How To Choose The Right Lighting For Your Marijuana Grow Room

galaxyhydro led grow light reviewIt was tons of fun setting up our mini 3×3 grow tent review operation with this grow light. For our Galaxyhydro 300w review we wanted a bit of a challenge. So we took it upon ourselves in this grow to utilize a tight spot and to effectively grow 2 plants with the Galaxyhydro 300W Led Grow Light and that is what we did.


Galaxyhydro LED Grow Light Review

HydroGalaxy 300w reviewThere are some good theories about how and why the red and blue light spectrum of the Galaxyhydro 300w galaxy hydro led lights effect plant growth for the better. Because of this, I was thrilled to finally set up our small 3×3 grow.

GalaxyHydro LED Growing Results

The results proved wonderful after we got through some tight technical requirements. Again we had a small space to grow and because I decided to use my small grow tent the heat was our biggest trouble. Typically LED’s lighting does not run to hot, but because this grow started in summer, the ambient heat plus LED’s constantly running caused the little tent to reach almost 100 degrees.

When you purchase this LED be sure to include a couple of good fans if you are using a small grow tent in a small area.

Galaxy Hydro Review:

Galaxyhydro LED’s with this lamp contains a mixture of red, blue and white light however pushing more towards the red scale of the spectrum. This means the ability to grow bushier and more sturdy plants is obvious.

If you have noticed some limp and listless plants, it might be because of your white light wavelengths not reinforcing the plant’s rigidity.

Weighing in at around 5 and a half pounds, the Galaxyhydro comes backed with a great warranty should anything happen to its operational value.

3W LED chips gives this lighting rig energy savings and very decent light output centered around infrared that promotes plant growth. The good balance of red and blue light are what puts this up there in good graces for me. The plants seem to like it as well.

The Best Features Of The Galaxyhydro LED:

  • Infrared Spectrum Promoting Better Photosynthesis
  • Perfect Blue, Red, White Balance
  • Well Constructed
  • Brightness Output Is Awesome
  • Easy on The Energy Bills
  • Built-in Fans That Are Fairly Quite (Add more if you intend to grow in tight areas)
  • 90-degree lenses, meaning less grow light loss through directional lights (120 degrees optional)

Your plants will enjoy this light and hopefully grow you big fat nugs. The lamp was great for 2 of our strains that we grew. Our test seed for this review was the outstanding Hindu Kush. The veg and bloom phases seemed to produce a sturdy and healthy plant, once we regulated the temp properly from the LED grow light.

Easy to Hang and Control Temperatures

Typically 16 hours, even with an LED can peak the temps. Our lighting was hung roughly 20 inches from the cannabis canopy and was easy to adjust due to the light weightiness of the LED itself.

If you do have a bigger indoor growing area and need more light output then the Galaxyhydro has the ability to daisy chain which is a great feature. Essentially you can string up more lighting and they connect to one another without the need for extra outlets and tangled cordsgalaxyhydro daisy chain

Overall, I found this a good led grow light at a very reasonable price. The final product resulted in some great plants that were full of flavored and packed a punch as the Hindu Kush should.

Galaxyhydro LED’s Are Proven

If you are in need of a well built and decent spectrum led grow light than you might be impressed by the optical spectrum of light the Galaxyhydro 300w (see also Kind K3 Series 2 XL300) produces for strong and healthy plants due to its red and blue balanced lighting. This coupled with its energy savings makes our review experience a positive one.  We get the impression that this LED is built to last a lifetime.  A wallet-friendly light for any indoor growing enthusiast, the Galaxyhydro packs a big punch for such a small light.

The best part:

If you need more light, the daisy chain function does the trick and is easy to set up. A word of caution. Keep the lights far enough above the flowers because these are powerful lights. Easy to do with a proper pulley system.

Our recommended grow light distance for the Galaxyhydro 300w:

  • For germination hang roughly 50 inches above your grow
  • The vegetative state should be anywhere between 40 to 48 inches
  • The flowering stage should fall between 32 and 42 inches depending on your plant’s tolerance

I hope you enjoyed our Galaxyhydro LED grow light review as much as we enjoyed doing this grow.



1. Is a 300W LED grow light good?

A 300W LED grow light is a good option for someone who is looking for an efficient and affordable grow light. LED grow lights use less energy than traditional grow lights, and they also produce less heat, which can be harmful to plants.

2. How many plants can I grow under 300W LED?

You could grow about 10 plants under a 300W LED light.

3. How many watts does a 300w LED use?

300 watts is the equivalent of using three 100 watt incandescent light bulbs. LED lights to use about 1/10th of the energy of incandescent bulbs, so a 300 watt LED would use about 30 watts of electricity.

4. What LED bulb is equivalent to 300 watts?

The wattage of a bulb depends on its size and type. However, a 300-watt incandescent bulb is equivalent to a 23-watt LED bulb.

5. Can normal LED lights grow plants?

There is some debate over whether or not LED lights can be used to grow plants. Some people say that the light spectrum emitted by LED lights is not ideal for plant growth, while others claim that LED lights are just as good as traditional grow lights. In my experience, I have found that LED lights can be used to grow plants, but they may not produce as many blooms as traditional grow lights.
