On grow light movers, each grow light is briefly angled indoor plant light as it moves off center. This grow light interaction on LightRail light movers is subtle and, at the same time, powerfully effective for growth rates and yield numbers.
Closest to duplicating natural sunshine
First, indoor plant light that is intense but intermittent is closest to duplicating natural sunshine. And, that is actually how plants have best evolved to use the energy of light. Leaf Area Index and the photosynthetic light-response curve help to explain that there really can be too much of a good thing when it comes to indoor plant light. The plant receptors will actually shut down when bombarded. But, conversely, strong but intermittent grow light interaction will make the plant surfaces more receptive. The plant receptors will open more. As a result, more of the good grow light spectrum numbers are better received. And, that’s with that intermittently angled indoor plant light.
No grow light hot spot, closer and with better results
In addition to the angled indoor plant light benefits, we can also get our indoor grow lights much closer. And, that’s when they move along the light mover rail. That’s because a moving grow light can get that proximity without the burn or the damage. By the way, this is the opposite of what grow light companies will tell us. But, their grow room or greenhouse setup instructions are in terms of stationary grow light restrictions. However, when we take those same grow lights and we move them on LightRail light movers, we see this. We can get much closer and with much better results.
Perfectly spread ppfd
That closer more powerful grow light interaction on a grow light mover can get 3,000 PAR right to the canopy. And in terms of ppfd, we get these numbers. We can get 460-616 ppfd uniformly along a 5+ foot (2m) canopy area at a 20-inch distance. At a 15 inch distance, we can get 720-850 ppfd, uniformly across the canopy. Or, we can get 338-484 ppfd uniformly along a 5+ foot canopy area at a 25 inch distance. If we tried this with a stationary grow light, and we did, we would have the following. At 20 inch distance, it would be 1472 in the middle and 122 at the outer 5+ foot perimeter. And, at 25 inches is would be 942 in the middle and 148 at the outer 5+ foot perimeter. And, for either stationary grow light configuration, it would be never changing for those numbers. That’s both for the middle and for the outer perimeter.
At five feet above, a grow light now has only half its potential
The alternative would be to take these stationary grow lights that cannot perform up close and move them to three, four or five feet away from the canopy. Plenty do, but the problem is, at five feet distance, we have now cut our grow light energy strength in half. It’s an Inverse Square Law effect that basically explains how grow light strength is diminished geometrically with distance. So, a quality 1,000-watt full spectrum grow light positioned at 5 feet does this. It is made ineffective. And, it is no longer equivalent to 1,000 watts and it no longer has those good ppfd numbers. At five feet above, it now has only half its potential.
More leaf area using this better grow light towards energy conversion
So, going from stationary grow lights to LightRail light mover grow lights will address these obstacles. It can be a LightRail 3.5 Kit, a LightRail 4.0 Kit or a LightRail 4.20 Kit. Angled indoor plant light is definitely a significant part to this grow room or greenhouse equation. Beyond the strong but intermittent indoor plant light as the best for plant receptors, we are also doing this. We are reaching more interior plant surfaces with this better grow light. A moving indoor plant light has more grow light penetration to those lower leaves. And, that translates to more leaf area using this better grow light towards energy conversion.
Close grow light interaction as intermittently angled indoor plant light is optimal
Close grow light interaction as intermittently angled indoor plant light is optimal. And it’s the only way our plants can best use the light energy that our grow lights have to offer. When we move our indoor grow lights on grow light movers, we have a double benefit. And, those advantages are a closer more intense indoor plant light that is also an intermittently angled indoor plant light. It’s a two-part effect that cannot be duplicated. In other words, we can only get this with LightRail. And, these very advantages make growth rates faster and yield numbers increase. This change optimizes our grow room or greenhouse results significantly.
