I have pro colors before they went out of production and they are NOT pink,.... far from it actually they are quite redder than the other red bulbs..

Its not the spectrum just the quality of the LED i was trying to show you the difference in the so called GROW LED vs a much higher quality LED color is irrelevant because the LED manufacturers produce them in plenty of colors those just happen to be the cool white variety.

Great looking buds the nute burn wont hurt that much i would extend the flowering period maybe even clip and let the secondary growth fill in.

You are correct sir! if anyone wants to see true LED lights http://search.digikey.com/us/en/cat/optoelectronics/leds-high-brightness-power-modules/525140?k=Cree LMR4&vendor=90 http://orphek.com/led/orphek-products/pr-156/ http://www.youtube.com/watch?v=uzPlTIPpOdU&feature=fvwrel...

You must also remember that 3w led's are less efficient than 1W led... also most 3W led are 3x 1w on the same board... which is how they "sell" it ! Then to make matters worse most led manufacturers run their led's @ 750mw vs the 1k/mw in order to be more efficient. pbfft... i would love to...

You can use t8 there are bulbs available for t8 that you cant get for t5... however t5 are a better coice IMHO and conversion kits are just ballasts and endcaps... check my journal i have some endcap links and for ballasts there are so many choices. I would get the Fulham workhorse ballast very...

Great to see such a good thread it hard to keep people on "task" so to speak once theres over 150 pages.. theres always going to be those trying to push an agenda rather than use facts to prove points..

THOSE ARE THE "GROW" BULBS LOL....you know the ones that these hydroponics dealers sell you!! no one listens to me...

Computing Dictionary dirty power definition Electrical mains voltage that is unfriendly to the delicate innards of computers. Spikes, drop-outs, average voltage significantly higher or lower than nominal, or just plain noise can all causeproblems of varying subtlety and severity (these are...

care to wager on that?

Not to shut you down but chlorophyl isnt MADE at those specrums... its "sensitive" and produces more energy at that spectra. the trich is to find a bulb that has a very narrow output with a specific spectra... these specific spectra are easier to control like the super actinics are 420nm...

Actually no... BILLIONS OF YEARS! Plants are damaged by MOST of the suns light. white "yellow" light is essentially useless to plants.. good for us.. See the sun ACTUALLY emits UV XRAY far infra red radio waves etc also known as solar radiation... Most of the suns radiation is harmful to ALL...

:cuss:I would stay AWAY form anything that links together... ESPECIALLY with a ballast! why you may ask? well simple answer... DIRTY POWER! (line noise) & Surge!!!! one ballast faulting can take out another, cheap ballasts are sensitive to line noise and small surges, remember ladies and gents...

Some more pics of my pioneering. please enjoy.. I have a petition going to get a T5 Category please post and sub and rep to help get this technique its own category and attention that it deserves.

T5 Love :0 please enjoy and check out my thread in my sig.

Great work Undercover. Glad to see my hard work paying off and my knowledge and skill rubbing off...

187 now :)

Nah just late night and wrapping a gazillion presents... you cant criticize something than use that very thing as proof of point. second some graphs are measured in luminious flux, others are measured in intensity... you can t just measure the charts peaks and say "well its 25% percent 410nm...

you an me both.

You clearly dont understand how to measure energy. Light like all waveforms comprises of ENERGY not Color. the color is the reaction to the matter that the photons interact with, then are reflected BACK to your eye. You CANNOT pull numbers out of your ass to prove a point. Luminous energy...
