Roleadro GalaxyHydro 300W LED Grow Light Review


This sturdy, well-built Roleadro GalaxyHydro 300W LED grow light measures 15.5 inches long by 8.3 inches wide by 2.4 inches deep and weighs about 7.6 pounds. It comes with a power cord and a stainless steel hanger, as well as a 2-year warranty. It has 100 high power Epiled 3W chips which produce bright light and lots of infrared light, as well as being incredibly energy efficient. Like most LED grow lights, it has a lifespan of up to 50,000 hours. This lamp has heat sinks and UL approved built-in fans to reduce heat and noise, and multiple lamps can be linked together in a daisy chain if you are growing lots of plants.

It is recommended to keep the lights on for between 10 and 16 hours a day, and to change the hanging height from 36-40 inches during germination and for seedlings, to 18-25 inches during the vegetative stage, through to 15-18 inches when the adult plants begin to flower. The coverage of the GalaxyHydro ranges from three square feet during the vegetative stage (when the lamp is hung further from the plants), to two square feet during the flowering stage (when the lamp is closer to the canopy).

Light Spectrum

This LED grow light offers full spectrum light of wavelengths between 430nm and 740nm, including ultraviolet light and infrared. It has more blue and red LED bulbs, producing more blue and red light (and less white light) than most LED grow lights. This will benefit your plants, as they need both blue and red light to grow and develop lots of buds, whereas white light is not as productive.


Efficiency is an important factor to consider when choosing an indoor grow light. Lamps that are highly efficient will use less power (reducing your electricity bills) whilst still be producing bright, full-spectrum light for your plants.


The Roleadro GalaxyHydro is hugely efficient with its Epiled 3W chips, and can, in fact, produce the same bright light using only 130W that an equivalent HPS lamp would need about 300W to produce!



At under $100 (USD), the Roleadro GalaxyHydro 300W LED grow light is excellent value for money. It is sturdy and long-lasting, providing your plants with all the different light wavelengths they need to grow big and strong and to yield good bud. The lamp’s high energy efficiency not only makes this light a good buy but also cheap to run, as well as being kinder to the environment.

If you are a beginner grower and/or only want to grow a few plants, then this light is perfect for you. The Roleadro GalaxyHydro is a small, efficient and affordable grow lamp that won’t let you down.
