Grow Light Science PROGROW 640 LED Grow Light

Grow Light Science PROGROW 640 Watt LED Grow Light

The PROGROW 640 is a full-cycle top lighting solution for commercial or home indoor gardens or grow operations.  The 640's form factor allows for scalability and multiple grow room and grow tent configurations where photosynthesis and yield maximization is the aim.  The PROGROW 640 delivers high PPFD levels for use with or without CO2 supplementation. Top-shelf light output (PPF), spectral distribution, and efficacy will delivery amazing results with modest impact on your wallet. 

Key Features

• GLS HI-RED spectrum
• Top Bin LEDs
• Built in dimming control knob
• Dual RJ12 Ports For External Control
• High CRI - 93
• 5 Year Warranty

PROGROW 640 Light Intensity

Crop yields are a function of light intensity. Recent studies show that PPFD levels up to 1500 umols/m2/s will generate a proportional increase in yields as long as other critical inputs are kept in balance. These include CO2, water and nutrients. The PROGROW 640 will deliver PPFD levels in excess of 1000 umol/m2/s whether it is arranged individually or in a multi-unit array. We recommend that all growers study and experiment within their grow space to come up with 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.
