Average PPFD in a 4x4 tent: 1109 umol/s/m2
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 640 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.
