Dude, if you grow popcorn buds with your 600s then you need to learn to grow weed.

The Biggest bud I have ever seen in my life was grown with 5 x 600w lights. Not a single 1000w in the grow room...Health Robinson is a God of growing..

This is a 1 pound bud grown by a member known around here as Health Robinson. He grew it in the "critical mass tree project" with 5 x 600w lights.

So are you still going to try and tell me 600w lights cant grow big fat buds? I think you just had a bad experience, it doesnt mean that a single 1000w is better then 2 x 600w because of a bad experience your or someone you know had.

these buds are grown under 1000w HPS

i like heath dont get me wrong but it comes no ware near what crusty used to pull using tree grows and 1000w lamps

heath is the only person i have ever seen to break 2gpw.. i respect him as much as any grower out there. and honestly would you rather have 10lbs of fat colas or 11 lbs or nice sized nuggs? size is not the issue here, weight is

and i would say the optimal setup for 2 600 watters would be a 3x6 foot area, using a sog style grow

could not agree mor i built my rooms to get around 60 watt per square foot my 2x600w is bang on what you say 3x6 = 18 sf my 1000w room is 4x4 =16 sf

2x600 = 66.6 watts sf
1000 = 62.5 watts sf

i use all the area under the 2x600 to the best it can be used SCROG and iv done sog also there is no other way of doing it the room is only 4 feet tall its a good productive room but i get more out of my 1000w room that uses less power.

heres what i find plants grow in 3D light when a plant gets light all over it it will grow faster than if its just getting light over the canopy that will result in top colas being much bigger also the light gets down in to the canopy and you get more bud under the canopy you get just as much under the canopy as you do above it.

why do i get more bud under a 1000w in a 4x4 room than 2x600w using more watts per square foot in a 3x6 room? i think its because of the fact that plants grow in 3D light and not flat canopy or square foot of space the 1000w will grow worth while buds 3 feet under the canopy the 600w will grow worth while buds 2 feet under the canopy so over all the cube space is bigger under the 4x4 room than it is under the 6x3 room i.e

3x6x2= 36 cube feet
4x4x3= 48 cube feet

the 1000w room as 12 cube more feet to grow bud in than the 2x600w dont forget plants dont just grow flat or 2D they grow in 3D light there is a lot of bud under the canopy to.

here is the 2x600w as you can see the canopy is full

here is my 1000w room

and what each of the 16 plants look like

if i had to give up one of my rooms out of them both i would give up the 2x600w room.

na im talking what grows more bud 1000w grow more bud than 600w be it flat or be it tree grow the 1000w will out yeild the 600w even 2 of them if you going to be like that then comare a 600w to a 1000w is comparing apples to oranges the thing is m8 i have both systems a lot of ppl on here only speculate what will grow more the big diffarence is i know what grows more i use them both.

well you are confusing the shit out of me talking about 3D and 2D lightning LOL

and like i said i have grown with both as well and i believe that all conditions being equal a dual 600w setup will outperform a 1000w grow. it does not seem that your conditions in two rooms are not equal

take a 3x6 ebb n flow table, with 2 600w lamps, 64 plants from clone, and a 4x4 table, 1kw 64 plants from clone, same strain, same nutes, same temp and rh conditions, the 2 600w will win every time. been there done that, thats why i use 600w bulbs now :mrgreen:

gotany pics to show ppl that what you say is true or should they just take your word because you say so?

600 can be better than 1000w if you have a longer room and its not square im not saying that its not better what im saying is out of the 2 rooms that have about the same watts/area the 1000w yeilds "me" more or very near the same if i put the 1000w in the 600w room it would not grow more than the 2x600s.

method of growing sog will win in yeild i.e grow more bud faster in the same space over time than any other method. 4x4 works perfect with a 1000w plant 36 plants in that area veg for 7-10 days and pull over an oz per plant do the same with a 600w and see how much you yeild try it with 2 if you like, it will be a close call and your using an extra 200watts to grow close too the same you will not grow 9 extra oz with an extra 200w may be a bit more may be a bit less not all grows are the same "my" finding is the 1000w is better than 2x600.

well you are confusing the shit out of me talking about 3D and 2D lightning LOL

when you shine a light on a plant and only the very top of it gets light the plant grows slower than a plant that gets light all over it that grows bigger fater top cola's in other words you have to take in to account that square foot of growing area is not what you should go by, its the cubic foot of grow area that you should take in to account because you get bud under the canopy as well.

right, as i said before there are a few applications where a 1k will outgrow 2 600s and apparently you have found one. however i cannot authenticate what you are saying or agree with you because i dont know any of the variables about your room such as ambient temps, canopy temps, airflow, rh, co2 ppm feeding schedule, number of plants, medium, pot size, pruning methods etc. are all of these factors verifiably exact in each of the two rooms? if they are not then you cannot make a justifiable comparison because you are comparing apples to oranges.

see the reply above, i have tried it side by side, and i yield more with 2 600w lights, which is why i now use them believe it or not. granted i am using 200 more watts and 2 more sq feet but its still more productive.

its not that a plant grows slower when only getting "2D" light as you call it, you are not taking into account that you are using a 1000w light opposed to a 600w light which is of course going to make a plant grow larger faster, so cubic feet is not what is causing the growth change, its the more intense lighting. i see what you are saying, and i agree to an extent which is why i said in my original post that if you are growing large plants, a 1000 is more effective because of the light penetration. so to each grower his own.

however when you take into account aspects such as vertical lighting, then a 600w is again more effective even when growing large plants because it can still reach down into the canopy from the sides.

