How LED Retrofit Can Improve the Growth of Indoor Cannabis

Growers are always looking to optimize yields and quality while reducing costs in cannabis cultivation. Upgrading outdated lighting is one of the most effective ways to achieve their goals. Retrofitting existing lighting with new LED fixtures is a middle ground between keeping old lights and a full lighting replacement. LED retrofitting is just the conversion of existing HPS fixtures to LED lighting fixtures while using the existing electrical setup. This makes upgrading simple and affordable.

Benefits of LED retrofit for indoor cannabis

Transitioning from traditional HPS lights to LEDs provides a wide range of benefits for indoor cannabis cultivation. While retrofitting to LED requires some upfront investment, growers who make the switch see improvements in yields, quality, and profitability. Here are some of the top advantages of LED retrofits:

Improve the quality and yield of cannabis

According to a study by the University of Guelph, LED lights can increase the cannabinoid content, terpene profile, flavor, aroma, and appearance of cannabis buds. The study found that LED lights produced higher levels of THC, CBD, and other cannabinoids than HPS lights, as well as more diverse and potent terpenes. The study also reported that LED lights enhanced the color, density, and size of cannabis flowers.

Another study by the Wageningen University and Research Centre found that LED lights can increase the yield and biomass of medical cannabis. The study compared the effects of LED lights and HPS lights on two cannabis varieties: bedrocan and bediol. The study found that LED lights increased the dry weight way by 20% for bedrocan and 24% for bediol.

These studies show that LED grow lights can improve the growth of indoor cannabis by enhancing the quality and yield of your cannabis crops. By switching to LED lights, you can produce more potent and desirable cannabis products that can increase your profits.

Energy efficiency and cost savings

LED retrofitting offers substantial energy savings compared to HPS lights commonly used in indoor cannabis cultivation. LEDs are renowned for their energy efficiency, converting a higher percentage of electricity into usable light while generating minimal heat. LED lighting can consume up to 75% less power compared to conventional lighting. This efficiency translates into reduced electricity bills, allowing growers to save on operational costs in the long run. 

Enhance spectrum control

A major benefit of LED retrofitting is the ability to tailor the light spectrum according to the specific needs of cannabis plants at different growth stages. LED lights can be fine-tuned to deliver precise wavelengths, replicating the natural sunlight spectrum. This allows growers to optimize the lighting conditions for each phase of plant development, from vegetative growth to flowering. By tailoring the spectrum, growers can influence crucial factors such as boosting cannabinoid and terpene levels, resulting in higher quality and more potent cannabis. 

Lower heat output

Indoor cannabis cultivation requires careful temperature control to maintain an ideal environment for plant health and productivity. Traditional lighting systems generate significant heat, necessitating additional cooling measures. LED retrofitting, on the other hand, produces considerably less heat, minimizing the risk of heat stress and allowing growers to maintain consistent temperature levels without excessive cooling requirements. The lower heat output of LED lights not only contributes to healthier plants but also reduces consumption associated with cooling systems. Moreover, the lower heat emission of LEDs reduces the strain on HVAC systems, leading to additional energy savings and maintaining the optimal temperature conditions for robust plant growth.

What to look for in LED retrofitting

Spectrum customization

Having the ability to customize the light spectrum is critical for indoor cannabis cultivation. Look for LED grow lights that offer precise spectrum control, which allows tailoring the light wavelengths to the specific needs of your plants at different growth stages. Variable spectrum LED grow lights are the ideal option for your indoor cannabis throughout the whole life cycle. Adjusting the spectrum enables influencing key factors such as cannabinoid and terpene production, enabling you to produce cannabis with desired characteristics. 

Compatibility with existing setup

Ensure that the LED retrofit fixtures you choose are compatible with your existing infrastructure. Consider factors such as electrical compatibility and mounting options. Compatibility and seamless integration will simplify the installation process and allow for efficient operation and control of the lighting system.

Light intensity and uniformity

Sufficient light intensity and even distribution across the entire canopy are key for optimal plant growth. Choose LED retrofit fixtures that deliver adequate light levels to meet the needs of your cannabis plants. Dimmable LED grow lights provide different light intensities tailored to plants in different growing stages. Also, factor in the light distribution and evenness to ensure consistent coverage and minimize shadowing. Doing so facilitates uniform growth and prevents any areas of the canopy from being underutilized.

Support and service

Work with a manufacturer that offers excellent customer support and after-sales service, including technical assistance and warranty coverage. A reliable support system will address any issues or concerns promptly to minimize downtime and disruptions. Professional horticulture lighting manufacturers also provide a tailored lighting plan and customized service to help you maximize efficiency and minimize costs.
