Did you read the argument even? What does it say? Its right there in the second sentence. Please read, then ask again, if still unsure.Bonjour
what do you mean you dont like the gpw!!11
CU
you need to get past comparison...this is not what I am talking about...but you aren't using math to make the comparison to even start....what are the raw number for the 440's vs the 600w HPS?
Strains, etc? What was the PPFD for both lights, any other variables....
and in reality you are comparing single die diode's to HPS....single die diodes that may be 30% to boot, so yes, efficiency is a big deal, since it is related to a variety of parameters, most notable...raw photon output, which can be compared between different light sources.
Again beating a dead horse, Efficiency itself isn't the # you need, but taking into context using math, will allow you to calculate PPFD or PPF and at least have a comparison to make between TWO different light sources.Again, I do not need to be sold on efficiency. I get that by the numbers they are better and I want to go LED...
But in a run I want to yield as much as I possibly can....
Anyway, a pic of the grow I mentioned above...
Then know your PPF, regardless if it HPS or LED, right now, you KNOW NEITHER!you need to get past comparison...this is not what I am talking about...
I want to yield as much as I can every run... paying a little extra for electricity to gain a lot is worth it to me...
Sorry couldnt resist,everytime I hear people yakking about gpw I think of littlejacob.Its called a joke,didnt mean to toss you into your period bro.Did you read the argument even? What does it say? Its right there in the second sentence. Please read, then ask again, if still unsure.
Sorry mang, the last couple of weeks, I have felt in the correcting mood...My apologies, sometimes its over my head before I even beginSorry couldnt resist,everytime I hear people yakking about gpw I think of littlejacob.Its called a joke,didnt mean to toss you into your period bro.
SolarStorm 440 draws 320 watt.... except for when time is added to the equation, at least in my limited experience. Meaning... the HID plants produced roughly 30% more in slightly less time.
Regardless of what math is used to prove efficiency, the 30% more yield in the same space and roughly the same time is a HUGE factor.
This experiment of mine, while not scientific, matches what I have heard from others who grow around here with LED.

True.Then know your PPF, regardless if it HPS or LED, right now, you KNOW NEITHER!
So my mistake was believing the manufactures claim that the 440 was the equivalent of a 600w hid.....SolarStorm 440 draws 320 watt.
2 Solarstorm 440s next to 1 HPS 600 watt (this is excluding the energy the ballast uses) is a fairer comparison.
Your 640 watt combined LEDs did 9 ounces, your 1200+ watt HID did 13 ounces.
Easy to see which of the 2 performed better.
A 600 watt Vero or CXB fixture will easily outdo a 600 watt HID fixture.
Your HID plants where under lights that consumed twice the amount of energy.
HID does not give more yield you simply doubled the wattage.
Your experiment is basically this.
I make a 5 watt led fixture and I compare with a 1000 watt incandescent fixture.
The plants die under the led while the plant under the inscadents flowers.
I then claim that inscadent provides more yield than LED.
That's what you just did figuratively.
Please use science to explain your basis for making that pronouncement.640w of led will not produce more than 1200w of hps
what kind of HID are you talking about, since they've def advanced too.What LEDs are you talking about?
There are a lot of manufacturers with different standards and efficiencies.
High quality COBs easily outdo HID lighting.
It was a breakdown of his experiment. He yeilded 9 ounces with 640w of solar storm 440 and 13 ounces with 1200w of hps. He concluded that hps wins. I disagreePlease use science to explain your basis for making that pronouncement.
