google+searching on leds=good for something
On averaging some of the information on Leds out there I have this:
Before it sprouts warmth and infra red light help germination.
After sprouting you may use only blue light 420nm+ to keep the stems very short for awhile.
NASA found for lettuce 2 parts red led at specific color and 1 par blue led gave the most efficient growth per watt given the range of LED colors they tested. More colors are out now and thousands of led color combinations and ratios are being tested simultaneously around the world.
This mass group effort is reported at forums such as the one at greenpinelane.com
Too much blue and your peppers will not flower.
Too much red and they will be leggy.
The ratio of red and blue light changes through our seasons.
This research will continue for some time becaue the hype around the blue and red only needed is correlated to one of the two major graphs for plant activity. The first is how much chlorophyll gets made and this does peak in red and blue.
Because people want to make a fast buck you see sites exclaiming that red and blue is all that is used. While they are used mainly to make a main ingredient they are not the triggers for overall activity and stages.
As time progresses we will have very specific light spectrum available for various stages of development.
Currently the 45w red and blue panel will grow your pepper plants well however if it will make peppers is another question.
I have been researching nutrients and led lights extensively in order to well serve customers on my nutrient site with very well backed and very well understood products. It will not open until I am asked questions which everybody is happy with the answer
It is difficult and expensive to research- from lights to nutrients there is a lot of junk out there it only takes a few of the right things to get great results.
