Product Description

The Sol 9 LED Grow Light is an engineering marvel, utilizing the latest Integrated LEDs to deliver a concentrated beam of light so bright we named it after the sun.  Sol 9 is designed for use in a 4' x 4' area, with tested PAR output matching that of a 750W-1200W HPS!  Our refined and Patent-Pending 4th 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 Fusion Reflector was developed specifically for this purpose, blending and focusing 100% of the output from our LEDs into a concentrated beam of light.  Unlike other LED Grow Lights, Sol uses no glass or acrylic lenses, which can block up to 10% light transmission with each layer.

Sol™ LED Grow Lights are an entirely new breed, with the same Hydro Grow performance, quality, and reliability, that 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, we are proud offer the next generation of LED Grow Lights to the masses.  Purchase a Sol 9 today and experience the amazing power of the sun in your indoor garden!

This light works perfectly, it's full spectrum and deep penetration is exactly what's needed to get the best out of your plants. The only complaint I have is the sound which is loud but not unreasonable considering there are 9 fans in it. Still an amazing piece of technology, hat's off to these people for making a great product.

Used it the first time = terrific. Shut down for awhile, started up again for 2nd time and the center light will not turn on. Very upsetting!

The Sol-9 from HydroGrowLed sets a new bench mark in LED technology, I was very sceptical when i first heard about the next generation of LEDs, but i shouldn't have. The lght delivered a huge harvest of 487g in 70days. It also seemed to have none of the Cal/mag problems that LED growers find from time to time. All in all this light performs spectaculary, i highly recommend it.

The verdict is still out. Fruit looks great as it is ripening. My only concern is the finished weight. That will be the difference in a good rating versus excellent rating.

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.
