A lot of indoor growers are forsaking their HPS and HID lights and switching to more energy-efficient LED options available. Unfortunately, with LED grow lights, many of them are of high quality based on their LEDs alone. Unlike the HID options from 5 or 10 years ago, no “best” option will fit everyone.

Instead, you have to hunt down the LED lights that best suit your needs and your budget. LED grow lights are quickly increasing in price because of their features, long lifespan, and energy efficiency. LED grow light systems also offer an increase in sterilization, which is great for humid climates.

The Roleadro (formerly GalaxyHydro) LED systems are known for their long-lasting LED grow lights and are full of features. The features aren’t always necessary, but many professional growers find them useful. However, new growers find them overly complicated. Here’s our LED grow light review of the Roleadro LED grow light systems.

Best Features

The bestseller in the series is the Roleadro GalaxyHydro series. It relies on its massive library of features in its systems to lure people in. The best feature, without a doubt, is the dimmer switch, which allows you to adjust the intensity of the light. These are the best grow lights for indoor plants that require various amounts of light.

GalaxyHydro LED’s affordable options offer 1 or 2 dimming options, but their higher-end models offer a variety of levels to simulate the light of a day. From sunrise to sunset, the concept here is that simulating the sun’s natural motions through the sky will lead to better yields and happier indoor plant growth.

The gradual changes you can achieve through the GalaxyHydro LED top lines can simulate not only a daylight feel but also changes in the seasons. This replication allows a progressive shift in spectrum levels, and your plants will respond accordingly. It features efficient heat dissipation using aluminum heat sinks.

Many GalaxyHydro LED comes with a one-switch feature that enables growers to use the plant light quickly in grow tents, grow rooms, and indoor gardens. Like all Roleadro products, it comes with a 2-year warranty and a 30-day money-back guarantee

Spectrum

The GalaxyHydro LED has 8 light bands, but they offer a spectrum that includes red and blue spectrum light, white light as well as infrared and ultraviolet. This spectrum combination helps your indoor plants through all the plants’ growth cycles.

The spectrum quality is best explained by acknowledging which LEDs the GalaxyHydro uses. Because GalaxyHydro LED uses EpiLED lighting with 3-wattage diodes and LED chips, the spectrum shines with less interference than the indoor plant grow lights that use regular LEDs. The light from GalaxyHydro LED diffuse quickly. It comes with 165W of actual power, but is low on the actual power consumption.

Other Features

Many growers in humid environments prefer to have extraordinarily sterile lights. The GalaxyHydro LED uses a series of ultraviolet and red light spectrums that help sterilize the environment. They also have veg/flowering switches that promote your plants to grow through the vegetative and flowering stages.

Unlike many other LED light systems, the Galaxy Hydro LEDs use only a professional mix of UV and infrared plant grow light. Some systems now are using too much UV and infrared causing plants to sunburn.

The light proportion is incredibly essential, and the professional lighting mix you find in Roleadro LED systems is one of the best proportions you can find.

Cooling fans are another essential feature available in all Roleadro LED systems. They keep the entire unit cool, which helps extend the lifespan of the unit as well.

Galaxyhydro 300W LED Grow Lights Review

Galaxyhydro’s 300W LED Grow Light is one of our top picks when it comes to indoor grow lights. Whereas a lot of grow lights require some expert knowledge to set up and manage, the Galaxyhydro is perfect for both growing novices and experienced growers. It comes at a low enough price point that makes it a great starting light for anyone who is experimenting with growing cannabis for the first time.

This system is the first choice for many new growers using hydroponic systems. However, it doesn’t quite fit the bill for its price. You can pay slightly more for a much better product, or slightly lower for a very similar product.

The Galaxy Hydro 300 has three cooling systems, a dimmable switch, and full-spectrum LED lighting. There’s nothing particularly special about this light given its size and price range.

It’s one of the most budget-friendly LED grow lights we’ve found and makes a great, affordable alternative to 150W rated HPS or HIDs.

