Many people desire to grow their cannabis to save money and enjoy the freedom of experiment. Light is one of the essential elements that a cannabis plant needs.
Plants turn light energy into chemical energy when going through the photosynthesis process. In turn, this allows them to grow strong and healthy. Light fuels bud production in cannabis. When you plan to grow cannabis indoors, grow lights can help you to have quick harvest cycles.
In this guide, we will look at some of the most popular LED grow lights for growing marijuana to help you in the decision-making process. We have tested these grow lights and found them to be reliable in marijuana cultivation. Let’s dive in!

Can I Leave My Grow Lights on the Whole Day?
No. It’s not advisable to leave grow lights round the clock, as this will force your plants to grow fast. As such, you need to keep your grow light on for around 12 to 18 hours. Keep in mind that too much light in different growth phases could interrupt the plant’s natural process of dormancy and growth.
The Main Difference Between LED Grow Lights and LED Lights
LED lights can only provide illumination to plants. LED grow lights, on the other hand, provide a wider spectrum of blue and red light that a plant requires during the growth and flowering stage.
We recommend that farmers use suitable LED grow lights. This is because they provide cannabis plants with the right colors. This is important since they need the lights for growing into healthy plants.
Blue light is necessary for plant growth. The green coloring matter in leaves absorbs blue light in the atmosphere. The plant later converts it into energy through photosynthesis.
Effects of Blue lights on Cannabis Plants
Blue light gives plants robust lateral growth. Plants with a spectrum rich in blue light tend to have darker leaves. This is ideal for the flowering period. Low exposure to blue light levels causes cannabis plants to develop a shade-avoidance. This syndrome causes the plants to stretch and seek blue light away from the shade.
When plants have a high green: blue light ratio, they will think they have shade over them. This makes it important to include blue light as one of the colors in the broad-spectrum light. Additionally, plants that lack enough blue light will grow longer shoots. This is a way of getting exposure to blue light. If there is no sign of blue light, the cannabis leaves start to exhibit leaf hyponasty. This is not a good sign, especially if you grow your cannabis indoors.
When cannabis isn’t getting enough blue light, it’ll compete for light exposure. It achieves this by growing longer shoots. Lack of enough blue light causes the plant to develop an inefficient root system. This root system cannot support the entire plant’s nutrition. Also, blue light regulates the opening and closing of stomatal pores.
Gas exchange is critical since it brings in carbon dioxide gas. CO2 is necessary for the photosynthesis process. Therefore, you need to include some blue light when you provide cannabis plants with light. The bottom line is: Blue light cannot be as effective as when you combine it with red light.
To summarize, LED grow lights allow your cannabis plants to be high-yielding and healthy when grown indoors. You don’t have to worry about how you will provide your plants with the right spectrum exposure.
