Light intensity is a measure of light energy hitting the plant surface and is also very important to plant health. For traditional interior lighting applications, light intensity is discussed in terms of foot-candles of light energy. And, for most tropical foliage plantings foot-candles of light energy hitting the foliage, is sufficient. LiveWall, LLC has developed a plant selection and pairing guide for indoor plants based upon their lighting and water needs, and growth habit. This LiveWall design guide should be consulted for the correct light intensity for the type of plants that one intends to use.

How to Choose the Best Plant Grow Lights for Your Indoor Garden

In actual fact, the opposite is true! At the beginning of my indoor plant journey, I really had no idea about plants. I just found one that caught my eye and stuck it in the corner.

Giving plants as much light as possible can go against our plans to spruce up that bare corner or that dark room that needs some life added. If grow lights are new to you, read on to learn specific advice on how to use grow lights for indoor plants. Plants use light differently to humans. Where we use light to see, plants use light as energy to photosynthesise and grow.A grow light is specifically designed to give plants the right type of light in the spectrum that they need for life.

With a grow light the spectrum of light they use, how powerful they are, their colours and even the design or shape of the light itself all go towards providing a plant with the maximum amount of energy they need to grow. Some grow lights may appear to look similar to regular household globes. But keep in mind that how our eyes perceive light is very different to how plants perceive and use it.

How long a grow light should be on for really depends on a few factors. The light you use should come with specific instructions. Grow lights need to be quite close and unobstructed to a plant for it to have any effect. And just like indoor plants can start to lean towards windows when looking for more light, they can lean towards grow lights too! In general, plants will need to be within a couple feet of a grow light to get any benefits. The closer a light is to the plant, the higher the light intensity is.

Generally, the closer a light is to a plant, the less width it covers. You may need to have the grow light further away to cover multiple plants. You may have noticed that grow lights come in all different colours. This is because plants use different light waves for different uses, such as flowering, fruiting or general leafy growth.

A full spectrum grow light will provide plants with the full range of light they need and if you find a white one, they look much more appealing that the coloured ones!

A full spectrum grow light is therefore great for common indoor plants such as Fiddle Leaf Figs, Philodendrons, Calatheas, Peace Lilies, Palms and more. Red light is great for flowering, while blue helps with vegetative growth. However if a plant gets too much of one colour, its possible they can grow a little deformed or out of shape.For green, leafy indoor plant growth or to keep your plant babies alive through winter or in darker homes , choose a full spectrum LED white grow light. These can be a little tricky to track down, so I personally recommend this Aspect pendant light from Soltech Solutions.

Plus, Soltech have kindly given a discount code for my readers! Seeing as grow lights need to be on for at least hours a day, you may want to invest in an automatic timer.

Using a timer will automatically turn the light on and off at whatever times you set for it. When we bring plants into our home, they become part of our decor and part of our lives! Grow lights provide us with the ability to do just that. Plants can often show symptoms of suffering in low light.

I also share a lot of plant tips over on Instagram — come join me! Thank you! I have noticed that most grow light bulbs only shine in one direction, with half the bulb obscured by a cover or something. The light they would receive would not be filtered through a lampshade, but it would be light reflected down by the lampshade, since the light emitted from the bulb would be directed upwards.

Is reflected light from a grow light bulb sufficient for growing plants? Hey Melinda, I would think that you would lose a lot of the power and effect of the grow light by doing it this way… Ideally the light will be shining directly on the plant from above. It might be worth getting a floor lamp where the bulb faces downwards?

One of the best and comprehensive articles on how to use Grow Lights for Indoor Plants, I am bookmarking it so I can read it again. Thank you, You really inspired me to learn more. This was really helpful, thanks! Would placing one or two grow lights in paper lanterns be a problem? The aim is for the grow lights to shine directly on the plants rather than through a shade. Hi there! Do you think one of those special light bulbs for reptiles would work for plants as well? Hope that helps!

Hey Lacey, they are quite safe however its always best not to look directly at the light for long periods! I used to sell it in my store which unfortunately had to close due to covid!

I just bought a grow light for my FLF. Do I need to gradually build up how much time the light is on? I know FLFs are finnicky and this is my first one. Your email address will not be published.

How long should a grow light be left on? To be effective, grow lights really need to be on for at least hours a day.

This can vary up to 16 hours, depending on the conditions. 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 choice. Young or shade loving plants can get away with less powerful grow lights, whereas large plants and ones with big leaves that can absorb lots of light eg Fiddle Leaf Figs can love the benefits of a stronger light. Think about how a plant gets sunlight in nature — from above!

Artificial Grow Lights vs The Sunlight for Plants

Different plants have different light requirements, and like other things, there is such a thing as too much light for some plants. Comparatively, in the full bright direct sun every day for hours on end, you have cacti. All the other indoor plants fall in between those on the light requirements spectrum. But, knowing if you can meet the indoor light requirements for your houseplants can be a bit challenging. So how do you tell what sort of light you have in different rooms of your home?

What Is a Grow Light? · The intensity of the lamp (known as the photosynthetic photon flux density or PPFD); · The wavelength (the spectrum of.

Lighting recommendations for successful plant propagation

The use of LED grow lights in crop farming has recently seen substantial growth. However, choosing the right light spectrum for plants and knowing how they affect photosynthesis, can be challenging and oftentimes confusing. This article aims to help you understand the light spectrums needed for plant growth and how full spectrum LED lighting is now widely used for crop production. Grow light spectrum refers to the electromagnetic wavelengths of light produced by a light source to promote plant growth. For photosynthesis, plants use light in the PAR photosynthetic active radiation region of wavelengths nmnm measured in nanometers nm. Nanometers are a universal unit of measurement but also used to measure spectrum of light — humans can only detect visible light spectrum wavelengths nm. Plants, on the other hand, detect wavelengths including our visible light and beyond, to include UV and Far Red spectrums.

How to use Grow Lights for Indoor Plants

Light is one of the most important factors for growing houseplants. All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates energy. Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die. Before getting a plant or starting seeds, determine the quality and hours of natural light in your space. Then choose plants with light requirements that match your indoor environment.

A grow light is an electric light to help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated.Outdoor conditions are mimicked with varying colour, temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation e.

Under the irradiation of infrared , the ripening of fruits tends to be uniform.

Lighting for Young Plants: Seedlings and Cuttings. One way to build a strong foundation, is to provide appropriate lighting during these critical stages. The goal of growing plugs is to have compact, uniform plants with a well-developed root system. Utilizing supplemental lighting during the propagation phase allows for more predictable and faster crop cycles, while improving overall quality and root structure. In addition, air temperature — and especially medium temperature — are important because temperature controls the rate of callus and root development. In this article we will explore the basics behind cutting and seedling production in relation to light.

Light requirements vary depending on the plant. For healthy indoor plants, light should respect the plant's native environment as much as possible. One of the biggest challenges in growing houseplants is getting the lighting just right. But light can vary in both intensity and quality.