But with a lower price point, you have to expect that it may not be as powerful as some of its competitors. While it’s a great light, it doesn’t provide the maximum coverage that you would find with some of the higher-end grow lamps on the market.

That being said, for growers who have smaller grow tents or indoor gardens, this full spectrum grow light will definitely get the job done. It is an excellent choice for boosting the growth cycle of a few plants at one go.

Let’s dive into more detailed information about this model in the Galaxyhydro series and highlight some of the main reasons you would choose the Roleadro Galaxyhydro 300W grow light.

Design and Durability

PAR Output and Performance

This model has a higher PAR value and a superior ratio of the light spectrum for your cannabis plants. PAR is very impressive.

At 12 inches, you have 716 μmol m−2 s−1, at 18 inches, you have 312 μmol m−2 s−1, at 24 inches, you have 223 μmol m−2 s−1, and at 36 inches, you have 96 μmol m−2 s−1.

The excellent PAR value ensures that your plants maximize LED light absorption and increase plant canopy penetration by 20 percent.

The superior PAR value will bring your seedlings to life in a matter of days.

Spectrum

The light delivers an optimal full spectrum with the following wavelengths: 470nm, UV 380-400nm, IR 730nm, white light, 650-660nm, 620-630nm, 610-615nm, 450-460nm, and 430-440nm.

Even though the full spectrum LED is not selectable, it has the most beneficial LED light that your plants desperately need.

The red light and blue light contained in this light spectrum will fast-track the plant growth of your plants and increase yields. At the same time, the UV light eliminates plant disease by killing bacteria.

The Galaxyhydro series features a solid made from fire-resistant housing and exterior components. The unit features an on/off switch and the power outlet as well as a connection for a daisy chain and a three bass cooling system.

It’s upgraded heat sinks work in combination with high-speed bass fans that deliver excellent cooling and heat dissipation for your plants.

The professional design also adopts a hundred pieces of high-intensity Epiled LEDs rated at 3W. These LEDs are the most effective because they do not heat up quickly, like the 5W and 10W LEDs.

The Zener diode technology used protects the individual LEDs. A burn out LED will not affect the performance of the rest.

Apart from having excellent heat insulation, the shell of this indoor plant grow light is also well-protected against dampness, rust, and corrosion.

This Galaxyhydro LED design also features dimmer technology. It has a dimmer located at the back of the unit, which allows you to adjust the brightness from 0 to 100 percent conveniently.

The dimmable light setting is a very innovative feature because it allows you to control the brightness at different growth stages of your plants. You can optimize for veg and flowering stage when you need to.

We hope you found some helpful information from this LED grow light review of the Galaxyhydro 300w series. What this model lacks in actual power, it more than makes up for in reliability and affordability making it a perfect light for growers just getting started on their indoor growing journey.

GalaxyHydro 600W

The prize model of the Galaxy Hydro LEDs lower end, this system features a full spectrum grow lights while using two large fans that operate at high speeds to keep internal temperatures down.

The aluminum exterior keeps the system cool as wells. The primary feature that we find from the Galaxy Hydro LED is the UV sterilization. This model is great for beginners or hobbyists.

Conclusion

The Galaxy Hydro LEDs are the leading grow lamps for beginners and hobbyists. They’re designed with the needs of professionals in mind, but they don’t offer the size and intensity that professionals need. You can connect or daisy-chain multiple units together. However, the daisy-chaining comes with its issues. In addition to the 300w and 600w, if you need even more power, Galaxyhydro also has 1000w LEDs as well.

Many professionals desire a timed dimmer, not just a switch, and this shortcoming isn’t’ easily overlooked. The availability of different models from Galaxy Hydro LED is terrific. However, the 2best selling models are for beginner growers. If you’re looking to choose between the Galaxy Hydro 300 and 600, you’ll get a better bang for your buck from the 600.
