Yet for some reason in every one of these LED threads it is always someone with a recent join date and a low post count who is claiming LEDs are the shit. And oddly enough their supporters make their first post in their defense from proven methods of experienced growers all the while never offer a shred of pictorial evedence. I have read multiple threads like this one that always end the same. The LED saleman opens a new account under a new name and starts a new thread claiming LEDs are the best thing since the wheel. See ya in the next thread sucker
I never made claims to LED superiority in any fashion other than PAR light per watt. And even light per watt(up to 130-160 lm/W). Which is a *fact*. It only stands to reason at equivalent wattage LEDS would out-perform HID(HPS/MH specifically) for growing plants. MH is technically superior to HPS as well. Check out Hortilux lights, they have a dual HPS/MH bulb. I've seen some very impressive grows with them. Beats solo-HPS easily.
LPS, or low pressure sodium emits 200 lm/W('best light EVAR' in web-speak). They also emit their light at around 589-590 nm. Pretty much useless for plants.
NASA has proven (red & blue) LEDs work to grow plants, *fact*.
LEDs will grow marijuana, *fact*.
What is it with people and *facts*?
Let me take a swing at it:
Most people(at least the LOUD ones) here have a complete lack of understanding about the spectrum and intensities of light required for optimal plant growth and photosynthesis. They go around stating baseless and fallacious information. Making comparisons where they ought not.
You seem to be in that category.
Plant growth is a SCIENCE. Not Voodoo.
You disclaiming my statements based on my post count only demonstrates your complete foolishness and lack of understanding.
