Chill out guys were all friends here

One thing I will say is that everyone on here are like scientists compared to me lol

Keep the peace everyone we all want our plants to grow the same way, lets all help each other not fight :-):-):-):-):-):-):-)

the data that you are trying to quote is working under low light level conditions. similar to what you will find underneath a full canopy ... hence "shade response studies". For goodness sakes they are talking about 100 to 200 umoles of total light. absolutely irrelevant for production light systems.

from the paper that you cited:
"The white light sources emitted 1000 and 500 footcandles (approximately 200 and 100 lmol m2 s1, respectively)"

So where's YOUR study showing that at higher intensities green DOESN'T suppress growth like at low intensities? You didn't cite ANYTHING yet.

Chill guys we should all be helping everyone, all of us can learn new things off eachother :-):-):-)

Good attitude, unlike whatshisname. Seems to think that suggesting that green light could have negative effects is highly offensive. Maybe he's the President of the Green Anti defamation League.

some interesting stuff in the Old Threads, not just the first 5 or 6 pages go back to page 234 or older like 876etc, some amazing info' its only a few years old aswell so still highly relevant, some wacko stuff too but very entertaining......wlecome & Enjoy

its called mcree curve, sunlight and the dozens of grows being posted on RIU.
Even good old hps which has a huge spike in yellow-green region bunks your theory.

and then finally the performance of my neosol from illumitex sucks compared to a warm white cob as the neosol has very poor canopy penetration because of the lack of light from 500-600nm.

You can take what you will from what you've seen. I can take what I will from scientific articles. I can express my opinion and if you disagree that's your business. You saying bullshit isn't likely to bring me around to your viewpoint. It's actually a lot more likely to cause me to write you off as a common annoyance. I posted in other threads about the same thing, and whenever the author of those threads asked me not to discuss it anymore I immediately agreed and left their threads. That happened exactly once, and I sure haven't missed that person's threads in the slightest.

I hate to see bad info being posted that will mislead less experienced growers.

yes teacher (snickers in the background while getting a spitball ready)
sorry joking aside.

the problem is that the belief that green light inhibits plant growth under production light levels is similar to saying that the earth is flat after the globe was already circumnavigated.

if you had said I want to explore the best ratio of green light to red and blue wavelengths under X light levels, I can understand that and if you concluded the right balance is different I can accept that as a difference of opinion.

But your insistence that green light inhibits plant growth under production light levels is absurd.

Ya gotta admit, its fun watching the digression from the question, quite educational some times.
you decided what your going for?
easyest and cheapest till you get the hang would be cfl's then after a couple of weeks saving get a better bulb, just keep on like that till you got what YOU have figured to fill your needs, its all part of the learning curve- sometimes its vertical but fun.
i had normal house bulbs for my first grow in the 70's....still got stoned after the harvest.
Enjoy the debate
and you two Bob & Purple..... play nice
