HEAD TO HEAD...LED then HPS
CANNABINOIDS: Total: LED=27% HPS=25%
THCA: L=25%, H=22%
THCAC4: L=0.74%, H=0.74%
D9THC: L=1.7%, H=2.0%
D8THC: L=0.11%, H=0.095%
CBNA: L=0.091%, H=0.081%
CBDA: L=0.08%, H=0.067%
CBCA: L=0.047%, H=0.046%
CBGA: L=0.23%, H=0.13%
CBG: L=0.15%, H=0.13%
TERPENES:
Terpinolene: L=0.087, H=0.13
Linalool: L=0.089, H=0.088
Beta-Myrcene: L=0.63, H=0.51
Alpha Pinene: L=0.58,H=0.59
Limonene: L=0.098, H=ND
Notic how limonene isn't even detectable in the hps sample.

Thank you greengene's for your awesome work.

That's a new one to me, hps has 1 source of light mainly 1 bulb that outputs 1 spectrum of light of 2100k light, now you can use white lights in LEDs of similar color and you can also use red lights, blue lights, cyan lights, amber lights, deep red lights, UV lights, far red lights...and the list goes on while the hps is limited to 1 source of 2100k light.

2100K is not "a color" or a spectrum, but a specific proportional mix of ALL the colors.

Thanks for saving me trying to find it.

2100K is not "a color" or a spectrum, but a specific proportional mix of ALL the colors.

The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is only meaningful for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.e. those on a line from reddish/orange via yellow and more or less white to blueish white; it does not make sense to speak of the color temperature of e.g. a green or a purple light. Color temperature is conventionally stated in the unit of absolute temperature, the kelvin, having the unit symbol K.

The 2100k is the color temp of the hps light. which is an orange/reddish tint.

Do you realize that agrees with my statement, but just gives more detail?

How does it you said its not a color, it specifically says its a color.

 

[a mongo frog]

They don't.

i didn't think so. I've seen some awesome led grows on this site, however saying better buds is just kind of funny. i don't know if any one remembers sleezy1, but he grew some dank og using leds. he never said better buds here better buds there. good farmers grow better buds and thats it.

 

[Da Mann]

I am just about done with a grow. Used Kessel lights. Buds are huge. But you can shine a
light thru them.

No, it doesn't. "Color temperature" is a measurement of a mix of colors, not a specific color. Read it again.

Hi have a look at this
Lumigrow pro325 led just love LEDs

Something i read over some places i will try to resume it.. its seems true to me

Pure hps ( only red Spectrum ) have allmost none UVB output and with a cooled wood or a glass shield it reduces it to none ..
You will have higher yeild but lower quality ... thats why leds with uv output can put more quality..
Most top growers now flower with MH bulbs combined with HPS and in the final weeks take off the MH hood glass so there is none UV Filtering.
UVB rays make the plant protect itself by covering itself with alot of resin . increasing this way the potency of the bud.

back to the topic of the thread .. why dont you try a cooltube ? with singular exhaust drawing from outside the grow and connected directly to the cooltube ? but blowing to the lamp not pushing !

 

[Red1966]

HPS has much more than just the red spectrum. Red is not even its primary output. LED UVB diodes are very poor performers. This is why CLW uses fluorescent tubes for UV.

 

[Lysergicpt]

I'm not in defend of LED i myself use now Reptile lamps , cause i had to switch to cooltube cause of the temps this summer , i had bare bulb dual spectrum.. and allways get sticky resin , but now the tube filter the UV and i added some extra reptile
Just saying going only Pure HPS is not the way to go , unless you just care about big yields

Totally agree pure HPS will give you big huge buds of average quality that aren't fantastic. ANNNNDDD when you live in a state that weed is legal you want fucking fantastic , so I tossed my old HID equipment and started experimenting with LEDs , reptile bulbs and hydroponics, would like to get a plasma light but they are kinda expensive right now the one I want is almost 2000$.

My current LED setup with reptile UV-B resin booster, just harvested that plant and it was gooey and smelled like straight hash/indica dankness.

big huge buds of average quality,what a load of nonsense.genetics and the way the bud is grown play a huge factor too.the greengenes fella said the difference between the bud was barely noticeable.so hardly a massive difference in quality.it was more or less the same.im just suprised he didnt get a better yield from the hid light.led lights are good,i have been thinking about getting a 1600 mars II,but i live in a cooler country,and im worried i'll have to use a heater in winter when using the led lights.this will end up costing me more than using hids.ive been trying to find out how much heat a 1600 puts out...is it the same as a 400,600,or closer to a 1000 watt hid.im talking about the heat under the light,the radiant heat,not the heat that comes out of the top of the light which will be extracted more or less straight away.

LED is great for energy savings and lower heat, We know this. Cree lights are offering the spectrum our plants want. To build one is challenge tough. LED wins for now.

You wont get much heat from your LED maybe some might come off the top but the light doesn't really produce heat like a HID I can touch my LED diodes without being burned they are only warm to the touch so I doubt you will get much heating from your LEDs in the winter.

see thats a problem,coz i agree these new powerful leds perform well.its alot easier to achieve a gpw,but if i have to have heaters on to keep temps up,the energy saving leds give you, wont apply to me.i'll just have to stick to my 1000 watt aircooled until i can figure something out.
