220w CFL 4'x4' floor plan, superior to 400w HPS

i automatically gain at least 6 inches of peno from the fact that my light sits on top of the plants. this is fact. my setup must blow any hps away for lumens unless the scientists who maade this are wrong.

if i understand that chart correctly then a 150w hps thats rated at 16,000 lumens is worth 16,000 lumens within 1' of the plants, 3/4 that amount 2 ' away 1/2 count 3' away and so on and so on...correct. well im not sure where you can find 16,000 lumen cfls at 150w or less because my plants will get within 6-9" of the bulb with my cool tube fan turned off and will wrap around the glass when the fan is on.....:bigjoint:
 
my flouros are 54 watts 5000 lumens of higher par than hps. the lumen output is still more than enough. you saw my pics 12 hours ago. here they are now. and yes the lumen chart is exponential. a couple inches = huge gains in lumens. gimme some props here i'm no pro but these outta yield huge. the nicest lowrider i've ever seen at this age. 18 days from seed today. i'm just proud and happy so don't mind if i brag abit. just happy not arrogant. what do you think? they are nice. i really don't know what to expect.

:bigjoint: dont get me wrong brother your kids look nice and healthy..very well taken care of and are loving there enviroment....they love the flouros in veg but in flower watt for watt hps outperforms every other lighting available on the free market..period. if you are growing for light personel use flouros can and are sufficient enough to take you through a grow and give a decent yeild and quality herb...not disputing that one bit what so ever...if you are growing for profit nothing compares to hps for flowering...:bigjoint:
 
we will see. i won't make up stories that ive grown this strain under these lights but these lights are perfectly able to produce buds just as dense as hps. if they were a tall plant i would use hps. but with these the light doesn't need to penetrate the canopy as deep. flouros are as good for flowering as hps on short plants. for taller i'll admit i would use hps. these plants will finish prob 12 inches tall only so this setup keeps them very equal. but def for taller strains hps could yield more. but it depends on the experience of the grower to

Technically, if you could direct all photons into one square foot, yes, it'd be 16,000 lumens across that one sq ft.

A distance of 2 feet it's 1/4(2 ^ 2), 3 feet is 1/9th(3 ^ 2):

intensity = lumens / distance(feet) ^ 2

^ means 'to the power of'
 
So I made some more renderings to do comparisons of bulbs. This is the only practical way, really, as it involves 100 26w CFLs! :mrgreen:

The renderings are self-explanatory -I hope. That cylinder can be thought of as similar to a full-grown(hefty, like Will Sasso before he lost all the weight) man. :bigjoint:

Any questions, fire-away!

First one is 100 26w(1600 lm) 6500k CFLs (160,000 lumens). Or you could think of it as a canopy 12.5'x9' at 650 watts times 4.

Second is 160,000 lumen HPS.

Third is 50,000 lumen HPS

They're all the same angle and distance.

so basicaly you need 2600 watts of cfl to match the lumens of 1000w of hps....

and if 1000w is putting off 254sqf of light coverage then 2000w would equal 504sqf...still superior to the 450sqf of 2600w....or am i reading that completly wrong....
 
heres what 160,000 lumens of hps does for me at 2 weeks veg from clone...pretty shitty right:bigjoint:

Well, CFLs output ~5.7 W/sq ft. The 1000w HPS outputs ~3.9 W/sq ft. And the 400W HPS does ~3.5 W/sq ft.

I was thinking of doing 100 CFLs over 25'x25' with ~4.16 W/sq ft.

Those are all theoretical maximums.
 
i don't know that much detail about light but i can say your 160000 lumen hps looks like its throwing at lest 75% of its light onto the walls. thats how all hps grows go

:roll::roll::roll: do you just pull these numbers outta your ass....your just being rediculous now saying that there isnt light efficiency in this room....

its like banging your head on the wall m8 they will not listen to proof/tested methods they think that paper predictions grow plants better. what tree is saying that every cannabis grow book ever wrote is wrong about what light is more efficient. i have shown proof that a hps watt for watt will yeild more bud than a CFL with pic's to prove it, to grow the same amount as a 1000watt hps you would need 1500watts of CFL lights. HPS are 2x more efficient at making light than CFL's fact!
 
I would never use CFL in a room that big, I'd have 4 ft plants with lots of hps... then again I'd shit my pants before I went that big. Whats the biggest you can grow in your bedroom and still keep odor under control? I think what we're getting at is you don't need a 400w hps if you use a few cfls and capture the light with plants effectively. You can grow on a much smaller scale, but way more efficiently, using his original 220w design.
 
hell yah. and i still stick with my statement that hps throws most of its light around the room and not onto the plants. not saying that that room isn't done right. it looks like a nice grow room. And in a room that size i might use hps because they are cheap to buy. But t5 is still capable of flowering the same amount. throwing out numbers? you claimed 160000 lumens. and sorry not 75 % of the light is missing the plants. its more like 80%. just look. just because you have white reflective material up it does not reflect but a fraction of the light back onto the plants. most is absorbed. still a nice room. how many watts does it take to cool? a room that size at least a couple hundred watts if not more. that counts as power wasted. cfls might not form huge buds the size of hps but they take less power to do it. they are perfectly capable of 1 gram a watt. thats good by any standard

:weed:heres the facts brother and im not trying to be rude in anyway, but your wrong ..plain and simple..you speak from assumption and ignorance. i speak from fact and experience. you can go on and on about what you "THINK" and I will continue with what I know..like I said..ive used cfls, leds, and hps. I will continue to use hps for the plain and simple FACT that watt for watt, dollar for dollar (even with the colling equip) hps outperforms everytime...happy growing......

oh..and ive only got about 20w in cooling.......so you can through that argument out the window

and cmon now...the quote" cfls might not form huge buds the size of hps but they take less power to do it" that makes absolutley no sense whatsoever..your just grasping at straws now....or "hps throws most of its light around the room and not onto the plants" one light bulb does not "throw" light more than another..all light travels in any direction unless its reflected to a specific area. hps light waves dont back flip and zig zag all over the place while clf light goes straight to any plant that is in its general vicinity...think before you make statements like that
 
not really fact. i have both setups if you count t5ho. i have both separately. they both produce the same amount of grams per watt. this is on short plants. with taller plants you will lose yield with flouros. but honestly i see on short plants that they grow the same weight every system watt considered. just the 450 watts of hps i have take alot of fans to cool. i like them both but with the short plants it doesn't make a difference. i am also saying that it does not outyield hps but is basically the same on the short plants i grow. My arguement is a little off topic. I don't believe that regular cfls will outperform hps but highend t5s are about the same i feel from experience. and no i havn't grown any massive plants under them because i know what they were designed for.

yes fact......hps out performs time after time.period

t5s by the way were designed for under cab lighting in kitchens and bathrooms...

air exchange is a key ingredient to a successful grow room. The ideal air exchange rate will vary at different times of the year and from room to room depending on things like grow room height, etc. a minumum of about 30 air changes per hour is recommended this works out good with hids because the more you exchange the air the better your plants will be. as i have said to grow the same amount as a 1000w hps you will need 1500w of CFL you will use much less power than 500w to cool a 1000w HPS a 6" fan uses less than 100w put that fan and HPS in a cool tube and get the light to with in 12" of the plant canopy work out how much light is beeing put down on the plants then.
