The numbers tell the story. We can talk PAR, but ppfd is more telling in that it is the number of photosynthetically active photons that fall on a given plant surface. And, that’s per second. So, this is using more concise language than PAR, although PAR numbers give us a good idea of where we are, as well. Ppfd is seriously interesting on a grow light mover in that we can look at the data two ways. First, we can look at the hard data of the light mover grow light ppfd readings. And, that’s compared to stationary grow light ppfd readings, see chart above. Then, we can look at the plant surfaces in a bigger, more comprehensive way. And, this second grow equipment variable of the light mover grow light ppfd readings on that bigger scale is as remarkable.
First, let’s look at the simple hard data. The grow light was a 1,000 watt double ended indoor grow light and everything was kept uniform. The only grow light system change was one series used a stationary grow light and the other used that same grow light on a LightRail light mover. And, we can see the grow light system readings per distance from the canopy. We can also see the horizontal distance of grow light system coverage at 60 inches, or 5 feet (1.5m). And, we can see what those realized grow light effects are for those perimeter grow light system outer areas.
The why of faster growth rates and higher yields of a moving grow light system
Looking at the light mover grow light ppfd readings, we can see the reasons for the results. It tells the story of no hot spots, so no stress or damage for the plants in our grow room setup. It also tells us the story of more even indoor plant light coverage. And, it tells the story of why growth rates are faster and why yield numbers are higher with a moving grow light system. We have basically supercharged our indoor grow light by making the simple change of moving it. And, notice this. We are effectively covering more area per grow light. So, we are more efficient and more effective for outcome, at the same time.
Grow light movement to more leaf surfaces and at just the correct period of time
There is one other very important detail to point out for the grow room design of moving grow lights. That is back to the definition of ppfd, that being the measurement received on a given plant surface. So, look again at the good ppfd numbers for the LightRail results. We can get those better light mover grow light ppfd readings, not just to the canopy, but throughout the plant. In other words, we reach more plant surfaces with this better quality of light. It can be with a LightRail 3.5 Kit, a LightRail 4.0 Kit or a LightRail 4.20 Kit. That’s as our indoor plant light is overhead but then is slightly off-side angling in, and then is overhead once again. By this grow light movement, we are reaching more of the middle and interior leaves. And, this is grow light interaction at just the correct period of indoor plant light time per surface.
Light mover grow light ppfd readings – The numbers tell the story
The ppfd difference with LightRail light movers is dramatic. And, these numbers can be duplicated very easily with any study. It’s the LightRail difference. It gives us more coverage and better coverage with our indoor plant lights. Plus, that grow light system coverage is now perfect for the ppfd numbers that we want. The numbers tell the story. We get much better results for growth rates and yield output. And, we get an evenness of canopy coverage as well as evenness of grow light penetration. And just as importantly, we cover about 30% more per grow light, so this is an efficiency move, as well. Grow light movers allow us to get the most out of our grow light systems, and the ppfd readings tell that story the best.
