How Does a Grow Light Work?

A grow light mimics the light wavelengths that plants of all kinds use for their growth from seedlings to vegetation. 

Used indoors, a grow light provides an electromagnetic spectrum similar to that of the sun. 

Typically used for indoor gardening, a grow light is used extensively for such operations that include hydroponics and aquaponics.


Know About The Light Spectrum

All green plants require light to grow. Light is necessary for the process of photosynthesis, as this is how plants synthesize foods from carbon dioxide and water.

The light spectrum gets its definition by the temperature wavelength emitted by the colors, both visible and non-visible, that sunlight provides.

Most of the light that plants use is from the blue (cool) and red (warm) spectrum. Blue light will stimulate vegetative growth like the leaves and the roots on a plant. 

The red light in the spectrum will enable the plant to produce flowers and fruit. 

The amount of light that a plant needs to thrive will vary widely depending on the type of plant. 


Get The Needed Spectrum Light From Cheap Grow Lights

Grow lights provide the lighting needs for your plants. That is why it is necessary to know what type of light your plants need and what bulbs will deliver that light. 

You will find that early growth and maturity do better with warmer, short wavelengths of light. That would be towards the blue end of the spectrum. 

When it comes time for bloom and plant production, it is the time for the wavelengths found in the spectrum's red end.

Grow lights give you the ability to control what light your plants receive throughout all the growth stages. 


Growing Indoors

As an indoor grower, it is important to know a few basic concepts about lighting in general so that you understand how light affects your plants. 

When you know this, you will also be able to see what makes a particular type of grow light more suitable for your goals. In turn, this will save you time and money.

Light, both visible and invisible, falls in a range somewhere on a light spectrum. Spectrum measurements are nanometers. 

These nanometers correspond to the wavelength of light. As an indoor grower, you will need the 400 - 700-nanometer range.


Lighting terms

Light Intensity

The amount of light that reaches a surface (or plant) at any given distance from the light sources itself is called intensity. 

This is important to understand because a very bright bulb that is a foot away from a plant would provide the same light intensity as a dimmer bulb that is only two inches from the plant. 

So the intensity of a light bulb is important. The more intensity, the farther away from the plant, the light can be positioned.

The best cheap grow lights will deliver a light intensity that is enough for your plants to be able to grow from seeds to harvest. 

To do that will mean that you need 20 to 40 moles of light every day. You will want a grow light that will emit somewhere between 600 uMols and 925 uMols of light for a maximum yield. 

That will cover the 18 hour vegetation and 12-hour flowering that you need for your plants. 

If your grow lights have sufficient intensity, then the wattage is not a factor that you need to concern yourself with as wattage is not an accurate indicator of performance when it comes to grow lights. 


Most grow lights will have an on and off switch, but some have timers. In lighting terms, the duration is the number of hours that a plant receives light in a 24 hour period. 

You will need to know the duration of light required by the plants you are wanting to grow. 


The third lighting term that is important to know is color. This is simply the visual appearance of the grow light. 

Most, but not all, grow lights provide the full-spectrum light. As we had said previously, plants use blue and red ends of the spectrum. 

They use a little, but not as much, of yellow and green light. 


Consider The Stages of Plant Growth You Need Light For

If you are on a budget and trying to find cheap grow lights, you still need to provide the specific light that your growing plants will need. 

Consider the various stages of plant growth, especially if you are growing from seedlings.


LED Lights Are The Best For Growing Plants

The calibration on most LED lights meets the exact needs of an indoor plant. The blue lights will simulate stronger roots, enhance photosynthesis, and give peak growth. 

As a bonus, LED lights let off very little heat.

While LEDs may cost more upfront, there are still cheap LED grow lights that you can find. They are definitely the way to go. 

LED's use half the electricity and last five times longer than a fluorescent bulb, which would be your other choice for growing.

Not only is an LED good for your budget, but it is also good for the earth. 

LED tubes are mercury-free, and they don't shatter like glass. Fewer LED lights end up in landfills, which is a very good thing.


What to Look For When Buying a Cheap Grow Light

Good Spectrum

The best cheap grow light will have a balanced spectrum. Try not to choose a light that has too much blue or too much red. 

That will not give you enough to get through the veg or flower stage of growth.

In general, a good cheap grow light will use a white spectrum or use a balance of blue and red. 

Check it out by looking at the spectrum chart for the light you are considering. 

Size of The Cheap Grow Light

One of the first considerations when choosing a grow light is the number of plants that you will need cover for. 

Most cheap grow lights won’t cover much more than a 2 x 2-foot area. If you need more coverage than that, you will have to consider getting multiple units. 

Also, take into consideration if you will leave the plants in one location or if you might need to move them from place to place. 

If you need to move them, look for a cheap grow light that will be lightweight and portable. 

Type of Cheap Grow Light

There are various types of grow lights to consider. Some hang from overhead; there are panels or ones that will screw into a regular fixture. 

Take into consideration the type of plants you will be growing, if there will be any existing natural light, and where you want your plants located. 

That will help you determine what type of light would be best suited for your operation. 

Size of Your Space For Growing

The space you will have available for your growth will also influence the type of cheap grow light you will look for. 

The more that you grow, the more lights you will need. Even with cheap grow lights, that cost can add up quickly. 

Before you buy, know the footprint size that the light provides and what you need to cover.

In Conclusion

There are cheap, but quality, grow lights available to suit your needs. Before you buy, make sure that the light will do what you need it to do.

A bit of research before purchasing will help you choose the right cheap grow light and save you time and money.


Which cheap LED grow lights should I avoid?

Avoid the cheap grow lights that emit less than 400 uMol and cover a small space that is only about one foot. 

Don't get any that have an unbalanced spectrum, for example, only red or only blue. It isn't easy to find a good grow light for less than $100.

When I buy LEDs, should I buy them based on watts or lumens?

It is best to buy based on lumens; watts determine how much energy it takes to produce those lumens. The higher the lumens, the less energy you will need to produce the light.

What Is CRI?

CRI stands for Color Rendering Index. It is a measurement of the quality of light. CRI measures on a scale that runs from 0 to 100, with 100 being the best number. 

LED's are usually in the 70 to 95 range, with the higher the CRI, the more expensive the LED chip, and the more expensive the product itself.
