Why you need a grow light for your indoor plant
Plants need light to grow
Growing indoor houseplants is a pleasure.
Watching them develop into the plants you wanted.
Seeing them mature into something to be proud of.
But what happens when the sun goes in or is not there for long during winter ?
The plants food factory slows down to a crawl.
It doesn’t look it’s best.
You feel like you should be doing more.
Well…what if you could – what if you could add a bit of light to your plants life.
All plants need light to grow and nowadays with the advent of double glazing to help keep us warm, snug and safe.
The amount of useful light for plants is reducing.
Where is the best lighting for a plant… outside.
Not always practical when they need to be kept at above ambient temperatures.
Or even outside if they are used to longer days throughout the year… they need more light…
Or if it not practical to place them all on the windowsills – do you have an alcove begging for a plant to be placed in – but you know if you do you will be moving it again in a week when it fades.
Why not show them off to their best, help them do what they do naturally and give them more light.
even if you plants grow too big for your aerogarden lights – you can remove them and add supplementa lighting.
What choices have you got
On the market place you have three main technologies for home use.
These are now the ‘old fashioned ‘ bulbs that were the only type you could get a few years ago.
With their heated filament, getting the glass so hot in minutes that touching it left fingerprints on it.
The color of the light was more often a warm white – or yellowy white.
And were slightly fragile when hot – trying to move the bulbs resulted in filament breakage and bulb replacement.
Fluorescent or CFL bulbs
These used to be only in shops, long tubes high up to illuminate with their ghostly light.
But they developed into a usable replacement for the filament bulb.
More efficient, lower power and more light output than traditional filament bulbs.
There were a few downsides.
They a very small amount of mercury within them, along with multi coatings of phosphor.
These phosphor coatings produce bands of light – we see it as white, but it really is multiple narrow bands – that’s what you plants see.
They are as fragile as the filament bulbs in a way with their glass tubes, now woven into intricate patterns to fit the same space as their former bulbs.
Led or Light Emitting Diode
These modern technology marvels have reduced the power and are able to cover the same spectrum as the filament bulbs and more.
The tiny bits of silicon with different added chemicals produce different light colors.
Or back to the phosphor, they can produce a warm white or a cool white.
They last thousands of hours, if treated right – keep them cool.
Highly directional, the light output can be easily focused on one area or spread over a wider area with built in optics.
Personally out of the three technologies I would always now pick led lighting for the convenience of low power, high brightness and long life.
Adding more light for your plant in the right place now doesn’t mean cooking it with a filament bulb, or illuminating your plant with multi spectrum light from a fluorescent but being able to have lighting close to the plant where it does some good with leds.
To get the light where you want it, you have some choices of fixture.
Where a clip, or clamp can be used to fix the light base to a shelf or the edge of a saucer.
Most of these lights come with gooseneck lights to allow positioning them at whatever angle you want.
They come with either bar or bulb lights .
The bar light allows a broader spread of light but at a lower intensity.
Whereas the bulb is more intense and suitable for the more compact plant.
The panel light
These lighting panel are suspended above the plants – similar to the sunlight they simulate.
If you can make the height adjustable then you can keep the intensity of the light almost constant allowing the plants to grow naturally.
If the light is positioned too far above, then seedlings will start to grow leggy and have weak stem, not able to support the mature plant.
Floor standing lights
If you have tall architectural plants that could do with a boost over the short day period then there are floor standing models available.
These have a short tripod and a boom fitted with the lighting element at the top so they can be tucked out of the way and can remain discreet behind the plant.
They are adjustable in height to cover a wide range of heights.
They come with either panel elements, bar elements or bulb elements.
They tend to feature a gooseneck for positioning the lighting element.
When placing the plant in an alcove you can create accent lighting with wall mounted lighting, with a remote control you can adjust the color of the lights to show the plant off in its best light.
But remember to go back to the broad white light for most of the day to assist the plant in growing healthily.
This sort of lighting would need to be fitted by a qualified electrician, so if you have a need of this sort of lighting then definitely call out an electrician to at leas fit an electrical outlet in the alcove where you can then add led strips or panels.
What color does your plant like
Sunlight cover the whole of the human visible spectrum and a whole lot more.
