I need to get this off my chest

most sources of light can be modeled as a collection of point sources(every point of reflection as well), so inverse square law still applies, though clearly this sum has a much more complicated positional dependence than simply inverse square, but still....had to say something.....last time I checked, no one is using lasers on their plants....

as for the topic .....
DUDE !!! let's be honest....everybody has the right to talk and give advices and reccommend all kinda shit. STUPID IS THE ONE THAT BELIEVES AND TRIES an idiotin idea as all mentioned above. what do you expect ? everybody to know everything ?

people will always talk stupid shit....unfortunately

My whole point of my posts were that people who put their flo's an inch away were called idiots and yet there was no distance given. It has been my limited experience that the closer the better without touching and no harm was ever done to the plant. Is an inch to close? Only because when things are rocking it would be possibly touching at the end of the day. Do we really need to know the actual light intensity at 12 versus 14" say? I don't think so. I've asked twice now with no answer. If it's not burning the plant what's the harm with having flo's close? And why would a person be an idiot having them so close? I guess it was the way it was put out there that I thought was wrong.

As I have said as recently as a couple of days ago.....there's really only one true way to become a good grower and it's called experience. And while gaining that experience you'll have failures and triumphs the most important thing is to learn from both. I've been around this site for almost 4 years and found out from just reading posts from different folks that a new member asking one simple question will get multiple responses more times than not with conflicting answers.
Which only leads to more confusion.
I often feel sympathy for the true noob who only come here to gain knowledge .
I'm pushing 60 yrs old and have been growing for about 40 yrs. I don't ever give growing advice on this site. I know what works for me . But what works for me may not work for you. There are plenty of people on this site worthy of listening to and learning from....your job is figuring out who they are.Short of that one can only blame themselves if they choose to listen to and impliment ideas they read on this site without doing their due diligence.
Just one old man's .02¢
I'll go put my soap box away now !

I've had them as close as an half inch from the plants .

And that's why they refer to it as a "Law" - it is intrisically more binding than the "law of man" - whatever the fuck that is.

I would say it's more like impossibly complicated. If your premis is even correct (I've never heard of this before - how would you even begin to calculate the amount your light source is spreading out?).

If you're saying what I think you're saying - you would need an almost infinite amount of measurements and calculations. Ain't nobody gonna do that!

On the other hand, I would be glad to be steered in the right direction. How does this "Many Points of Light" Inverse Square Law work? How can I use it? I've always wanted to know how to calculate my Light Hood in conjunction with The Inverse Square Law. How can I do this?

I agree totally and have been doing this since 14 which was 42 years ago lol. I don't offer advice but do let people know what I do and have failed at lol. I still think I'm a newb lol.

I usually keep the lights as close as possible
CFL's or floros i usually keep them an inch away (as far as there is some air circualtion betwen plant and bulb and not burning)
HPS i usually keep it around 10-12 inch because even if i have great air circualtion and cold temps thanks to my AC, if its to close it will dry out the canopy .
