Red And Blue Light.

I've noticed that the plants I have vegging under the hps seem crisper and to have sharper leaves whereas the ones I have beneath the metal-halide have rounder leaves. The ones under the blue also seem greener, but i'm almost sure that this is to do with the lights being on. I mean blue would show green off a little better than red.

Yet, there is definite difference between plants vegging under red and plants vegging under blue.

I wonder if there's going to be much difference in smoke quality, yield etc.
Originally we were going to switch bulbs as we have two blue lights and one red, alternate them every night cycle. But we've decided to keep them as is.

I might even market the product as jtr red and jtr blue. Can't wait to smoke the hash off this plant, anyone please give me some tips? If you can please answer in my resin thread.

Yeah you can see the difference in the texture of the plant. I have done the same thing. I really couldnt tell if either side was any better.

metal halide always makes plants look more natural because they are closer in spectrum to te sun. HPS however, has more lumens per watt

We've just started flowering and have decided to switch the red light to the middle. In the knowledge that the plants in the middle will now produce the best quality smoke. I wonder what is going to happen to the ones we started vegging under the red as they will now be flowering beneath the blue?

Another good thing is that over the next few days we'll be pulling out the males, giving the females a whole extra third (thinking positively) of space and likewise light. I'll add some pictures to my gallery, maybe delete all but the nicest of my last ones, a week into flowering.

Uses the Rollitup profile
Using MH light (warm, blue) versus Sodium light (cool, red) may make a small difference in flowering, but not to potency. Potency is genetic. The only difference may be in yield, due to Sodium causing more stretching during veg, but that will be small.

Sodium gives most lumens per watt.

no, mh is actually bad for flowering. you want to flower with a hps, and veg with a mh. or you can use a hps for the whole thing if you can only have one or the other

ok soo.. what happened with the experiment. Did the mixed spectrum produce better results?? I think I remember sumasshol mentioning it might be better, a year or so later, hmmmm.......VV

That was my first grow... even then I think I was fascinated with this amazing plant. I still want to know everything.

To answer your question, yes. And all the bud I grew on that op' was top notch.

When you say potency is genetic, this doesn't mean that we know the actual potency adaptability of a plant. Genes can adapt and evolve to match a given environment. Why couldn't a plant adapt to become more potent?
Saying that potency is genetic can be a very broad term.

a plant will not adapt potency without a different strain to breed with and create genetic variety.

so yes, all things in a grow being equal, the THC potency will max out at some point and will not raise without a breeding program.

I think you misunderstand me... or rather, are missing my point. If you get a plant that is very potent, take a clone and put it in an environment with less UV it will not get as potent. So what if we did the reverse, just push the plant to it's UV limit (which might not be the sun), what then?

Do you really think the potency has been maxed, with the limited amount of light spectrum and such we give our plants in an indoor grow? Sure, indoor strains must have adapted to the limited amount of light we give it but surely we can squeeze out a bit more.. or hopefully quite a bit more.

You could at it like this, which is probably shit but here goes: Think of your plant as a standard factory car. You get the engine and gearbox and all the things that make it work, we know we need fuel, water, oil(nutrients)etc etc to make it work normally. You could add Ethanol or Nos to it' fuel(nutrients) and get a whole lot more out of that. Then if you want you could add a turbo, gaining a few horsepower(potency), then add an intercooler and you have even more horsepower. The car might have worked perfectly as standard, but knowing what will improve the horsepower and adding it in the right order you have turned a 100HP car into a 200HP car. Might be a shyte analagy but its fun:peace:

I am beginning to think that the preponderance of information saying the we should use this to obtain that has been driven primarily by commercialized gro-ops that have an emphasis on speed and weight. of course the weed can't be shit...but.....so with greater lumens per watt, the HPS has been adapoted as the go to light. everything I am reading about (1) the natural circumstances of growing cannabis and (2) some basic properties of light and physics would strongly suggest that if we want to have more emphasis on the quality of the bud, we may want to rethink our "traditions".

The post of "seedless marijuana - the hoax" puts forward some very strong (and logical) arguments.

this is taken from a guide on a dutch site....

"With multi-bulb HID gardens, use one MH to each HPS lamp on a light balancer, and hang the lamps about one foot closer to the plant tops than usual. MH's favour blue light, and HPS's produce more orange-red light. By combining the two, the spectrum is more balanced, and you'll get a better return of well-formed buds."

Chuck a UVB lamp in there and bingo.. damn you would need quiet a setup to get a MH/HPS though, heat/space wise. I think thats where most growers problem lie, there's just not enough space and ventilation in most domestic houses to have such a large setup, well for me at least

yup...I totally agree with you...cost of electricity, room to grow, manage the heat....etc. etc. these all become factors in our assessment and evaluation of what will give us our heavenly smoke. BUT.....if you want to emphasize the naturally inherent properties of the weed, then those limitations may have to be re-prioritized? or we accept a compromise? or we develop a new strain?....now that's where this will get interesting....and there are hundreds and prolly even thousands of people trying to do this....so just to be clear....i do not expect that we are the only ones talking about this.....

All of this tells me that the right light for growing are the ones were you can easily mix spectrums of bulbs like, cfl's, t-5's and led's. Then you don't have the light moving and heat issues, Not to mention using less electricity for the same results. VV

good point VV....the shortfall in total lumens may be something, as it would seem that despite a debate over light temp (colour K), there does seem to be concensus that light intensity is a good thing across the board. natural sunlight (bright no clouds at noon so to speak) is commonly stated as 10,000 lumens per sq. ft. I need to read more on this too. :peace:

Some one posted what Jorge has to say about the t-5's today., in a thread about ho t-5's. You know I don't link. I am convinced the led's are going to be here in less than 6 months. I have looked at a few, they seem to be a 3R to 1B mix. 25 watts = 100watts of hid's. VV

yea....I expect that might be the case....i am looking into it myself, and working with some others on testing this ....LEDs and HPS together....
