Now if you look at the spectrum of growing its a smooth arc. NOT (freq's or angstroms )
IF leds worked it would be all over the internet and in every industral user would jump on them faster than a duck on a june bug.
O WELL back to using 30 year old florsents 4 ft bulbs and a 30 year old Mh ballast and a new bulbs.
O lord I see the light, zaaaaap , darn its a bug zapper.
Now think if LED did work effeciently industy would use them in a heart beat. After all its only a few Billion dollars saved each year.
Do pot grower know something industry does not know.
Bottom line my fairy godmusther is a whore and charges for her favors. imp:
The reason why you donā??t get a red from what is called a white LED is that there is no red light in the spectrum (hence your filter cannot filter it out as it isnā??t there to begin with). Its really a blue LED with yellow phosphor (thatā??s what I've learnt). Interesting experiment though! I donā??t see how that could affect the chances of LED plant lighting succeeding? LEDs usually donā??t emit a wide spectrum because of the way they make light. That is an advantage in plant lighting, as plants only use certain bandwidth of light energy, so what you said is actually an advantage for plant lighting and is not a problem at all really.