Well into the ultra violet ( tanning rays) and up to the infrared (some plants reflect this for insects to find them).
What we tend to do with plants is to assume that they only need visible light.
And there has been a vast movement to show that blue light is needed for growth and red for flowering.
Well the plant needs the whole spectrum of visible lighting and more.
But it is really beneficial to have loads of light.
There are loads of blue red lights on the market – and if this is something you like ( with both of these on the plants look black…) then go for it.
But personally, if the plant is in the living space no one want the intrusiveness of this type of light.
Ok… to have the white leds is to have less efficiency, but they output a pleasing light and cover the whole spectrum, rather than just very narrow bands.
But the plants will thank you for it with the infill light in the yellow and green areas.
And in the winter the extra lighting may help you with the symptoms of SAD ( seasonal Affectorial Disorder)
To get the most benefit if you are after leaf growth then go for a cool white – the leds allow more of the blue light through.
And if you are after flowering then the warm white is better, as there is slightly more of the red spectrum.
If you want to get technical then these are some spectra of different lights – showing the difference between a filament bulb (covering the whole of the visible spectrum and more), a cool white led ( again covering the visible spectrum) and a flourescent ( with bands of light – not ideal for plants)

So which one are you going to choose to help your plants over the low light period?
Let me know in the comments below which led growlight for your indoor plant you are going to choose and what sort of plants you have.
Indoor Led Grow Light FAQ
Are led lights any good ?
led grow lights are more efficient than any other lighting at the moment.
And with either the right narrow colors or the whole spectrum lighting they are excellent for supplementing or being the only lighting for plants.
Can you use a grow light bulb in a regular lamp?
You have to remember that there is still some heat created, and in a standard lamp the cover will not allow this heat to escape.
And one thing that will reduce the life of leds drastically is heat.
And heating the controller electronics up above 120F (50C ) will cause premature failure
So it is better to go for a designed low voltage lamp rather than a high voltage one.
Can you use any led lights to grow plants?
As long as they are the right color and the right power – yes.
So you can use the strips of leds as long as there is enough of them and they are the warm white type.
These can line an alcove to illuminate the plants residing within to allow it to grow healthily
Do grow lightw work for houseplants?
They most definitely they do.
Almost any indoor plant over the winter or very cloudy days can do with some supplemental light.
With double glazing on the rise , less light is allowed into out homes – so any indoor plant will be slightly starved of natural sunlight
It is not always possible to place your plants in the optimum position.
Do you need a grow light to start seeds indoors?
To start seeds off you need heat light and moisture.
Growing sedlings indoors requires a lot of light at the right time .
So trying to get a head start on the season means adding supplementary lighting for a few hours a day.
This will prevent leggy spindy seedlings from growing and produce healthy seedlings which will grow into very healthy plants.
How do you make grow lights?
Get a timer to control how long the light is on and off.
Get some full spectrum leds
And a power supply suitable for leds.
And connect them up.
Make sure you follow good practices for extending the lifetime of the leds and don’t overload the controller.
Alternatively as they are reltively cheap why not invest in a properly made one.
How long should plants be under a grow light?
Plants, like us, need a resting period.
They reset themselves for the next day when in darkness.
So allow them at least a 6 hour resting period with no light or even 8 hours.
This allows them to grow healthily.
How much does it cost to run a 1000w led grow light?
If your 1000w light actually takes 1000w then in 1 hour you will use a unit of electricity.
But most led lights are promoted with hte maximum power the leds are rated at.
And are run at half or less of this power – always worth reading the specs.
So 1 unit is 1kwh or one kilowatthour – so if you use up 1 kilo( 1000) watts in one hour then you have used a unit of electricity.
What is a full spectrum grow light?
A full spectrum grow light is not one made up of different color leds
It covers the visible spectrum of sunlight as a minimum and works with phosphurs.
This is the reason you can get warm ( more red) and cool( more blue) leds.
To balance the light output you are better off looking at the warm white leds.
What kind of led lights grow plants
You can use the two colors of led red and blue, but if it is in the living space this may not be the most attractive of beneficial for the eyes.
Adding other colors will make it more like the white light of a flourescent tube and ‘fill in’ some of the colors.
And yes these do work.
But for having in the living space a warm white light would be the best compromise.
