GROW 200 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 GROW 200 will deliver PPFD levels over 1,000 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 24" 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.
