LED grow lights... input please.

[sheist]

that time lapse clip was from the nuturelite website.. however it can't necesarily be compared to the growth to a mary jane.

what 2 colors make purple....red and blue primarys,, they just mixed the lights.... of the 2 colors..it would be interesting to see the spectrum of that light

the way i see it, thats wrong.. u can't make the spectrum because you mix two colors.. purple has a specific spectrum, look at the scale.. THATs why the plant is growing so well.. there is another contingency on the scale that ppl neglect (even I had, before I saw it)... in addition to the blue, u should also add the purple spectrum LED to it, to get that extra push in there, u can see how well its performing on that plant without the blue..

u still can add green soo the plant looks good..

adding green is a waste of money.. its not as much of a potency factor as the others..

you can project the same amout of light equivant to a 1000 hps setup on a 3 by 3 or 4 by 4

with LEDs? no, u can't.. LEDs are based on spectral intensity, not illumination..

as for sulfur lamps.. how much heat output is given off??
