Which Lighting to Choose for Industrial Cannabis Cultivation?

Traditional Light Sources: HPS, CFL, and CMH

HPS Lamps (High Pressure Sodium)

HPS lamps are among the oldest light sources used in cultivation. They emit warm, orange light that promotes plant flowering. They require magnetic or electronic ballasts, with the latter being more efficient, generating less heat, and offering better power control. Due to the high heat output, air-cooled reflectors, known as cooltubes, are often used to maintain the right temperature in the grow room.

CFL Lamps (Compact Fluorescent Lamp)

CFL lamps are compact fluorescent lamps that emit light similar to natural light, supporting vegetative growth. They are affordable and easy to handle, but they have low light efficiency and a short lifespan. They are not recommended for larger grows due to their limited power.

CMH Lamps (Ceramic Metal Halide)

CMH is a newer technology that offers a full spectrum of light, beneficial for plants at every growth stage. However, they are expensive and generate a lot of heat, which may require additional cooling. These lamps are often used by growers seeking an alternative to HPS, but their popularity is declining in favor of modern LED technologies.

The Evolution of LED Technology

Older LED Technologies

In the early years of LED lamps, diodes that emitted light in a specific purple color were used. While they had some advantages, their efficiency was low, and the light was unsuitable for all stages of plant growth. Many growers who invested in these lamps were disappointed with their results.

Modern LED Technologies

Today's LED lamps offer a full spectrum of light, ideal for photosynthesis and plant growth. They use advanced chips such as Samsung or Osram, which provide high light output (up to 2.7 µmol/J) with low energy consumption. Modern diodes also generate less heat, making it easier to control the growing conditions.

Overview of Modern LED Lamps

Lumatek

Lumatek lamps, like the Zeus series, use Osram and Lumiled diodes, offering a full spectrum of light with high efficiency. These lamps are more expensive but provide excellent light quality.

Pure LED

Pure LED uses Samsung diodes, offering high light output and longevity. This brand is appreciated for its quality, although its products are somewhat more expensive.

Mars Hydro

Mars Hydro also uses Samsung diodes and offers solid performance at a competitive price. Lamps like the SP 3000 are popular among growers looking for a good price-performance ratio.

GOAT LED

GOAT lamps stand out with the best value for money. They use the latest Samsung chips, providing a full spectrum of light with low energy consumption. GOAT lamps are the ideal choice for both hobbyists and professional growers, offering excellent results at lower costs than more well-known brands.

Benefits of Using CO2

Thanks to the lower temperatures generated by LED lamps, adding CO2 to the grow becomes less problematic. CO2 accelerates photosynthesis, leading to higher yields. Using CO2 in the grow can increase efficiency, especially when combined with efficient LED lighting. Check out CO2 in our shop.

Conclusion

Choosing the right lighting is crucial for the success of industrial cannabis cultivation. From traditional HPS and CMH lamps to the development of LED technology, to modern solutions like GOAT LED, the possibilities are vast. Modern technologies, such as LED, offer full-spectrum light, energy savings, and lower operating costs, making them the best choice for modern growers.
