Growing plants and flowers is tricky enough outdoors. Maintaining the right amount of water and nutrients while protecting a garden from the elements is a balancing act. Many people turn to indoor gardens to avoid the challenging growing conditions of the winter or harsh environments. This route, however, brings its own set of challenges.

First and foremost, you are going to need some light. Grow lights provide the same energy to indoor plants that the sun brings to the outdoors. Without them, photosynthesis would be impossible and the plants would die. So choosing best led grow lights for indoor plants is important.

 

Benefits of Choosing LED Grow Lights

Of all the lights available today, LEDs are the most energy efficient for growing cannabis. In a day-by-day comparison of operating costs versus power output, they easily beat out fluorescents – and even the HID lights that have dominated the indoor growing scene for decades.

A big advantage of this efficiency is their cooler operating temperatures. With very little heat put off during their lighting cycles, using LED grow lights can often let you do away with ventilation systems altogether. Even if you’d prefer to keep a vent fan for humidity’s sake, you’re still able to position LEDs closer to your plants without fear of light burn.

While LED grow lights will often be a more costly initial investment, their return on yields is only the beginning of where they pay off. Overall, we consistently choose LED grow lights for our cannabis cultivation because they just make things simpler.

Plug them straight into an outlet (unlike the ballast needed for HIDs), and their low-heat operation will keep you watering and adding nutrients less… And trimming and harvesting more.

How do LED Grow Lights Help You Succeed In Growing Marijuana Indoors?

LED lights are useful in helping you succeed in growing marijuana indoors because of the fact that they are basically acting as a replacement to the sun! While this sounds like a rather difficult thing in theory, but in practice, when you consider this, it is actually quite simple. The sun acts as a source of two basic things that your weed plants need to grow: light and heat.

LED lights help make growing marijuana indoors quite easy for you by providing light and heat to your plants. The more concentrated the light is, the higher the heat is – basically, the closer the lights are to your plants, the hotter the heat levels are. Hence, depending on the stage of growth your plants are, you can actually adjust your lights to provide appropriate light and heat for them. For those wondering what the plants do with the light and heat – they generate energy and pigments which help them with their growth.

Furthermore, there’s another great benefit of these LED lights – they do not produce so much heat that can be adverse to the growth of your plant. Unlike traditional lights, which can often end up burning your plants, that risk is much lower when it comes to LED grow lights. In addition to that, using them is more economical as well because they do not consume as much electricity and can provide the same output as those of traditional lights with a higher wattage! LED lights are also simple to set up and non-toxic in nature as they do not contain chemicals which can harm you or your plants in case there’s a breakage.

Final thoughts

Grow lights are very important for the well being of your marijuana, or any plant for that matter. They replicate the light of the sun and thereby help the plants in growing towards their direction and also help in generation of energy via photosynthesis. By varying the levels of light and heat that you provide the plant you can also play with the chemical composition of the plants and ensure the weed is as strong as you need it to be. If you want to grow indoor, you need to choose grow lights for weeds. ECO Farm LED grow light can be your great choice.
