Took you long enough how many times did you go over that response

:laughing::laughing::laughing::laughing:

It's called priorities- you're not one :biglaugh:

And why am I not surprised you that you find the idea of taking time to check posts foreign? :chin:

and from the beginning I stated where I got the info from and that I just ordered it, I dont like to argue over the web, because people like you talk crap, you are sitting behind a computer just like me I am on here to learn what I can and I take all that with a grain of sand, because nobody knows it all and what works for one person might not work for someone else, so why dont you stop acting like you know it all, I hope that is working out for you being so clever, take care I am done arguing with you, no one ever wins these types of things..

There's the crux of your problem. We're here to learn, but you refuse to do so.

We're not discussing opinion here. There's nothing to win.

Math is math, period.

I'm not the one saying you're post was wrong, Math is, I'm just his translator. :D

you don't get it do you a 6 is better than a 1000 because of the lpw it has 10more lpw than a 1000 that is 7% more than a 1000.. Lumens emmited are only part of the equasion lumens recived by the plant are much more important lumens recived are measured in watts-per-squqre-foot or foot candels one foot candel equals the the ammount of light that falls on one square foot of surface located 1 foot away from 1 candel. lamp intencity doubles every 6 inches closer to the plant get it yet.....


a 1000w with 140 lpw@ 4 feet= 10.000 lumens
a 600w with 150 lpw@ 3 feet= 10.000 lumens

4x4=16square feet,1000 watts/16 square feet = 62watts per square foot
100 watts/m2=100watts per cm2

3x3=9square feet,600 watts/9=66 watts per square foot 600w/m2=6watts per cm2

the relationship between light emitted from a point source (bulb) and the distance are defined by the inverse square law . This law affirms that the intensity of light changes in inverse proportion of the square of the distance

I=L/D2

Intencity= light output /distance2

HiD's are bright growers who properly manage intence brightness harvest more weed per watt. Intensity is the magnitude of light energy per unit of area It is greatest nearer the bulb and diminishes rapidly as it moves away..
for example plants 2 foot away from a lamp recive one-fourth the light by plants 1 foot away a HID that emits 100,000 lumens produces a partly 25,000 lumens 2 feet away (60cm) a 1000 watt that emits 100,000 inital lumens yields 11,111 lumens three feet away (90 cm) couple this megar sum with a poorly designed reflector and beautiful buds suffer big time.. the closer a plant is to the light source the more PAR watts it recives and the better it grows, as long as it is not so close that heat from lamp burns the foliage. with a high quality reflector made from non conductive matireals heat escapes faster and there is no dancing with the devil...

under perfect conditions plants that revived less PAR matured slowly and produced less

for exanple a 1000 watt that produces 100,000 lumens at source produces the following.. the goal is to give plants 10,000 lumens if you use 3 600w you get a total 270.000 lumens at a cost of $0.18 per hour(cost per kwh = $0.10)
If you use 2 1000 watt you get 280.000 lumens at a cost of $0.20 per hour
use the examples above to see how the 1000 watt offers more watts per square foot amd m2 to achive the desired output of 10.000 lumens, however the bulb also produces a hot spot in the center of the illuminated area. Plants tend to grow into hot spots and shade other plants although a 400w has a lower lumen per watt conversion, when used properly they are more efficient than higher wattage bulbs. One 1000 watt halide produces 115.000 initial lumens and a 400 watt 40.000 this means that each 400watt needs to be lowered to produce a similar ammount of light it also means several different light point sources sustain more even intence light distrubution.

A 1000 watt with a "hotspot" must be placed 36 inches (90 cm) from plants
600s can go as close as 18cm with a hood that reflects light and heat evenly,, when placed closer a 600 produces as much light a a 1000. The propper reflective hood over the lamp and reflective walls walls double the grow area growers that use the most effective hoods harvest up to twice as mush as those who don't....

One option is to remove the hoods as with no hood lamp burns cooler and emits only direct light.. or a light moover but these still make 600's the best..:dueli ng:

You make excellent points, except that your argument hinges on this statement, which is incorrect. A properly cooled 1kw does not need to be 3 ft(!) from the plant. It can, in fact, get as close as a 600.

Pac-Man:

Apologies for shitting up your thread :bat: I think the 600w is the right choice for you from what you've described. Just shrink that space to 3x3 using poly (or whatever you'd like :D), and grow on! :yes:

And now you know more than you ever wanted to about calculating electrical consumption :redface:

My statement also says Growers who properly manage there intence brightness harvest more weed per watt & growers that use the most effective hoods harvest up to twice as mush as those who don't.... lol... keep up the work and don't forget to put more than a spindle under a 1000 Night tiger.. or you are better off with a smaller lamp me thinks

Old old pic man ('06) :D

Those were 'canaries', a run of bagseed just to make sure the room was running properly before sticking high value genes in there. :yes:

I just ordered a adjust a wing reflector with spreader with a quantum ballast. 600 watter too. U don't have to apologize to me it is what it is.

Yeah, I'm pretty lucky where I'm at, $.06/kwh was my cost. Just went up to $.08 this latest billing cycle. Still good though :rasta:.

I'm in the same boat I still only pay $.055 per kwh
