Photosynthetically active radiation http://en.wikipedia.org/wiki/Photosynthetically_active_radiationI've got one for ya: What is PAR?
It was mentioned by homebrewer: "Lumens are for humans, plants only care about PAR."

Thanks! Although now all the math and new & confusing units are stunning me, i think i can understand the fact that a cool white light is better for growing than a warm white light even with both outputting 1000 lumens?Photosynthetically active radiation http://en.wikipedia.org/wiki/Photosynthetically_active_radiation

honestly i just googled your intital question and found the answer lol
I was gonna make a remark similar to this, and then went to page two instead of the last page.
I, a newbie to growing, but I'm a senior with a biochem major and I always learned that genotype was a plants full genetic makeup. Phenotype were the physical traits that you can actually see.
For example, a plant can have genes for indica and sativa. So its genotype is hybrid, but its phenotype could turn out as indica, sativa, or hybrid, depending on which genetic traits are physically apparent (also known as the phenotype).
I guess the definition is that way (genetics+variable+environment) BC those can all affect the physical look, but that's getting more into nature vs. nurture. Its like if you have brown eyes, but you have the recessive gene for blue eyes-- your genotype has both genes, the phenotype is the gene whose characteristics are visible, in this case the dominant gene for brown eyes would be the phenotype.
You ain't being prang ,there are shitcunts out thre who live of our hard work n love ov da Herb! I've had some girls ripped up and they still had at Vleast a month to go.i know it was,nt da land owner cos the dirty mongrels dropped a used syringe(says it all)any way I FEEL for you cuz I am a English Roma so a gypsy curse on the mongrel.one love SMUDGA
Cool,a thread to educate the cops...i took me a long time to learn most of that stuff
