Product Description

The 84X-PRO LED Grow Light is the most powerful grow light in the world for a 2' x 2' area, with tested PAR output matching that of a 400W HPS! Our refined and Patent-Pending 3rd Generation spectrum features quantum balancing to ensure lightning fast growth rates, record breaking yields, tight internode spacing, super-dense flowers, and fruits so monstrous you'll bring all your outdoor plants indoors!

Spectrum is only half the equation to enormous yields however, because light must be delivered efficiently through plant tissues at high intensities to ensure optimal penetration/absorption. Our Patent Pending X2 lens was developed specifically for this purpose, and is the most powerful optic ever invented for LED Grow Lights. Data proves the X2 lens provides an astonishing 569% higher light intensity compared to the same light without the X2 lens, a feat the competition has been unable to duplicate.

X2™ LED Grow Lights lead the world in performance, quality, and reliability, which has been proven time and again by third-party testing and real-time output data. Thanks to our ever-growing engineering and development team who work continuously throughout the year advancing our technologies, we are proud to say that X2 LED Grow Lights are the most powerful horticultural grow lights in the world. Purchase a 84X-PRO today and experience the pinnacle of growing technology in your indoor garden.

Photosynthetically Active Radiation (PAR)

Learn more about PAR

About PAR: Photosynthetically Active Radiation (PAR) specifies the spectral range from 400nm to 700nm that photosynthetic organisms use to process photosynthesis. Photosynthetic Photon Flux Density (PPFD) measured in micromoles per meter squared per second (µmol/m2/s) quantifies the number of photons (or micromoles) in PAR that are available for plants to conduct photosynthesis.

This light was purchased in 2011, and I have really enjoyed having it. However, it did take me some time to learn how to maximize the power of this light. As I experimented with it, I found that one plant (12''-24'' from canopy) under this light works best in my small space. As any grower knows, one plant is a huge risk. So, I had to invest in a couple more lights, and it was well worth the investment. Today (Jan.19 2016) was the first time that I have had any problems with this light. Hydro Grow makes it very simple to replace, and even upgrade the PCBs on each of their lights.

This little light is a POWER HOUSE. I have been growing with this light for a year and so far it has exceeded my expectations. Goodbye hps/mh and fluorescent bulbs, Hello LED Power. I'm sure my skill set has changed since I first began growing inside but I can honestly say this light has beat out every other kind of non-LED light I've purchased. My first run at growing indoors was with a 600 watt hps/mh. That sucker was HOT and raised my electric bill significantly. Now I have the 84X-PRO. Next to no heat, energy efficient, and penetrates like a bullet. The initial investment sucked but after growing with it I've realized it was worth every penny.

Felicito a quienes lo han desarrollado. He obtenido excelentes resultados. Además, los chicos de post.-venta lo hacen muy bien. Tuve que recurrir a ellos por luces de repuesto. Me las enviaron a Chile cuando estaba a punto de terminar la garantía, y ni siquiera me cobraron el envío. Vaya amabilidad. Estos muchachos sí que trabajan bien. Ahora estoy esperando más luces de repuestos (no duran para siempre) y estoy convencido de que llegarán, y aun buen precio. :) Saludos y gracias por el excelente producto

But a noisy fan. It would be nice with a more quiet one. There is good fans with high effect and low noise level out there (-: Cheers.

Hi Cammie. I'm SO IMPRESSED with the 84 X2Pro that I've just ordered a 21X2 Pro. Thanks so much. Your lights are incredible!

Hi, just writing to let you know how impressed I am with your lights, INCREDABLE!!! They are so bright (can't wait to try the X2 Pros). I bought 2 84X Pros and am doing a continous harvest so I'm not sure how to calculate GPW, but I will say the flower density is way better than my 400w HPS.Shorter internodes,alot less heat, very healthy, and fast growth. Did I mention denser? Wish I had more coverage, maybe the new lens will help. Thanks hydrogrow for a great product! mike

Remember, you can never get back the time or the harvest you lost
to your HIDs
but you can always get your money back with Hydro Grow.
