UPDATED. I've been using these lights for a few months now and I am a firm believer. The key is figuring out the proper height. Raise them higher approx. 2 to 3 feet if you want the plant to stretch a bit or 12 to 16 nches if you want the plant to get bushier. light orbs video Also this light will cover 2 sq feet. Dont try to get more out of it or your plants will suffer. Right now I'm using a 4sq foot grow tent and I am using 2 of these with 2 blackstar 240 watt led's and my hot pepper plants are producing like crazy.
while driving from bay city, mi to caro, mi traveling east on gilford rd just east of reese rd and near s. vanburen rd. i witnessed a light to the southeast of me that was blue then green then yellow then red it cycled like that 3 times and when i got directly beside it to i saw whatever it was flash bright blue and orange and yellow sparks trailed the object the blue and the spark trail hung in the air for a few seconds then faded away. it moved very fast and was gone in an instant
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.
His brother did call me and I found out that he and his friend had gotten their flat tire right on the highway near my road. They had pulled off onto my road to change their flat tire. I did recalled seeing a car parked as I turned onto my road that Sunday night on our way home from the movie theater. My daughter and I had seen this red light moving away from our end of the neighborhood while they had seen it coming towards them at the opposite end of the row of houses near the highway. Thats what my daughter and I had seen too.
C) Higher end - These are more often the full spectrum models that cover approximately 420 to 750 nanometres, the PAR range. They include expensive white LEDs and in photos you will see some LEDs look like they are ‘dead’ – not true these are emitting in the far-red portion of the spectrum which is 710 to 850 nanometres, dimly visible to some peoples eyes. Look for high end components such as brand name LEDs from Epistar, Bridgelux or Cree. Thermal engineering is a key to design with the best being fan-less. LED grow lights with these features offer excellent results with thick and juicy buds.
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.
