led grow lights reviews
Whilst it is almost certain that every last indoor grower is only too well aware of the introduction of the LED grow lights reviews, what is less certain is any agreement as to whether this lighting technology is actually worth the candle.
In principle, LED lights can target just those very specific wavelengths of light that are actively involved in photosynthesis. This is in contrast to conventional high intensity discharge lamps that adopt the carpet bombing technique and blast plants with every wavelength going – the idea being that at least some of this does some good.
However, early LED grow lights reviews just didn’t deliver on this promise and the empirical results were disappointing. So what went wrong?
Well this of course marks the point at which all reasoned debate descends into religious warfare. Many folk concluded that the technology to selectively target chlorophyll absorption peaks was pseudo science on a par with magnetic water softeners and remain emotionally wedded to that position to this day.
Others realized that there was in fact nothing at all wrong with the idea, just that in order to implement it effectively would require substantially more power than early LEDs offered. And in due course the “hi power” LED became generally available at affordable prices.
These are 1 watt (or occasionally 2 watt) LEDs clustered into arrays that deliver a great deal of light that crucially also has sufficient penetrative power to drive photosynthesis. More recent tests using these new LED grow light systems clearly demonstrate their efficacy.
However the skeptics remain, well, skeptical. For a start the new light modules don’t actually “appear” to be very bright and they consume suspiciously small amounts of heat.
There are however perfectly good explanations for this:
- firstly, since they are only emitting light in quite narrow bands of the blue and red parts of the spectrum then less total “white” light is indeed being produced, because it is totally redundant anyway;
- secondly, LEDs generate light directly (by stimulating electrons to release photons) and not as a byproduct of heating a filament or gas which means they genuinely do require much less power to produce the same amount of light.
In many ways, LED grow lights are not unlike early computers which in theory were capable of displaying graphics and playing sound but lacked the horsepower to actually do so effectively. But as the technology gets improved then so does the ability to deliver on promises and much the same applies to LED technology as applied to grow lighting.
