Getting started growing cannabis with LED lights

While Greenlight Distribution serves commercial cannabis cultivators, we get a lot of questions from new growers about how to start cultivating cannabis. Specifically, we talk to many people about LED lights.

Cannabis is a popular plant to grow for both medicinal and recreational purposes. It is also a versatile plant that can be grown indoors or outdoors, but when it comes to indoor cultivation, the choice of grow lights is critical. LED grow lights are becoming increasingly popular among cannabis growers due to their energy efficiency, low heat output, and customizable spectrum of light. 

In addition, they LED lights can qualify for significant cash back in the form of federal, state, and local energy rebates.

In this article, we will provide a beginner’s guide on how to grow cannabis with LED grow lights.

Choose the right LED grow light for cannabis.
Cannabis requires a specific spectrum of light to grow properly, and not all LED grow lights are created equal. When choosing an LED grow light for cannabis, look for one that has a high ratio of red and blue light, as these are the wavelengths that cannabis plants need to thrive. Also, consider the size of your grow area and the number of plants you want to grow, as this will determine the wattage and coverage area of the light you need.

Set up your LED grow light.
Once you have chosen the right LED grow light, you will need to set it up. This typically involves hanging the light above your plants and connecting it to a power source. Be sure to follow the manufacturer’s instructions for proper installation and use.

Adjust the distance between the light and plants.
It is important to adjust the distance between the light and plants. The plants should be close enough to the light to receive the right amount of light, but not so close that they are burned or damaged. A good rule of thumb is to keep the light about 12-24 inches above the plants during the vegetative stage, and around 18-24 inches during the flowering stage.

Monitor the temperature and humidity.
LED grow lights can produce heat, so it’s important to monitor the temperature and humidity in your grow area. If the temperature gets too high, it can damage your plants, and if the humidity is too low, it can cause your plants to dry out. Optimal temperature and humidity levels for cannabis plants are around 70-85°F and 40-60% respectively.
Shop for dehumidifiers.

Schedule on and off time for the lights.
Cannabis plants have different light requirements during different stages of growth. During the vegetative stage, they need 18-24 hours of light per day, while during the flowering stage, they need 12 hours of light and 12 hours of darkness. Be sure to schedule the on and off time for your LED grow lights accordingly.
