Red LED for photosynthesis & improved color rendition
Appendix A – Photosynthesis and Visible Light
In a separate experiment, we doubled the intensity of the LED lights (about 400 W) over the tomatoes in their vegetative phase. As with the previous experiment, the testing was done in a controlled 4x4 growing area and closely monitored.
Although the experiment is still in progress, at the time of this publication, we noted the growth of the plant. Leaves grew wider with a darker green color, indicating high levels of chlorophyll, even in the lowest tier of the plants. With this added intensity, the tomato plants began to flower in just two weeks. The flowering stage for these tomatoes began early in comparison to the plants in the previous experiment, which began to flower after four weeks. It is clear that these tomato plants benefited from the extra boost of light.

The problem is that lighting designers and horticulturalists generally do not speak the same language. Whereas we speak in terms of lumens and illuminance, horticulturalists speak in terms of photosynthetically active radiation (PAR) and photosynthetic photon flux density (PPFD). Ask for an explanation of these terms and you will hear talk of micromoles, and possibly microeinsteins, of photons. Instead of luminous flux, there is quantum flux. It can be very confusing, not to say frustrating.

In order for photosynthesis to begin, light and carbon dioxide must be taken in through the leaf's stomata, tiny openings on the surface of the leaf.

These are on two different channels. Daylight can be controlled separately from the actinics (with the use of a controller).
One channel is all the Fiji Blues and NUV long with one NP Blue. The other channel is the daylight, red and remaining three NP Blue (full spectrum)
Best LED Grow Lights 2017, for Plants, Crops and Cannabis
2058 Lumens, PAR 148 uEinsteins/sec/m2 @16 inches at maximum PUR (not CRI & other gimmicks), providing high light tropical sun natural daylight in the natural spikes needed by plants.
There is simply NO better planted aquarium LED for those looking normal natural growth (including the models #400 tile & #600 strip).
With the highest water proof rating and longest warranty and there is still NO BETTER Planted or Fish only freshwater light!!
