Hps Vs Cmh Vs Led

[G gnome]

Pot is not sold by units of volume its by weight. If it was based on volume everyone wud be growing the biggest, fluffiest buds possible.

Ok. 700w for what size space? 4x4?

4x5

It would be fun to see a side by side in three separate rooms. Since you're already using less power and less nutes on the led/cmh side, it would also be interesting to see if there are any differences in power consumption of AC. Like annual costs for each system. Add the bulbs to be exchanged regularly with cmh/hps compared to initial costs with led setup. Draw a line after a 5 year run.

The weight on the 630watt cmh compared to the 600 HPS was about 8 ounces over.you think I dont know this stuff?i know when one light outperforms another.be like you saying there is no comparison between a 400 w HPS and 1000 when clearly you will be able to see the difference.
I get it man you like hps.but compared to cobs there is none I did a friendly comparison.this wasnt done in a lab with seperate rooms etc etc.
But if you want to look at par numbers on hps compared to led and cmh they are widely available.on a per watt basis there is no comparison

4x5

Ok. 4x5. 4ft x 5ft =20sqft. 700w ÷ 20sqft=35w per sqft.
W my de1000w i am covering 36sqft (6ft x 6ft). 1000w ÷ 36sqft = 27.7 w per sqft.
So, i am actually able to cover more sqft w less watts (from the wall)

Another thing is....u cant tell simply by the looks of the plants/buds. Theres no definitive evidence until it hits the scales.

put 700 watts of cob over a 4x5 and compare that to any 1000w hps bulb you have.

Each row in the pix is 6ft x 12ft.

Come on man really,your telling me the outside footprint is actually giving you the same as the center footprint and 6x6 on a de with no overlap is fantasy land

Ive looked into switching over to led extensively for the purposes of saving on electric and have come to the conclusion that i wud actually have to use more watts from the wall to cover the same amount of sqft

Exactly my point.those big footprints are made for overlap.a single de 1000 is good to about a 5x5 with a concentrated reflector.its on nanolux website and gravita.they set those up on 5ft centers not 6 foot

Pix to prove it. Notice the perfectly uniform growth side to side and end to end.

Just to be clear i am not dogging ya. I appreciate the discussion.

I know that what they say but the proof is in the pudding. Im runnin 1k de on 6ft centers w results

Bot when the last 2 feet of your footprint is in the shadows.get one 4x5 cob setup and you will single handedly fall in love with that technology.
There are different configurations for the way you light them.i chose to use 35 watts a square foot but that 35 goes a long ways.i cannot really explain it but the differences in growth and bulk is unreal.you get stacked colas from top down into and below the scrog.the first time I used them I noticed a difference right away.
I highly suggest you get enough for a 4x5 and just try them and see how much weight u pull.
Buds under cobs are far from fluffy lol.trust me on that

 

[Toaster79]

Did you guys ever bother measuring the actual power draw of a 1k hps unit? Is that 1k on the bulb or on the socket?

 

[heisen]

I know that what they say but the proof is in the pudding. Im runnin 1k de on 6ft centers w results

Any pics of 6 week flower?I really find it hard to believe that a de pulling 1200 watts from the wall not 1000 can grow buds on the outside as far as the inside.im using 1000 watt HPS in Raptors without glass (bare bulbs) and still get that hill effect

I'd have to agree , 750 Watts of DE HPS over a 4x8 area with no overlapping lighting.

Those 1000w DE are actually around 1200.thats what nanolux and gravita says.

Yeah man that doesnt look like 4x8.lets see the short side

Im not entirely sure what ur asking/saying...? If ur asking if i think my light intensity is the same directly under the light as it is on the outskirts of the light then my answer is no i do not think so at all.

Ive already proven (mathematically) that i can cover a larger spread w less watts w a 1k de. So, now the argument/discussion wud naturally evolve into a question of gpw. So let me ask u, what r u averaging gpw?

You cant just make up a footprint cause you say so.i can make my footprint a 6x6 under cobs by spreading out the heat sinks so your math didnt prove anything.there is no denying that led flat out produces more uol per watt.that is just a flat out fact.a significant increase.
But to say your footprint is bigger than mine just cause you want it to be dont mean anything.your de is around 1200 watts to be fair.im telling you I have ran hPS and cobs and cmh and think the cobs produce better.i can put a 1000w single ended 10 feet up in a 10x10 but that doesnt mean that's its footprint.
Until you at least try them this argument is dead in the water.
