hey hardon lighting question.......

The bulb is better in veg then bloom but i have seen it do a good job in bloom. Nothen like a hps though. About the previous thred . . no the sun doesn't change but the intensity does MH copies the cooler less intense spring sun, while the hps copies the more intense fall sun.

You are half correct :)

I appreciate hearing your input about the HPS bulb in flower...

Let me rearrange into correct order what you said about the light from the sun.

MH copies the cooler MORE INTENSE spring sun :)
HPS copies the hotter LESS INTENSE fall sun. :)


I say this because remember....

Red waves are moving AWAY from any point in object.
Blue waves are moving TOWARDS any point in object.

Thus the spring and MH provide cooler yet more direct sun waves :)

We use terms cooler and hotter not to talk about specific heat but the Kelvin temps and intensity.

MH as spring has a much higher Kelvin than a fall HPS....but that translates to intensity. We say cool because it brings out the 'cooler' colors like blue and green, while HPS has a lower Kelvin, thus less intensity, while bringing out the 'warmer' colors such as red and orange.

Thanks for the follow up :)

I'm warning you don't read this if your high........ like me....

Me just trying to be helpful.... :)

Some of this you can skim over.
