What kind of light does VIPARSPECTRA 300w produce?

Left: Spectrum Right: Footprint

The graph to the left demonstrates wavelengths in which the lights are emitted. While the figure to the right is called a distribution footprint. The graph tells us that the light is strongest at the blue of the spectrum, while less powerful at the red side of the spectrum. The distribution map on the right indicates a footprint over the area in which the light falls if you hang the fixture 24” above the plant. while looking at the purple picture to the right side, it is important to pay attention to the small numbers within the square. These number indicates the amount of power that falls on a specific point. Naturally, higher numbers mean that light reaches better at a given falling location. Thusly the best coverage potential of the light is covered by the intense purple circle.

How does VIPARSPECTRA 300w affect your plants?

Plants prefer different light based on its current stage of growth. The blue end of the light spectrum is preferable in the early life stages. Meaning from seedling to end pre-flower. Whereas plants tend to absorb more light from the red end of spectrum once it starts flowering. The blue and the red colors of led grow lights are designed to mimic seasons. During spring the light consists of more blue as opposed to falling where wavelengths with the red spectrums are more dominant.

 

When is this LED grow light the best choice for purchase? – Amount of plants to grow and grow area size

Flowering plants tend to get wide as well as tall depending on plant type and breed etc. This means the flowering plant will most likely extend further than the core cover range of 2×2. And given the fact that this particular led grow light emits mostly blue light, we recommend you buy the VIPARSPECTRA 300w if you are looking to nurture a couple of early stage plants in a smaller grow tent area of approx. 2×2 or the best grow box of your choice.

Even though the 300w is the best choice for vegging, it does not mean that it is impossible to grow a full plant. The light is just not well designed for plants in the flowering stage, if you are looking to grow a plant with a single LED grow light, then the VIPARSPECTRA 450w is a better choice due to its switch function.
