Buyer’s Guide for Led Grow Lights for Cannabis

Now that you’ve been through our list of the best lights for growing weed, you must be ready to make your purchase. Here are some details you should know about grow lights to help you out.


What to Look for in the Best Lights for Weed?

There are some features every good grow light should have. Here’s how to assess some essential aspects to check if the light will work for you.


  • Light Proportion

First of all, take a look at the light proportion. That’s whether the grow light is full-spectrum or not. This depends on the plants you intend to grow, but for weed, the best option is to go for a full-spectrum combination that mimics sunlight.

However, if you want fast growth and higher yield, you can go for LED lights with more UV and IR proportion.


  • Energy Efficiency

Energy bills will take up most of your grow room costs. But, you can avoid spending too much by investing in an energy-efficient grow light. Look for a light that gives out a high lumen output while using minimum energy.


  • Heat Management

Most of the cheap grow lights available online run bright and hot, damaging your plants in the process. That’s why you should look for lights with a productive heat management system.

Aluminum panels with vent holes do a great job of cooling the lights down while they run. Some lights also have one or more than one cooling fans to regulate the temperature in your grow room. Make sure the fans operate noiselessly; otherwise, you’ll have to find a secluded place in the house for your grow room.


Tips for Operating Weed Grow Lights

If this is your first time setting up a grow tent, you’ll need to learn the basics about grow lights to know how they work.

  • Don’t keep your grow lights running all day. Your plants need rest. Give them at least six to eight hours of nighttime each day.
  • Keep changing the placement of your lights with different growth stages. In the beginning, fix the lights about four inches away from the plants and take them further as the plants grow.
  • Water your plants according to the lights you use. Plants under LED lights don’t need much water as there is minimum evaporation. In this case, excess watering might damage the plants.


Wrapping up with the Best Light for Growing Weed

In a nutshell, the best LED grow light for weed is the one that fits your needs in every way. In our list, we’ve mentioned LED lights, fluorescent bulbs, and blurple lights, each of which has different purposes and effects on your plants.

Before you make your purchase, check the needs of your plants, the size of your grow room, your target yield, and your budget. Remember, the most expensive lights don’t need to be the best ones for your plants.

You should also check features like light proportion, safety features, light intensity, and maintenance costs. These aspects will help you find out whether the light will work for your grow room or not. At all costs, avoid cheap lights with scorching effects on your cannabis. Happy Growing!
