What wavelength or spectrum your LED grow lights offer your marijuana is of paramount importance to your yield. The most expensive LEDs are white, offering a broad spectrum of light like the sun cover much of the visible light spectrum. You need white LEDs! If light orbs video you see an LED grow light with just red and blue lights you are not going to achieve a high quality grow at all as the white LEDs are so much closer to mimicking the sun. The table below outlines the different GaAs versus the color and wavelength they produce.
March the 30th 1990 saw members of the Belgium public observing a large black triangular object navigating without a sound over the Belgium city for over 5 minutes. Some of the witnesses were local police officers who observed the object hovering over and around a block of flats and recorded that the object omitted a 'red glowing disk of light from its centre which flew down to the ground and darted around several buildings before disappearing'. The Belgian Air Force scrambled several F-16 fighter jets to pursue the craft given it was observed upon the ground radar systems.
After regaining his composure, the witness moved his truck forward about 15-20 feet. It was then that the man saw the object now behind him in his rear view mirror. The object looked similar to the object that he had initially seen, but couldn’t be sure that it was indeed the same triangular object. The man parked his truck and exited the vehicle to obtain a better look at the mysterious device. The object was directly behind him and about three hundred fifty feet in the sky. Within about 30 seconds, the object departed toward the north and was lost from sight.
The bottom line is that, plants basically need 2 different wave lenghts for growth. Photosynthesis is needed to provide healthy growth of the stems and leaves. This in turn needs red-orange light To stimulate flowering and fruit production, the plant needs violet-blue light All that you, the grower, need to understand is that LED grow lights can be engineered to meet both of these needs. As mentioned before they produce a minimum amount of heat, which means you will not have install cooling systems. With some of the other lighting options a cooling system is a must, other wise there is always the chance of leaves withering.
I noticed that although the red light emitted from this thing was very bright to my eyes, it wasn’t casting shadows and did not reflect from the surrounding bushes or from the polished surface of my hood. I could see the surface of this thing seemed to be fluid- like, and composed of what appeared to be millions of tiny dots of light swirling around very fast and was very hard for my eyes to focus on it. The perimeter seemed to fuzz out at the edges, like an aura or halo.
Thermal management of LEDs is a science in its self, there are a multitude of methods with the best not using fans (convection) at all. When you include a fan in an LED grow light to manage heat issues it introduces a moving part Moving parts have a habit of breaking down long before your LEDs fade. However, if you must purchase a unit with fans in it, make sure the LED has a long warranty and the fans are rated for a lifetime that exceeds that of the LEDs.
