At least, not the kind of light spread that is really useful. So, here is how the title is truer than not. First, with stationary indoor grow lights, the idea of indoor grow light spread is something we might assume. And, sometimes the grow light system is marketed as strong enough to reach any nearby plants. Or, it’s marketed as having directional qualities with some of the light bits (scientific term) going off sideways.
Even good grow lights are indoor grow light spread challenged
So, here’s the thing. Plenty of grow light systems are super high quality grow light systems. And, that can certainly be said of some of the amazing double ended grow lights out there. It’s also true with some of the quality LED grow lights available from the brands we love. And there are others such as plasma grow lights that can be powerful in intensity. Plus, we have the UV and UVB grow lights that are used to speed up yield and used to fight powdery mildew. Each of these grow light systems are brilliant in what they offer. But, what about indoor grow light spread? And specifically, how can we get these grow light systems to really work for that effective indoor grow light spread that we’re after?
Hard, cold, scientific fact
Let’s first look at any claim that a given grow lamp is already powerful enough for achieving quality indoor grow light spread. To that point, no, it’s not. There is no such thing. The best ppfd in the world will never perform in a way that reaches plants the next group over effectively. And, it’s the same with indoor plant light that’s distributed at angles as directional grow equipment lighting. With either scenario, it all comes down to the science and specifically, it comes down to Inverse Square Law. The “law” word, only with a capital, means it is one hard, cold, scientific fact. Inverse Square Law states that indoor plant light decreases geometrically the farther away it is positioned from the plant canopy. See how this grow equipment factor affects ppfd numbers.
More distance means much worse and in a big hurry
So as the opposite way of how we should be doing this, we tend to position stationary grow light systems about three feet from the plant canopy. And, sometimes we put our grow equipment lighting even farther away. That’s because we are trying for some of that indoor grow light spread. It’s pointless and hopeless, sorry, and here’s why. The farther away we put our grow equipment lighting; the weaker the indoor plant light. And remember, it’s geometrically diminishing for our grow lamp power. What this means is, with any kind of distance, it gets much worse and in a big hurry.
The biggest waste of growing equipment potential
Here is a good way to see this growing equipment conundrum. When our grow light systems are five feet above the plant canopy, we get exactly 50% of the power for those grow light systems. Even at three feet above the canopy, we are using a fraction of the grow lamp potential. So, it’s a waste. It’s a huge waste of light spectrum quality and all the good stuff really. It’s probably the biggest waste of grow equipment potential possible in the grow room setup.
Stationary grow light hard and fast rules
Also to know, part of the problem is stationary grow light systems have stationary grow light rules. Some of those grow light rules state that a closer stationary indoor plant light will burn and be too intense in one spot. And, a closer stationary indoor plant light will be too directional with one plant on and one completely off. These are growing equipment rules to be broken and there is a better way. And, we shouldn’t be lifting our indoor grow lights as we’re aiming for a little ineffective spread. The only effective way to get true indoor grow light spread is to use grow light movers.
No hot spots and more leaves getting quality grow light system interaction
Grow light movers let us get around Inverse Square Law because we can now get the indoor grow systems of our grow room setup much closer. And, that’s without any hot spots. That can be done to move a single indoor grow light with a LightRail 3.5 Kit or a LightRail 4.0 Kit. And, it can be done to move each pair of two grow lights with a LightRail 4.20 Kit. So, we can do this without the burn and the zoned light overkill no matter the LightRail system. When we get our grow light systems closer, we get maximum grow lamp benefits.
When we do this, the power of our grow light systems are realized as close to 100% potential as possible. Hey, that’s way better than 50%, don’t you think? With grow light movers, each growing equipment lamp moves along the light mover rail, interacting with each plant surface strongly but intermittently, and at just the correct amount of time.
Just move the grow lamp this far
No, we don’t move each grow lamp too far but just maybe three feet (one meter), stopper to stopper. And to picture that action at the stopper setting, each indoor grow light stops at the middle of the light at each stopper. So, half the indoor grow light goes beyond the stopper setting. And, that’s for both directions of travel. Plus, while our grow light system is traveling along the light mover rail, the indoor plant light is angling in to reach all the leaves. That’s very sun-like, by the way. And, the plant’s leaf receptors that receive light actually open more when the light is fiercely strong but intermittent. The opposite is true with stationary grow light systems that beat down on the same plants from overhead while the next plant over remains starved for some of that intensity.
Grow light movers give us these supercharged results
Grow light movers give us the only real and effective indoor grow light spread. There, I said it. And, we get to keep all the quality grow lamp intensity that our indoor grow lights can deliver. So, for the thinking that stationary grow lights can give us any real indoor grow light spread; it’s not fact-based, at least not for the kind of results we want to see. We can, however, take the best grow lights out there and make them that much more powerful. And by moving them, it results in significant yield increases. So, here’s the smarter way. We can unleash the potential in our grow light systems while getting effective indoor plant light spread, both at the same time. And, that dual benefit can be achieved, very simply, by using light movers.
