you have no idea what I have grown indoors. wow the arrogance around here.
I have never said anything to assume any of your expertise but since you did, I am sure I have way more experience and pounds under my belt than you do.
What is outdated tech to you? LED's? or just the purple thing. Here is a statement from a quality LED manufacture who makes nice lights about the white light. They use white LED's and here is what they say.
While white LEDs can provide good response and growing power in very young/immature plants, the most efficient, powerful way to fully grow plants is to tailor the spectral output of an LED grow light to the Absorption spectrum by use of narrow banded LEDs in a perfected balance. White LEDs by nature are and inefficient and wasteful when used as the primary source of light in an LED grow light. This inefficiency goes against the very core principle of the concept of LED grow lights which is producing 100% usable light by way of a perfected spectral output as it pertains to the rate of spectral absorption by green chlorophyll. Not only has scientific research shown this, but actual results of growers worldwide have proven this time and again. Not only this, but due to the very nature of how “white” LEDs are actually a phosphor coated blue LED, they will never reach the same intensity level as a quality narrow banded LED. When you filter light, you lessen it’s intensity. Since intensity spectral output are what actually grow plants, these are not only the most important factors in an LED grow light’s power, they’re the only factors with regards to growing power.
wont let me post a link for the reference because I have only been a member for one day but check with the guys at any pro led shop and they will tell you the same. got this info from folks at platinum LED. i will link the scientific document when i find it tomorrow and will let me.
