Apollo Horticulture GL80X5LED Full Spectrum 400W LED Grow Light for Indoor Plant Growing

A complete analysis of Apollo Horticulture GL80X5LED 400W LED Grow Light

First of all, this grow light is very affordable. But don’t let the price deceive you because the quality is top notch. Furthermore, it’s very energy-efficient which means it will also save you some money in a long run.

This is probably one of the best led grow lights you can find today and you can use it for both vegetables and flowers.

This particular model provides a full spectrum that will keep your plants happy and healthy. With 80 5W LEDs, the panel covers 3 ft x 3 ft area for vegetative phase of your plant and 2.5 ft x 2.5 ft for flowering phase.

The unit stays cool to the touch during the working hour’s thanks to an integrated cooling system that uses two big 4.5” fans and the overheating is prevented by the use of a large heatsink.

The Apollo Horticulture GL80X5LED 400W LED Grow Light has various applications. You can use it for greenhouses, grow tents, hydroponic systems, grow boxes, etc.

The LEDs (high output 5W) never work at their maximum power of 400W and that’s a good thing. You see, if the LEDs were driven at their maximum capacity they would most probably burn out.

When it comes to installation, the panel comes equipped with one set of 19” stainless steel hanging kit and a 6.6 ft power cable and it’s extremely easy to setup.

The unit has an estimated lifespan of 50000 hours.

Great PAR value

The PAR value of this unit is not mentioned in the product’s official description but the LEDs produce different wavelengths or colors of light which speaks a lot about the PAR value of the GL80X5LED 400W LED grow light.

If you want your indoor plants to grow and flourish, you must provide them with different wavelengths of light. The blue wavelength is the most important one for the growing phase while the red/orange wavelengths are crucial for the flowering phase.

With this unit, all of the wavelengths of color for the best possible PAR value are available and at your disposal.

Grow tent

The Apollo Horticulture GL80X5LED 400W LED grow light covers an area of around 3 ft x 3 ft during the vegetative stage of your plant’s growth. Flowering stage requires a bit more intensive light, so the recommended coverage area during that phase is 2.5 ft x 2.5 ft for optimal results.

If you intend to use a larger growing area, we recommend overlapping light with more panels and make sure that you avoid dark spots for the best possible results.

Hanging height

When it comes to hanging height, there are a lot of different opinions, but in the most cases, people find that the best results were achieved with the lights hung 18 to 22 inches above the plants.

On the other hand, there are some people who have reported that they achieved the best results with the lights hanging high up to 36 inches above the plants.

Whatever you do, never hang the lights too close to your precious plants. These lights are quite powerful and they can scorch the leaves of your plant and bleach them to white.

There aren’t any specifications and recommendations about the hanging height from the company unfortunately but you can always experiment and see what height works best for you.
