Premium Quality Diodes

The Mars Hydro FC6500 features 2688 Samsung LM301 and Osram 660nm LED Diodes, which are known for their reliability and performance. Samsung's LEDs are widely used due to their high light output and long lifespan.


Full Spectrum Output

The Mars Hydro FC6500 features a full spectrum output, ensuring that your plants get all the wavelengths of light they need to thrive. Comprised of a patented array of Samsung 3000k, 5000k and Osram 660nm Red diodes, the Mars Hydro FC6500 has absolutely everything your plants require from tiny seedlings all the way up to big juicy fruits and vegetables. 


Hugely Energy Efficient

With a 650w power output and a daily electricity cost of £1.99, the Mars Hydro FC6500 is one of the most efficient LED grow lights available. At less than £2 per day to flower, the Mars Hydro FC6500 can complete an 8 week flowering cycle at a cost of just £112. This means that the Mars Hydro FC6500 is an investment in your grow room that pays for itself very quickly indeed. 


Advanced Heat Management

The Mars Hydro FC6500 features a clever passive cooling technology to keep the temperature in your grow area as low as possible. The light bars are specifically engineered to radiate any excess heat upwards and away from your grow space. 


Super High Yield

With its super high output and well balanced spectrum, the Mars Hydro FC6500 enables even beginner cultivators to produce bumper harvests of resin rich produce time after time. Advanced gardeners have been reported to produce yields of over 3.0g per watt with this little beauty. Incredible. 


Fully Controllable

The Mars Hydro FC6500 is fully dimmable and allows growers to adjust the light intensity with ease and precision.  This enables growers to optimise their environment and also keep costs as low as possible for those early few weeks. 


Life Expectancy

With a life expectancy of around 50000 hours, the Mars Hydro FC6500 is built to last, reducing the need for frequent replacements and further lowering long-term costs.


Daisy Chain Ready

Cultivators can connect up to 30 Mars Hydro FC6500 fixtures together, making it perfect a perfect LED Grow Light for cultivators looking to expand their grow space over time.


Smart App Controlled

In a giant leap forward in LED Grow Light Technology, Mars Hydro now introduce Smart Control as standard on their new FC Series. This means that cultivators can control their LED Grow Light using their smartphone without needlessly disturbing their grow area. The light cycles and features can be easily programmed through the app, providing flexibility and control over your grow setup like never before. Superb. 


IP65 Waterproof

With an IP65 waterproof rating, the device can operate efficiently in high humidity environments.

The Mars Hydro FC6500 seems to be a well-designed, powerful, and efficient solution for indoor growers. With its awesome Smart Control feature and incredibly well balanced spectrum, this really is a great light that will delight even the most discerning cultivator.
