below Seedlings These benefit from predominantly blue light to promote good growth and compact plants.

See: 'Problems' below Plant collections Phalaenopsis moth orchids and African violets Streptocarpus syn Saintpaulia can be grown under lighting very successfully and are tolerant of a variety of lighting conditions.

Other plant genera Different plants will vary in their lighting requirements to grow and flower well.Problems Generally a mid-green colouration to the foliage indicates the plants are receiving the correct amount of light. Too much light: Seedlings that take on a bleached appearance or become stunted after growing under lights.

The intensity of light can be lowered by: Reducing the number of tubes Repositioning the tubes further away from the plants Reducing the number of hours the lights are on photoperiod Too little light: Plants grow poorly and foliage is dark green.

This can be corrected by: Increasing the light intensity by moving the plants closer to the tubes increasing the number of hours the lights are on Increasing the number of tubes Too much blue or red light: This can also create problems with plant development, but balancing the number of red and blue tubes should correct the following problems: Too much blue light with very little or no red light, results in stunted plants with dark green leaves, thick stems and few flowers Too much red or far-red light promotes stem elongation and tall spindly growth.

Artificial Grow Lights vs The Sunlight for Plants

Of course, sunlight is undoubtedly the cheapest source of light for growing plants but it is not always available. With an indoor grow light to grow your own , it is possible to gain control over your plants and grow effectively all year round! The first factor is to choose the colour of light required, whether you need a warm or cool light source. The temperature of light is expressed in degrees Kelvin and is known as the correlated colour temperature or CCT, and relates to actual thermal temperature. High intensity discharge HID lamps and fluorescent light sources all have CCT ratings and this indicates how warm or cool the light source is, for instance a lamp with a CCT of Kelvin is considered warm, Kelvin is considered neutral and Kelvin is considered cool. Ideal for the rapid growth phase of plants. Greatly enhances all round plant growth when used with super high output, high pressure sodium or 3K warm metal halide lamps.

Always position a grow light above the plant. This replicates sunlight. Plants will naturally start to lean towards a light source, so above is always the best.

Finding the Perfect Light: An Indoor Plant Light Guide

The following excerpt from The New Plant Parent , used with permission from Abrams Image, explores the importance of understanding light and offers advice on how to better gauge light in your indoor living spaces. Misunderstanding light intensity is the cause of most disappointing experiences when it comes to house plants. But what about the job that plants need to do? Their job of growing and living is powered by light!

Until scientists invent convenient little mini Suns we can keep inside our homes, our plants will need to rely on artificial light. Fortunately, those sources of illumination have come a long way in terms of efficiency and efficacy.

How to use Grow Lights for Indoor Plants

Most plants need some light in order to grow, but shade-loving plants can easily get by with indirect light, or even artificial light from regular light bulbs. Chinese evergreen is a durable plant that tolerates a fair amount of neglect. Mature plants produce lovely, white blooms that resemble calla lilies. Chinese evergreen thrives in very low light or under a regular bulb, and too much light will scorch the leaves. Choose a variety with darker leaves, as variegated types with cream or silver markings require a bit more light. It also withstands a dry environment and thrives with sporadic watering.

Light Guide

The indoor plants lighting guide provides information about the light requirements needed for plants that's vital for them to survive and grow well.Various conditions are essential factors which have to be provided for a house plants survival, including water, humidity, a suitable growing medium, correct temperatures and of course "light". Full Sun: Most house plants do not like full sun and many of them will become very damaged or will not survive very long when they receive too much direct sunlight. The only plants that enjoy summer sun is desert cacti, and succulents can tolerate a lot of sun succulents seem to prefer some sun and bright conditions. Full sun is experienced from a south facing window.

Lighting for growing my plants

After considering the direction, is there anything blocking the outside of your window? Consider these general tips in regards to houseplants and light levels:. You can pretty much put it anywhere, as they can thrive in almost any light. The big thing to look out for is overwatering, so make sure to let the top inch of soil dry out between waterings. I have a spider plant that did super well at my mother in laws and now at my house it is browsing and losing all of its leaves.

Will house plants grow under normal LED lights?

Succulents and cacti need a certain amount of sunlight to thrive. Plants grow by absorbing light and turning it into energy through the process of photosynthesis. Providing adequate light, when growing succulents indoors, can be particularly challenging and may need some experimentation on your part. If these plants do not receive adequate light, they do not grow properly. Overtime, succulents that do not receive enough light become weak, distorted and discolored. When not exposed to adequate light they start stretching out to look for the sun.

Even houseplants often require different levels of light. The succulents on the left require more than 4 hours of direct light. The fern on the right would burn under such intense light. To us, both pictures appear "bright.
