Why are LED Lights the Best Choice for Marijuana Growers?

There are a number of different options for growers when it comes to lighting up their grow tents or grow rooms. These include high-intensity lighting options such as HPS grow lights or Metal Halides. Then there are also CFL lights and other old-school types of lighting choices. However, most growers these days are preferring LED grow lights over these lighting solutions. This is because of a number of reasons – but the biggest benefit that growers get from using LED grow lights is that they are much more power-efficient. There’s a huge difference in the power consumption between LED lights and any of the other older forms of lighting.

While power consumption is the biggest reason as to why more and more growers are now using LED lights, there are some other reasons too. Heating is one such reason. LED lights generate much lesser heat when you compare them with older forms of lighting. LED lights are also non-toxic in nature as they do not carry any chemicals in them and can be disposed with a much greater ease. Lifespan is another major factor as LED lights can last you as many as 100,000 hours – which means 11 years of continuous use! Lastly, LED lights are easier to repair too – and even if some LEDs stop working it doesn’t affect much as there are many others on the panel which won’t be affected by one of them going bad! These are just some of the reasons as to why LED lights are being preferred over other forms of lighting these days. Let us now cut straight to the main story and look at what are some of the best options that you have –

Buyer’s Guide to LED Grow Lights: What to Consider Before Buying the Lights

Now that you know which are the 10 best LED grow lights that you can buy for growing marijuana indoors, let us now take a look at some of the factors that need to be kept in mind before you purchase these lights:

  • Coverage: You must know what is the exact coverage that your LED grow light is providing you with and will it be enough to cover your plants? Coverage matters a lot because based on that you might have to buy multiple grow lights to ensure that all your plants are properly getting it. There’s no point buying a grow light which offers a coverage smaller than your existing setup.
  • Power Consumption: You must know what is the exact power draw that your grow light offers. A 600W LED grow light does not consume 600 Watts of electricity from the wall socket – the number is much, much lower – always check the exact power draw before you buy your light.
  • Durability – Durability is another factor that growers must keep in mind before they buy their LED grow light. In case of any damage, bump or fall, your light must be sturdy enough to survive. Durability also includes the lifetime of the product. A 600W LED grow light should last you a minimum of 50,000 hours going all the way up to 100,000 hours and beyond.
  • Lighting Spectrum: Make sure that the lighting spectrum on your LED grow light is a full-spectrum setup. This will ensure that the light coming out of the LEDs will jointly give an effect of being very similar to the natural light of the sun. Plants need lights of different wavelengths at different phases of their growth and you must make sure your grow light offers the complete spectrum of lighting.
  • Cooling and Safety Measures: Another thing you must check is the cooling capabilities of your grow light. While LED grow lights don’t tend to heat up as much as some other types of grow lights in the past – they still generate some amount of heat and there must be a proper heat dissipation system in the light which will ensure that the heat does not accumulate and damage the product! Safety standards also need to be properly followed by the manufacturer. 
  • Price and Warranty: Price and warranty are the last two things that you must check but they too are very important. The price of LED grow lights is usually quite cheap but some brands such as PlatinumLED can be quite expensive. Also always check the warranty of the light that you are getting – it must be

Frequently Asked Questions about LED Grow Lights

Here are the answers to some of the most common questions that are often asked by growers about 600W LED grow lights. We strongly recommend that you go through these questions as well as they will help you gain a much better understanding about the lights:

1. What is the use of an LED light?

When you are growing marijuana indoors, you need to artificially recreate many factors of growth which are otherwise present naturally outdoors. One such factor is sunlight – which is very important for the growth of plants. Using a full-spectrum LED grow light ensures that the plants are getting proper lighting. Lighting is very important because light helps the plants produce chlorophyll and photosynthesize properly, as well as helps it in various other processes of growth. A full-spectrum LED light ensures that the red as well as blue spectrum of light is provided to the plants which helps them grow through their vegetative phase as well as the blooming/flowering phase. This is the reason LED lights are important.

2. How many plants can I grow under a 600W LED grow light?

It depends upon the coverage that the light offers you. You need to first know how much area your plants are occupying. Then, make sure you check out the coverage in the review to know exactly how much area the light covers and independently you can choose the number of lights to see what fits your setup the best. 

3. Who is a 600W LED grow light meant for?

A 600W grow light isn’t as high intensity compared to 2000W or 3000W lights. However, the light output is enough for a small setup operating for a personal scale of growth. If you are growing very few plants then this is a good option for you. This light is also good for growers who want to buy cheap LED grow lights as a backup option in case their main lights go bad and need repairs. These are also a good ‘extension’ lighting option. 

4. Is it legal to use these LED grow lights?

Yes, using LED grow lights is legal. There are no laws which stop growers from using LED grow lights – as these lights can be used for growing a number of different indoor plants which might be vegetables or ornamental plants. However, there might be some legal troubles if you are using these grow lights to grow marijuana as growing weed might not be allowed in all jurisdictions. Laws against weed are getting liberal over the past few decades but still it is illegal to possess or grow weed in many places around the world. Make sure you are aware of your local laws before you start growing your weed indoors.

5. Which is the best LED grow light?

You can go through our checklist above to decide it for yourself! The best lights, in general, are the ones which are bright and offer you a full-spectrum and have a coverage space enough to cover all your plants. They should also consume less electricity and offer a good warranty and after-sales service. Do refer to our buyer’s guide just above the FAQs section to get a much better picture of the light of your choice.
