I am quite sure you need to know what I am going to write in these sections discussed below.

What is an LED grow light?

Let’s start with a little intro about the thing I need to discuss in detail that is the “LED Grow light”

If we separate the three components of this little bunch of words I just wrote, we get:

LED – that stands for light emitting diode

Grow: it helps plants to grow best when they have been planted indoors

Light:  it provides light energy that will mimic the way the sunlight would have affected these plants when grown naturally.

It provides various wavelengths of light including UV and IR rays that can directly increase the growth and hence the yield of any plant grown under these lights.

You know what, after I have told this, the words coming out from pros in this field would be, why we have to read it further we already know this,, but I should say no to this. Because, every grower has his or her own experiences and if he/she has found success then you should know the what are the secrets behind the success.

And that’s what I am going to do here, sharing tips, tricks and secrets about what I have learned, earned and grown, using my 10 years of indoor plant growing adventure.

The indoor plantation success secrets revealed!

The role of LED grow lights in my grow rooms is pivotal and I must say that without these tiny wonder lights I might have not succeeded so much as I have done now.

I’ll keep my discussion to the point and focused on these wonder bulbs for plant growth. Let’s start with the best ones that I have sorted out after years of experimentation and experience.

Apollo horticulture GL45LED has the third place in my top 3 LED grow light list. It offers a well balanced 4 bands light spectrum for vegetative and flowering phases. It has the capability to cover 4-5 square feet of the plant area, depending upon the phase of the growth. Now, why I have included it in my list? It’s because it can operate in a wide variety of set up like, grow room, greenhouses, hydroponics, etc. It’s totally maintenance free and will not require any heat removal set up or fans and can easily be placed near the plants.

How Do LED Grow Lights Work?

Now, if you still have questions about how these tiny little lights can help your plants grow better when there is no sunlight, then I am here to answer these queries as well. The answer is simple …

Here is what happens:

When the plants are placed under the LED grow lights the lights emit a certain amount of photons to the surrounding area. These photons are emitted in the form of rays towards the plants having various wavelengths.  Plants absorb these rays and these rays activates the cell division among the plants. Plants have a tendency to absorb more blue light than other colors like white, or green. And hence the UV  rays are best to induce rigorous plant growth. While the infrared rays are best catalysts for germination and blooming boost.

The wavelengths can be adjusted according to the requirements of your plants in the grow room.

If you have plants to grow  that are in their vegetative phase, then using UV rays would increase the cell division when the plants absorb the rays. Due to the increase in cell division the plants grow quickly and result in more yield.

In case you need to treat your plant on flowering stage the best, effective LED light are those which provide IR rays. Infrared rays are best to enhance the bloom stage of the plants. These rays are readily absorbed by the buds and apex of the plant and cause them to bloom quickly and heavily.

I’d recommend to have  LED grow light that has a wide range of wavelength options available, so that you can adjust according to the effects you need.

The amount of light, type of light emitted, types of plants being grown, Lumen per area, wavelength and the height between plants and the light can affect the growth of the plant being treated.

Benefits Of Using LED Grow Lights?

According to my knowledge, before the rise of these LED grow lights there were other similar methods in use and were practiced commonly. These include HPS methods and fluorescent bulbs. But these methods were not at all favorable for small grow room owners who need to have a small, compact structure to assist them in their indoor plantation venture. You know why? Its because these previous methods needed a  lot of space to set up the whole equipped due to the huge amount of heat being produced and the need to have a proper ventilation system to avoid heat build up.  And all this mess made that process out of reach for the small grow room owners.

Now if you can see what we have got by having these LED grow light with us, it can clearly be noticed that these lights have made each and every grower either a hobbyist or a professional able enough to grow indoor plants using LED lights at their ease. If you need to know what benefits can you get using them here are my experiences:

1. Compact and easy to install

These lights come in a very compact structure that is very easy to handle. You will not need any specific infrastructure to get it installed and you can just have a proper place to hang them above the plants at the required distance.

2. No need for separate ventilation set up

These lights don’t emit a lot of heat and there is no need to have a proper ventilation system and they can work without any huge ventilation setup and type of large fans.

3. Can be installed adjacent to each other

As said earlier they have a compact design and most of them can be installed adjacent to each other in order to give more coverage.

4. Variety and control

Their wavelengths can be adjusted easily and also the modes for vegetative and blooming phase can be chosen.

All these factors have made me a great fan of these LED grow lights. Because you have a complete control over what you need to get through them.

Some important things that should be considered while choosing an LED Grow light

Choosing a perfect LED grow light for your grow area would need to have some important things in your mind:

Following are some of the most important things you should keep in mind when choosing an LED grow light:

1. The area you need to cover

The first thing that you should keep in mind is the area that needs to be covered. By knowing this you can decide how many LED lights would you need and which type of led’s will provide you the best coverage. Just keep in mind that 5000 lumens  are equivalent to about 50-80 watts. And if you have an LED grow light having a power of about 250watts then it should be covering about 5-6 sqft area.

In order to cover more space, more lights can be placed adjacent to each other.

2. The phases of the plant growth you need to treat

Also, you have to know the growth phase of the plant you need to treat or enhance. If you need a full growth cycle using these lights, then you should select a full spectrum LED grow light to assist in all phases with different wavelengths within your reach.  And also prefer to have UV and IR in the selected grow light.

3. Variety of light wavelengths you want to have

Keep in mind which wavelengths you would need to use in your grow area and focus to have them in your selected LED set up.

4. Type of plants

Different plants have various needs and you should select a grow light that caters to the needs of your plant.

5. Angle of the LED lens

Also look for the angle of dispersion within the LED bulbs. The greater angle means more coverage while the lesser the angle value the lower will be the dispersion.

But lower value means better targeting and higher angle value means more dispersion and less targeted supply of the light towards the plant.

How many watts do I need?

In order to know the exact wattage you should have in your grow area. You should  first calculate the area and the number of plants you will need to cover.

If we consider that 1 sq.ft has 1 plant potted in it, then, the recommended wattage is 25 watts per plant per square foot. If you have two plants in one sq.ft then the recommended wattage per square ft would be 50 watts and so on. So, if we consider our example discussed earlier, we have an LED grow light having a total wattage of 250 watts it would be best for 8-10 plants growing under it.
