The Grow Light Science PROGROW 4200 HB LED Grow Light is an ideal top lighting solution for maximizing yield in commercial or residential crops cultivation. It offers scalable form factor for multiple grow room and grow tent configurations, delivering 4,209 umol/m2/s of PPFD with excellent uniformity. With top-notch PPF, spectral distribution, and efficacy, it delivers great results while being affordable. Try risk-free for 120 days.
The PROGROW 4200 HB model is a full-cycle, high-output, top-lighting solution for indoor commercial crops cultivation (not suitable for residential applications). It produces 4,209 umol/s of PPF and is designed to deliver PPFD levels of up to 2,000 umol/m2/s with excellent uniformity.
The 4200 HB's form factor allows for scalability and multiple grow room configurations where photosynthesis and yield maximization is the aim. Top-shelf light output (PPF), spectral distribution, and efficacy will delivery amazing results with modest impact on your wallet.

PROGROW 4200 HB Light Intensity
Plant 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 1800 and PROGROW 2100 close-proximity solutions, the PROGROW 4200 HB would typically be mounted distances of six 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.
