Things to consider before buying an LED grow light

There are various kinds of LED grow lights available in the market ranging from a $100 to $2000.

So, how would you decide which one is the best LED grow light for you?

Well you need to ask yourself a few questions for that. Below is list of things you may want to consider before buying the LED grow lights.

  • How much area do you need to cover? (covering larger area means more expensive LED)
  • What is the power consumption of the product? The more power it draws a minute the more money you spent keeping it running. In the market you can get LED’s of different wattage like 200W, 600W, 1200W and so on. (on average the more power it draws, the more expensive the LED would be)
  • Does the LED use top end Diode bins? (top quality diodes means higher price)
  • What is the PAR efficiency? (PAR – Photosynthetically active radiation) it is a region of the electromagnetic spectrum (400 to 700 nm) that promotes photosynthesis.
  • Do you need secondary lenses for you grow space? Adding secondary lenses would increase the light intensity as well as the price of the LED.
  • What kind of light angle do you want? A large angle would indicate that the light is dispersed on large area and a small angle would show that the light is being dispersed less and is more direct.
  • What kind of feature do you want? These include things like dimmability, spectrum control, timing, schedule controlling etc. Adding these features generally means more money.
  • Warranty. The longer the warranty of the product, the higher it price.
  • Finally, what is your budget?

How to Choose the Right LED Grow Light

The type of LED grow light you choose depends on few factors like how much are you willing to spend on a grow light and what features you want.

Obviously, the cheapest LED grow light will not be the same as the high-end LED. Now, those who have never used an LED grow light (or have used CFL) to grow marijuana indoors may ask “why you would want to use it?

Well obviously the first reason would be to keep the plant out of prying eyes but other than that, there are some benefits of using LED grow lights: they can produce more yields in your weed plants while remaining cool and they also use reasonable amounts of electricity.

Because of the various spectrum of lights (as compared to the LED’s which were used a decade ago) they make the buds healthier, greener and more attractive. The following list shows you the benefits of using LED grow lights to grow marijuana indoors.

The Checklist:

Some of you may be just heading out on the journey of growing weed indoors.

So, we are happy to show you the ultimate grow room equipment checklist.

This is by no means an exhaustive list but it gives a general overview of what equipment people are actually using in real world.

  • Exhaust fans – One of the most important factors in growing weed indoors is the air temperature and quality. Having exhaust fans will ensure that the air is circulated properly, but pushing the old air out and sucking fresh air inside the room. While preventing the room temperature to rise.
  • Lighting – You don’t to worry about these as we will provide you with the reviews of the best led grow lights of 2018 (although you need to decide on all the factors we talked about earlier).
  • Air conditioning/Temperature control – This depends on whether you live in a hot place or a cold one. If the temperature is too high, it will kill the plant. And if it’s too low then it can cause disease in the plant. Now we cannot say what exactly you would need as it all depends on where you live, what time of the year is it, the temperature of the air which is being sucked in, the insulation of your room etc. you would need to calculate all of these and decide on the equipment you want.
  • Hardware – This is basically the structure you would need to keep your plants, this depends on you whether you want it to look very good and have proper shelves or a basic setup to fulfill the needs of plants.
  • Mylar/Tinfoil – If you want cheap reflection then you can use tinfoil which would rip easily or you could use Mylar if you have high budget, which in turn would light up your room like a spaceship. There are other costly options as well but for a beginner these would be appropriate.
  • Grow tent – This is an optional item, you can use one or you can use the whole room as growing space, But if you want to grow weed indoor then we recommend you to use it!
  • Nutrients – You would want to provide the plants with some good nutrients to make it healthier and better yielding.
  • Sensors/control system – You have to control temperature, CO2 amount, humidity, lights among other small things. If you forget to turn on/off something and goof up then you risk spoiling the plants. So, the best way to avoid general problems is to have a control system that would do the things for you. It will make your life easier. It may be costly but it will give you peace of mind.
  • Sunglasses – It’s important to take care of your eyes and avoid UV rays, so you must wear good anti-UV sunglasses when working inside your growing room.
  • Growing system – Figure out what kind of growing system and soil are you going to use.

Be careful about the hanging distance:

Different lights have different hanging distance. By hanging distance we mean the distance between the LED grow light and the top most part of the plant. As the plants grow, they tend to reach the light. Therefore, move your light up as the plant grows keeping the distance uniform.

If you want the plants to grow tall then continue raising the LED, if you want shorter plants then do not raise the LED. This way the plant will be short and bushy.

Don’t move the LED light during the flowering phase. If the LED is too close then you risk killing the plant, so always follow the recommended distance.


So we have talked about a lot of different LEDs grow light in the market now it’s up to you to find the best LED grow light for yourself.

Ranging from cheap $20 ones to very high-end costly LEDs. All the LED’s shown were handpicked for you as to help you choose. So how would you decide which the best is for you?
