Lighting Plans

Cannabis yields are a function of light intensity. Many studies show that PPFD levels as high as 1,500 umols/m2/s will deliver a proportional increase in yields so long as other critical inputs are kept in balance. These include CO2, water, and nutrients. Some growers are enjoying even greater yields with PPFD levels as high as 2,500 umol/m2/s (similar to the intensity of the mid-day sun in the tropics where strains of sativa sub-species tend to thrive) for limited amounts of time at certain periods in their grow cycle. The PROGROW 4200 HB will deliver PPFD levels greater than 2,500 umols/m2/s, when arranged in an array of multiple units. We recommend that all growers study and experiment within their grow space to devise the best combination of inputs. 


Recommended Hanging Heights and PPFD Levels

The PROGROW 4200 HB can be arranged in multiple configurations for commercial indoor growing or greenhouse application. Unlike our PROGROW 2100 close-proximity solution, the PROGROW 4200 HB would typically be mounted distances of four feet or more above plant canopy to deliver good uniformity.  Fixture quantity and layout is tailored to each project depending on PPFD targets. We offer complimentary lighting plan development using AGI32 engineering software.
