I'm Begining to think mh is way better than hps until the very end!

well true lacy, but mother nature only set the rules, we can tweak the mechanics of what she developed to our benifit. for example. mother nature dosnt grow pot in hydro setups does she? But we do, and we get unnatural yields from it. The red light definitely jolts the plant into a rapid flower mode. But may not offer the blues that the sun does give off all year long.

Blue light has a super short wavelenght, red light has the longest. Air acts as a light filter, filtering out the short wavelenghts and scattering them around while letting the longer reds get through. The reds and greens get through and you see them as the yellowish orangeish reddish sun all year long, but the same light composition is not reaching us all year long because in summertime the shorter lengths which are blue get scattered around the air and thats what makes the sky look blue. All the blue light is bouncing around in the air before coming down to us.

In fall the angle of the atmosphere, sun, and surface are in a different alignment making sunlight have to travel through more atmosphere to get to the ground the reds get through in all intensity, but the blues get bounced around so long in the air that they are not as vibrant in the fall. But if you look at the sun year round it will look that same yellowish reddish, and that because reds and yellow and oranges always get through. And at dawn and dusk, why is the horizon yellowish reddish? You guessed it!

I say all that only to explain the mechanics of sunlight, we can tweak those mechanics and the way plants react to those mechanics all we want. And it is proven that intense red hps light jolts plants into quick flowering.

If you want it at best possible mix of red and blue get the new ceramic hps bulbs they cost a tone but maximize the red and blue mixed spectrum with max intensity

Yes this is true BUT so does 12/12. Plants automatically stretch preflowering hwen this happens. I think the hps only adds to this even more so.

yep! What fletch said.

I can't get too technical wif it.....it makes it lose its appeal then.

YOu should go check out the tail end of the CMH thread. I don't think they are likely best for flowering with. They have a significantly decreased red spectrum, so you're adding blues at the expense of red.

Light is brighter maybe cost a few more $ but u get what u put in. Any comments?

i use both ,a 400 m.h for veg ,and then add a 600h.p.s when i flower ,so they get both spectrums of light ,seems to work well.

 

[Lacy]

I disagree. I think using either an MH and getting a more balanced bulb spectrum for each cycle or getting an hps with specific bulbs is a good way to go. There are more blues in the flowering stage than people assume. Get out a sun colour spectrum.

I think this is the ideal way to go..or grow.
When i can afford it I will do the same thing BUT I would use the MH for veg and the MH plus the hps for flowering.

Ive heard peeps say that flowering with more blues gives you better quality mj, but flowering with the reds gives you denser thicker buds. So i agree with old girl, bothe MH and HPS would prob offer the most premium ganja.

 

[ceestyle]

Yeah, i would agree with that (MH+HPS for flowering), but it really depends on what you want. If you're looking for g/watt, or g/kwh, I would go with HPS.
