PROGROW 1800 PAR Maps

Photosynthetic Photon Flux Density (µmol/m2/s)

​

Cannabis yields are a function of light intensity. Recent 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. The PROGROW 1800 will deliver PPFD levels of 1,200 umols/m2/s, whether arranged individually or 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

​

  • Seedling - 36" to 48" hanging height, 200 to 300 umols/m2/s

  • Vegetative - 24 " to 36" hanging height, 300 to 600 umols/m2/s

  • Flower - 12" to 36" hanging height, 600 to 1,500 umols/m2/s (Note: CO2 supplementation is necessary for higher PPFD levels)

​

In order to adjust and acheive target PPFD levels from phase to phase throughout the cultivation cycle, it is recommended that growers use a PAR meter in combination with hang height and dimming. The PAR maps and tent configurations shown below are meant to provide general guidance.
