hmmm... let me smoke a little and let that set in... i think your statement about plants being genetically programmed or whatever to only be able to use 10000 lumens because of millions and millions of evolution just made all your "facts" completely NOT facts and your own theroy.. and you still are avoiding the question... WHAT HAVE YOU YIELDED AND UNDER WHAT KIND OF LIGHTS?!?!?!

what causes the bleaching exatcly?? is it due to heat build up?? or is it like us getting sunburned or getting sun poisoning sorta of?

like i said its all theoretical fact. i.e if you had a graph where x was light and light absorbtion and y were the other "links" as y increased so would x, respectively. if it could be a continous line that never ends, you would see where it would surpass 10000 lumens.

ok kaptain BS.. first what the hell is theoretical fact?? is that your way of making what you think sound not as stupid as it really is?? that somehow it makes it sound smarter?? dont get me wrong.. the idea is a good one.. at least.. IN THEROY.. just state it as opinion and theroy.. not fact... this is my first real post.. ive been a long time reader on this site.. just never got into posting or anything... and it seems there are a lot of people on here that use what you seem to call "theoretical facts" that in no way really help anyone out... just PLEASE help seperate fact from fiction and make sure to state your THEORIES as that and NOT make it sound like fact... also... why your creditbility is even further going down the drain because you seem to just be avoiding what i asked like 3 times now..

ok- your logic would make sense with a machine (your car analogy). but think about it in terms of a living thing- a human cant have ever increasing strength- we cant just beef up every organ and system within our bodies within a short amount time to point where we could pick and toss multi ton objects. so i guess my thought is that there is a limit on the amount of light that a plant can utilize- after all, if you a plant could utilize near inifinite amounts of light- then there could be near plants near an infinitely large size, that doesn't soud right to me

as a professional pothead i am always looking for ways to not sound like a professional pothead. i call them stonerisms. look at my signature.
and as far as yields and lights
ive been using sunleaves satellite lights. before you give me shit on using flors, the satellites are stronger than standard t-5s and penetrate very well. also ive been experimenting with different arangments and set ups so yields vary.
5 crops (10plants per)
soil grown
1rst harvest 2 lights 6 oz dried
2nd harvest 2 lights 4 oz dried (2 males)
3rd harvest 3 lights 7.5 oz dried
4th harvest 3 lights 9 oz dried
5th harvest 4 lights 1.1 lb dried
no i dont have pics. just foggy memories of them. believe me or not.

REZ has the right idea.. and as i said.. in theroy its a good idea.. but its as far from fact as you can get... if what you said is true kaptain we'd have trees growing near the atmosphere... and yea.. ill believe your grows... because you are obviously not a good grower.. those lights use 420ws (go to wormsway.com.. thats where google sent me)... that means on your last grow you used 1680ws... that means you should have got at leasta couple pounds dried.. at a gr/w thats 3.75 pounds.. hell id even give you a half gr/w... and you still arent even there.. thats a terrible grow... im glad to see your yields increasing.. but if you cant use your lights correctly why keep buying more?? seems you should spend time using what you have before you buy more... damn... your pretty much wasting your time it seems...

as i said ive been trying different set ups. i am getting all dialed in now. hopefully ill get closer to the gram per watt that i want. i actually plan on getting more than that. another 3 or 4 lights and i should get at least4 pounds or more a harvest! ill post pictures of that if i do. my plants will use all the light i give them. they are using it all now!

that would work if the slope of the line connecting the points on your graph was linear. if i ran some experiments it would probably be more like a polynomial/exponential/log type function- which means it would eventually hit a limit

that means you would be wasting light

you say that like your gonna be proud of that.. 4 pounds off of 8-420w lights?? talk about a waste of time money and light... LOL wow hold on while i catch my breath... ok... so lets break it down... that would be a total of 3360 watts of light... which means you would just barely be hitting the half gram per watt mark.. WHICH IS STILL A TOTAL WASTE.. why not spend the money on HPS where the real yield is?? didnt you post that anyways?? wanting advice on HPS and how many to get?? i dont get it i guess.. this has went way off topic.. but... it seems like you are off in some little world and know nothing about actuall growing...

alright- lets all chill out- take a hit and relax. leave out the emotions - lets roll on logic for a while

im trying to.. but as i said in the beginning i wanted to start a thread with some intelligence and not a bunch of stupid misleading information.. but.. your right.. we can keep it civil.. so back to the topic at hand.. what size of a plant do you need to optimize light absorbtion and use? does it matter how big the plant is?? i mean a 2 foot tall plant will use more light than 1 foot plant (i would think) so what is the optimum plant size for usage if all 10000 lumens were available to it?

i know.. i guess this whole thread was really started with a buncha of hypetheticals anyways... i mean.. i know there is a point where light because excesive.. i just thought it was at least a cool idea and would spark some debate.. which i think is more or less what kap was trying to do.. i just didnt want his ideas to be mistaken as actuallities.. the idea that it is possible to grow a plant with truley no limits is an amazing thought.. i mean if it were possible to grow a 4 foot tall plant using 4000ws of light and have that plant use all the light, not only would that be absolutley amazing, but imagine the potency... i wasnt looking for a real answer.... i think we all knew the answer... just some good debate... and would it ever be possible to do?? i think you would have to flood the plants with lights and breed and daughter plants through seeds not clones and slowly change the genetic structure to make the plant capable of using that amount of light... i mean since i think the limits of light absorbancy are based pretty much on millions of years of evolution its HIGHLY unlikely that anyone of us would live long enough to actually see if that sorta of experiment would work... but it would be a very interesting experimentt to do if we could live a few hundred years...

Genetics limit everything man. Just like you can't grow a 12 foot person by feeding them twice the amount of food a normal baby gets. Even making sure that person had enough water and oxygen, they are still limited by genetics. Plants are no different.
There is a reason that not a single greenhouse in the world grows ANY plants with enormous amounts of light. It simply doesn't work.

The Sun puts out between 72,000 to 100,000 lumens. But the Sun is free. I believe my 1,000 HPS was plenty. Plus the use of mylar on sides & floor.

What would you consider to be an enormous amount of lights? How many watts would you say is too much for a plant?

Get away from thinking light per plant - try and think sq ft wise. One person might have one large plant or 16 smaller ones in a SoG set-up to get the same yield.
Years of experimenting by thousands and thousands of growers have shown that the most efficient set-up is close to these.
Anything over these suggestions is too much in my opinion and a MUCH better use of your lights instead of piling more lights on one grow and chasing diminishing returns, you should just start another grow using that next light instead.
- Primary light (no natural light) coverages for the different grow light wattages are as follows.
- 100 watt lights: 1.5FT x 1.5FT growing area
- 150/175 watt lights: 2FT x 2FT growing area
- 250 watt lights: 3FT x 3FT growing area
- 400 watt lights: 5FT x 5FT growing area
- 600 watt lights: 6FT x 6FT growing area
- 1000 watt lights: 8FT x 8FT growing area