9inch bigbud · Apr 9, 2009

have you ever thought that the 1000w bangs out more of the color light that a plant uses to grow? in other words the red spike is higher from one point of light than from 2 points of light saying the 2x600 put out an extra 40,000 lumans does not mean the plant uses the lumans, lumans are measured with the light that we see and the plants do not use light we see so the extra 40,000 lumans means nothing unless uless they are in the correct spectrum of light.

im not arguing with you i agree whith what you say.

so cubic feet is not what is causing the growth change, its the more intense lighting

a plant that grows out side gets the same light all over it top and bottom the max amout of light 10,000lux all over the plant nothing grows top colas the size of plants outdoors unless indoors you can give it more than 10,000lux all over the plant not just the top.

the more light you give a plant at the botom (indoors penetration)affects how the top of the plant will grow. think of all the leafs as all little factories feeding one big factory if all the little factorys are getting more light at the bottom they will feed the main factory with more energy to grow bigger i.e the top cola.

the same plant grown indoors that gets more light at the top than what these plants get in full sun yet the top cola is much bigger on the out door plant

regarding your previous post, assuming you use the same type of bulb the ratio of usable spectrum is going to be the same as a 1000, and i understand how bulbs are measured and that lumens dont matter, but in a bulbs rated spectrum is the same ratio of usable light whether it be a 150w or a 1000w bulb

and now you are really comparing apples to oranges..

first of all a plant grown outside experiences illumination from both sides due to the sun rising in the east, and setting in the west. it gets uniform light coverage which is what light movers try to replicate indoors.

second of all lumens measure the total output of light in a given time frame, wheras lux is a measurment of brightness equal to 1 lumen per square meter.

bright sunlight is hovers between 90-120k lux, not 10k.. so lets just call it 100k

so basically we are measuring 100k lumens per square meter on the ground.
now the earth is about 150 million meters from the sun.. to find the area of this globe we live on we use the eq. 4(3.14)r^2

so 4(3.14)x(150,000,000)^2= 2.83x10^23 sq m.

then take 100k lux/2.83x10^23 and we get 3.53×10^27 or

so you are comparing the growth from your 1000w bulb that has a couple hundred thousand lumens, to the sun which produces 3,530,000,000,000,000,000,000,000,000 lumens...

i also understand how a plants metabolism works and how mitochondria produce energy at the cellular level. but if you put all the light at the bottom of a plant, it will not grow up, it will grow out.. its why when you grow vertically the plants grow much more compact..

plants grow TOWARDS light, with more intense light, they produce more energy, and grow faster. and a larger plant will obviously produce more bud than a smaller plant, but the whole debate has been will two 600w lights ourproduce a 1000w light and the answer is still yes, in perfect conditions it will win every single time EXCEPT for when you grow large plants where light penetration is needed.

in a scrog, in sog, when lolipopping, when lst, or topping, whatever it doesnt matter, two points of light spread out, over a larger space with plants less than 3 feet tall, 1200w will always win..

nice copy and paste. yes you are correct 100k i agree its like comparing apples with oranges it does not chage the fact that a plant will grow bigger when it has more light all over it than just light from above = more energy to grow bigger buds penetration

regarding your previous post, assuming you use the same type of bulb the ratio of usable spectrum is going to be the same as a 1000, and i understand how bulbs are measured and that lumens dont matter, but in a bulbs rated spectrum is the same ratio of usable light whether it be a 150w or a 1000w bulb

yes same spectrum but the peek is not going to be the same we know a 1000w is brighter than a 600w so it makes sense if the spike in the red is higher. all you are doing with 600s is putting down 2 lower red spikes of light over a larger area because we cant see the red spectrum of light how do we know how much red light each bulb radiates? 190000 lumans does not mean more red light is being produced as the bulb gets bigger may be there is an increase in how efficient the bulb is at turning power watts in to red spectrum light as you know plants dont use lumans to grow they grow using PAR.

.

in a scrog, in sog, when lolipopping, when lst, or topping, whatever it doesnt matter, two points of light spread out, over a larger space with plants less than 3 feet tall, 1200w will always win..

no it will not always win.

lets look at CFL grows for example adding more smaller lights does not grow more than 1 big light the same should stand true to HPS after all light is light
lets look at it the other way round the 1000s use 200w more i.e 2x1000w v's 3x600 over you 6x3 table the 3x600s will still have more lumans by 5000 but i bet the 2x1000w will out yeild the 3x600s penetration wins you have the canopy coverd the limiting factor then is below the canopy thats ware the 1000s will win and produce bigger cola's and more bud under the canopy than the 600s. do the same with 2x600s put them in a 4x4 room and put a 1000w in the same size room i bet the 1000w will still yeild more 1000w lamps grow more in the same area as 2x600 unless the room is not square. there is not a lot between the two

also 1200w is burning more watts than just 1200w a balast and bulb run at 10% more i.e a 1000w is running 1100w and 2x600 are running at 1320watts they are only rated at i.e 1000w and 600w but to run them takes more electricity than what the manufacturers put on the box.

Seriously? All that then you come out and say your room is only 4 feet tall....Well no Shit its not going to yield as much. Put your 2 x 600 in a real grow room and they will out perform your 1000w any day of the week.

Well, in case you dont know yet, light intensity Does add. So Yes. 2 smaller lights is like having a larger light, and in some places the light WILL BE MORE INTENSE!

This is well known. I dont know why you are trying to dispute it.

Because CFL's produce more of their light in the correct spectrums, but when you add them together you don't outperform HPS's. That's his point, light doesn't add like that. It might to your eyes, but it clearly doesn't work that way for plants.

If you put 150,000 lumens of CFL's in a room it won't grow plants like a 1000w HID. Should if light is additive right?

have you seen the cfl plant in seemore buds book?

2 x 600w HPS VS. 1 x 1000w HPS What will yield more?

2 x 600w VS 1 x 1000w

2 x 600w HPS

1 x 1000w HPS

Don't Care.
