in cannabis green houses they only use HPS lamps outdoors because the is enough blue light from the sun some plants do better than others under differant lights thats why LED are crap for cannabis, but are good for other plants cannabis grows best under HPS its been proven time after time in real grows not with some p.c program that looks good on the screen.

here is a green house that just uses HPS http://images.google.co.uk/imgres?imgurl=http://www.crop-lighting.usgr.com/images/hortilux_scheder_lighting.jpg&imgrefurl=http://www.crop-lighting.usgr.com/crop-lighting.html&usg=__xlF1lH8M3ZpMD45XiVV80aoGE74=&h=377&w=600&sz=26&hl=en&start=388&um=1&tbnid=Mz9qm1ZZ-d73IM:&tbnh=85&tbnw=135&prev=/images%3Fq%3Dgreenhouse%2Bwith%2Bhps%2Blights%26ndsp%3D21%26hl%3Den%26safe%3Doff%26client%3Dfirefox-a%26channel%3Ds%26rls%3Dorg.mozilla:en-GB:official%26sa%3DN%26start%3D378%26um%3D1

Ok, so HPS is *twice* as efficient is it? Fine, drop $60 on cfls instead of $30 and grow *twice* as much. You're still paying *half* as much for CFL...

9inch bigbud,

*facepalm*

Exactly right, they use it to supplement nature. It is not the exclusive light source.. nor the primary light source.

LEDs are not crap. Please refrain from harshly judging what you have no little to no experience with. They're getting equal or better gram/kWh.

again show me proof that LED's grow anywere near HPS or even CFL for that matter! there is no proff when you see police bust big grow houses what color light is always seen? is it a sort of warm yellow/orange glow? have you ever seen a bust where $$$$$$ of cannabis have been grown under LED or CFL lights? CFL's are not effective as HPS if they were then every grow house would be using them would they not?
ill say it again things look good on paper, but they do not look good on plants! plants use all colors of light exept green to grow that is why the HPS kicks CFL up the arse MORE light! not because its got more or less color its the Lux that the HPS give over the CFL's. the over spill from the extra high intensity grows the buds not because its lacking in the blue or red spectrum other wise on paper LED grown plants would be massive if it was down to just use of red and blue again plants use all the color spectrum of light to grow the extra over spill from the intense light from the HPS helps where it lacks in the red and blue light!

to grow the same amout of dope under a CFL as you would get from a HPS you would need more power i.e to get the same ammount of weed from a 400W hps you would need 5x125w CFL's thats 625w of CFL power to get the same result as the 400w hps thats not very efficient over the space the year think of all that extra cost in electricity! for the same amount of bud.

but the hps needs watts to cool it. leds have not shown many grows yet because hps has been around for decades. in decades from now we will be argueing that bvassLDF IS BETTER AT growing than led and all the led guys will be like show me a grow with jjfkkfdsh. it will catch on and take over. led is here to stay. in 3 years there will be no hps.

I love when cfl growers go to painstaking measures to try and justify their poor choice in lighting or lack of funds...while flouros are great for vegitative growth they just cant touch the sheer intensity of light penetration that a hps has....i understand what you are trying to say as far as the available light and spectrums per watt not just the lumen rating..Yes in that aspect you are correct, but why is it that an indoor plant has tighter denser flowering than a plant of the same strain grown outdoors? im not talkin about a simulation or something i came up with from reading several different studies on lighting...this is a true and factual statement that is from my personal experience...indoor product that is veged and flowered under hps is superior to my outdoor that is grown under the suns full spectrum.

you guys have no side by side comparisons. the hps guys that is. i have both and can say they can yield exactly the same. everyone has seen my setup. flouros can yield the same watt for watt

the plants on the left are bubble gum and on the right are purple kush..the bubble gum streched more than the kush so out of fear that the hps wouldnt reach enough i threw in some cfls in the 2200k spectrum to help out....after about 3 weeks the bubble gum continued to flower and fill in great but the kush still lagged...

so i removed the cfls and let the hps do its trick......and wouldnt you know it the kush started to catch up......weird huh?

you can't compare 2 diff strains. doesn't prove anything. plus i have 2 separate setups. 1 hps setup and 1 cfl setup and can say flouros perform the same. i've flowered under both. have pics to. but i grew same strain under each and got same yoeld per watt after cooling for the hps

plus in your other pic the cfls are like half a foot away. mine are half an inch away. i can see your setup throwing light all over the wall just like my hps setup. but my flouro setup wastes no light. all touches plants

what i know is what ive experienced.....Ive grown with cfls, ive tried leds and in the end hps will out perform everytime.....

The pics of the hps plants are just that. 450 watt hps. they look good. the t5ho setup grows buds the exact same and i don't even no witch 1 actually won because it was so equal. the t5s waste no light. obviously the reflector is off the t5s so i can get a pic.

9inch bigbud, If you can't form proper sentences and paragraphs then I'm not going to bother reading what you type. Seriously.

All bulbs are not equal: https://www.rollitup.org/2081469-post16.html

You can't compare them directly. As they don't produce light by the same methods, they produce different spectrums, and different intensities at different wavelengths. CFL, simply put, is a much higher quality of light compared to HPS. Quality is used in reference to comparing bulb illumination to the sun.

Meanwhile, check out Google, and what PAR is, and why it's the end-all-be-all of plant lighting and not lumens:
