Yea man don't try to tame the sun with numbers and figures
You will only end getting burned..
Heaven is actually located inside the sun and the powerful light emmited is actually love.. and hell is on the the surface, thus where you get cast if your naughty lol
Fuk im stoned and talking shiiiiit

Correct
Also, it has more to do with spectrum than intensity, when comparing sunlight to artificial

Sure the sun is brighter AT THE SUN, but what you copied and pasted but dont understand is that it had to travel all the way to earth, and go through the atmosphere.
Just for your own refrence, put on a welding helmet and go look at the sun, then the bulb. There will be no doubt in your mind then.
Here is a link

If I get around to it I will scan a page out of the indoor growers bible

I know that i can stick a magnifying glass under my 400w hps(trying to solar puff indoors) and nothing happening cant start a fire. I go outside and not only can i not look at the bowl but it lights instantly. I can feel the sun on my arms much more than my hps, i really dont see how you can compare the 2

You are mistaking radiant heat with lux. Here is an example. If the tempature in your grow room is 70 degrees, why will the plant burn if it is too close to the light?
(Major Toke)
" Essentially there are two aspects to the thermal environment that you need to be aware of:
1. The AIR temperature
2. The RADIANT temperature
Although obviously related, these are 2 distinctly separate phenomena and your plants have different tolerances for each.
1. Air temperature
Your standard mercury/alcohol-bulb or digital thermometer is designed to measure the temperature of the air (But not radiant heat). This is what is being referred to in the usual growers 'rules of thumb' such as maintaining your grow above 16degC and below 30degC.
Most thermometers are only designed to measure air temperature growers often mistakenly place their thermometer in direct light; radiant energy will warm your thermometer and give a higher than actual reading.
2. Radiant temperature
Radiant temperature is the result of heat transfer bewteen objects at different temperatures without whats inbetween i.e. the air, being effected. In our case the plants are naturally at a lower temperature that the light and reflector so heat is transferred to the plants foliage from the light/refecltor through radiation. This causes the leaves to heat up. The plants can withstand much higher radiant temperatures (around 40-50degC) than they can air temperatures but if this is too high the plants can 'burn'.
The plants can withstand much higher radiant temperatures than they can air temperatures, but if this is too high the plants can burn.
'The hand test': Place your hand in a comfortable position for some time at the tips of your plants should be. If your hand feels hot, then the lights are too close, the radiant energy is too intense, and light burn may result. Do this test and raise your HID lights/reflectors periodically to keep light burn to a minimum. "
Another way to see the diffrence is to put a thermometer in a bottle of water and hang it at the top of the plant canopy. You will see it warms up hotter than the room tempature.
You could also compare a CFL to an incedescent light bulb. A CFL puts out more light, but the incadecent puts out more heat and yet it is dimmer.
If your sister has an easy bake oven look at the heat source, its a 100w light bulb, thats right enough to bake a cupcake but a 23w cfl puts out the same or more lumens (in the right spectrum) using 1/4 the power with no heat.

There's no need to bring in FDD...he'll say the same thing...the sun is better...but lights are better for controlled enviroments since you don't have cloudy days in a grow room. No matter where I look I can't find any info to back up that other guy that says lights are better then the sun, but rather the fact that the lights are controlled giving you more possible daylight.
On the surface of the Earth, the average solar illumination varies between 32,000 and 100,000 lumens per square meter, or lux.
Facts are facts...grow a plant outside and 1 inside, and see what turns out better...I bet the outside plant will be bigger and yield MORE.

The argument is that lights are brighter then the sun...which we all know is absured.

Brighter than the sun where? At the sun or on Earth?
Yes at the sun, in space 92,935,700 miles away, it is brighter, but not on Earth. A 1000w Super HPS is 150,000 lumens at 1 foot. 15x brighter than the sun hits the Earth of the Equaitor on June 23ed.
So Prove it. Give me a link that supports your 1,000,000 lumen per square foot claim.

Ok whatever...I didn't mean 1,000,000 at the surface, but I did clear up what it does produce at surface area, PLUS there are vital things that the sun produces that lights don't. I think in all fairness it's safe to say that the sun will ALWAYS do a better job at growing then any man made light could do.

Yup
Once again its more about spectrum....or more like its more about a lack of spectrum in lights

Tottally absurd! Light is just radiation in a narrow part of the spectrum. It travels like an arrow, just because HIDs are uber bright faced at the plants doesn't make them stronger than the sun. On earth (in the daytime) we don't see much darkness--that's because there is so much stuff all around us for the sun's lightbeams to bounce off of. So, almost any direction you turn your head, lightbeams will hit your eye. The sunlight even bounces off air molecules, and that's why the sky is light instead of dark.
"I put buckets outside to collect sunlight then pour it on my plants
Its as good as having your plants outside all day"
TITTIES!

Against 1? Lets see I have quoted refrences TO INCLUDE Jeorge Cervaties. It's not how many people vote, it is not a democery, it is either true or it is not. So how many people agree is irrelevent, it is who agrees with you that matters.
Again Prove me wrong. Site something besides a made up # like 1,000,000 lumens

OMG raed back a bit, i already said 1,000,000 was the wrong #...jez...stop smoking that good weed dude.
I was trying to make the thread a happy place but you keep coming in and bringin it down again.
As I stated earlier...they said that light MAY be better then the sun ONLY for control factors, like bad weather days...NOTHING on the fact that lights are better, at all level's of growing, the outdoors is the most desireable place to grow. Lights lack ALOT of vital things that the sun produces to help phtosynthesis...and that's a science fact.
