Choosing a lighting system for your application is a large investment. Knowing where to begin can be difficult. Cannabis requires high light intensities for proper development and growth and critical photoperiods to initiate specific growth stages. Having a reliable and efficient lighting system is important not only for plant growth but also for increasing yields and maximizing profits. Since P.L. Light Systems manufactures and sells both HID and LED technologies, we aren’t biased toward one technology. We can help find the right solution for your application.

Greenhouse Applications
For greenhouse applications, where sunlight provides much of the light and growers use supplemental lighting to increase their DLI and/or photoperiod, we recommend our NXT2 luminaires with HPS lamps. HPS lamps are a tried and true spectrum, with peaks in red wavelengths, used to optimize photosynthesis and initiate the flowering response in plants.
For LED technology, we recommend the TriPlane Linear RWMB spectrum, with peaks in red and blue for optimizing photosynthesis. Photoperiod should be monitored to move through vegetative to flowering growth stages.
To get the best of both technologies, a hybrid LED-HID can be used. This allows you to take advantage of the radiant heating from an HPS and extend the supplemental lighting period into the spring by using LED lights only when outside temperatures and daylight hours increase. A hybrid system also reduces the initial capex and can help further manage costs by maintaining existing infrastructure.
Indoor Growing Applications
For indoor sole source lighting applications, where artificial light is the only source available for plant growth, we recommend the NXT-LP for low ceiling or NXT2 for higher ceiling applications. HPS lamps are the tried and true spectrum for initiating the flowering response and optimizing photosynthesis during the flowering stage. For the vegetative stage, an LED luminaire is the better fit, since a broad spectrum carrying blue light supports the compact, bushy growth habit growers want before flowering.
For LED luminaires, we recommend the TriPlane Linear with daylight “broad spectrum” white light, so plants can use the wavelengths they need throughout their lifecycle. These also make plant assessment easier for workers. Photoperiod needs to be monitored for plants to move through vegetative and flowering growth stages when using a single spectrum for growth.
For close-to-ceiling applications or multi-tiered vertical applications, the VertiMax LED line is recommended.
