PAR Grid Chart at 24”


gavita 1700e and cultiuana ct800 PAR Grid Chart at 24 foot

When both lights are suspended at a height of 24 inches, we can observe the PAR chart provided below for each light.

Gavita demonstrates high light intensity, while Cultiuana also performs impressively in this aspect, with even higher data. Based on the PAR chart data for both lights, we can draw the following conclusion:

Cultiuana offers greater PPFD data, leading to various advantages:

First, during the flowering phase, indoor plants receive increased light, resulting in enhanced yields. Secondly, it enables a reduced harvesting period, saving cultivation time. This empowers growers to cultivate an extra crop within a single year.

Second, when growers use CO2 supplementation for their plants, they need to provide a PPFD (Photosynthetic Photon Flux Density) of more than 1100 μmol/m²/s.

But unfortunately, based on the data we have from the graph, Gavita's 1700e may not give enough PPFD when CO2 is used, which means the plants might not get the ideal light levels for maximum yields.

On the other hand, Cultiuana CT-800 shows 1100 μmol/m²/s higher PPFD values, which is really great for growers who use CO2 supplementation.

So, for growers relying on CO2 supplementation, it's important to consider that Gavita's 1700e may not meet their specific PPFD needs.

Third, another advantage is that CT-800 can be hung higher. This means it can cover a larger area, so with the same cultivation space, one light can take care of more cannabis plants, and this brings better economic benefits.

the spectrum of both Gavita and Cultiuana LED lights

The graph above shows the spectrum of both Gavita and Cultiuana CT-800 LED grow light. They follow the typical pattern of full-spectrum LEDs with stronger intensity in the blue and red parts of the spectrum.

Each light fixture uses different LED diodes, including a variety of color temperatures for the white light. However, they both maintain a broad full spectrum across the entire PAR range from 400nm to 700nm, with enhanced power in the blue and red regions.

Interestingly, when we look beyond the PAR range, the Cultiuana CT-800 stands out by emitting a stronger amount of infrared radiation.

730nm wavelength light belongs to the far-red light spectrum, and its effects on indoor plants cultivation can be seen in the following aspects:

Flowering regulation: Far-red light at 730nm can help plants adjust their photoperiod, leading to an accelerated transition into the flowering stage. Introducing a moderate amount of 730nm infrared light during specific periods can promote cannabis growth and flowering.

Endogenous hormone balance: The influence of far-red light on plant growth regulators such as auxins and gibberellins help facilitate plant growth and flowering.

Photomorphogenic response: Indoor plants exhibit photomorphogenic responses, where different light wavelengths can stimulate specific growth processes. For instance, 730nm light can reduce the plants' elongation response to light, resulting in a compact structure during indoor cultivation.

It is important to note that relying solely on 730nm light is not sufficient for indoor plants cultivation, as it should be combined with other light wavelengths.

For example, blue light and red light (with bandwidths of 400-500nm and 620-680nm, respectively) play crucial roles in photosynthesis, ensuring normal plant growth.

In summary, 730nm light serves as a supportive factor in indoor plants cultivation, promoting growth and flowering through the regulation of the entire growth cycle and hormone balance.

It should be used in conjunction with other light wavelengths in an indoor spectral adjustment system to achieve an ideal light environment.
