Already got one from when I was running HPS! Now it barely has to do anything!
And boy is my environment as easy to control as ever!
Quantum Boards or COBS?

You can make up for the lack of UV by running a higher canopy temp. I run at 82-84F @ 50% RH. They explode in resin productionNo way bro. COBs have an inferior spectrum because they lack UV/IR, remember?

I Should've used DE Tech!
Oh well, I guess this will have to do.

pretty much right in line with the typical results i cited

once you included the ballasts it was 3250W vs 2500W
@ 0.15/kWH thats $493 per year in energy savings, not including cooling load (which is reduced from a pure BTU production standpoint, and reduced even farther when you consider plants under LEDs do better when the room is 5-10 deg warmer.
you shouldnt be comparing capital cost of DE vs capital cost of LED, rather (the capital cost of DE+extra required tonnage of cooling) vs LED
(and thats before you save $500+ a year on power)

Mango originally came to us for side lighting only. That is it. No intentions or thoughts about overhead. He ended up having some extra space in that R&D room, so we got him to try them overhead while waiting on the bigger room to finish. So we got to get some great data from a great grower on a larger scale. But for mango, that test was basically all a side lighting test. Since seeing that test, other companies , like next, threw lights at mango, but it is PLC that he continues to purchase from and use in his main rooms now. He works with many facilities and has our light in and going into quite a few.
His big rooms are are ready built out and equipped for the DE's. The way to improve them is to add the LED side lighting. Overhead will go into a lot of his new. It's not a one size/way fits all. It's about making the current or prospective operation as successful as it can be. And working with what they have and can do. The old rome wasn't build in a day I guess.
Where did you cite them from? Citing involves sources, which are the real evidence and backing of a statement. Citations are just the acknowledgement of someone else doign the work.

experience of myself and others
quit flexing man. your one anecdotal study is impressive but its really just another data point

Is it really that hard to come up with one or two somewhat documented "data points"? I'm not asking for a peer reviewed white study paper.

I like it...people talk shit about side lighting,but used at the right time/right amount. it definitely makes a difference...thanks for the reply.

in a true "side by side"? it sure is
your study didnt even have the proper temperature differential for the cobs to do their best vs hps
with all the different factors in spectra, temp, nute uptake, vpd, etc, its really hard to get a true side by side
so we are left with a mountain of anecdotal data with hps yielding 0.7-1.2 GPW and LEDs yielding 1.1-1.7 GPW pretty consistently

Dude why do you keep responding with nothing. It's not that hard to go into the LED bud pics, or LED users unit, or g/w threads and grab some elese results. That is literally all I'm asking for. That when you say "I cited"...that a source actually happened to be cited. No matter if you guess is wrong or right. A citation involves a source. As well does people believing what you say.

You never cite anything you just make claims off the top of your head, like this one.
and this one
You do know electric prices vary right? But we don't even know where you get any of this data , seems like it's just out of thin air. You also are saying yields are the same, but you have no data backing that up.
Also most are not factoring DE's are mainly used with overlap , so that is never factored in. Here's an example of what i mean.

Lots of facilities using setups like that , I haven't heard of a single one using LEDs.

For sure man. I was being totally sarcastic about spectrum as I grow under COBs myself. Sorry if I was confusing.

Well when @sixstring2112 @captainmorgan @Rahz @PSUAGRO @The Dawg @Growmau5 @Greengenes707 all show results that agree with mine im kind of done thinking about it and personally my hps are collecting dust
with costs down and people jumping on low power cob arrays and pcbs with augmentation combined with ever improving growing technique, really a consistent 2 gpw will soon be the next benchmark.
even that first stab at the test room, under hps growing conditions, your rigs got over 1.4GPW on their first attempt with LEDs, and those were probably cxb3590 CD at 1750 ma which its pretty easy to get 15-20% on between bin jumps and lower currents (the latter being a direct result of lower costs in that time)
im glad you have these opportunities and i hope you guys are giving them your latest vero rigs once they hit 1.6+ GPW im betting they never build another hps room.
i dont think thats your argument... you of all people know the numbers.

yes you can apply those gains to any number you have . ill make it real simple, its the kwh cost relative to 0.15 cents so while the people who are fortunate to only pay 0.10/kWh will only see 66% of the benefit, make sure to consider the growers in hawaii who are north of 35 cents who see well over twice the savings

Where are you getting "the yields are the same" from , because you have no proof you just are assuming that.
And electric prices are as low as .07cents per hour where i live in colorado.

You aren't gonna see shit for savings at those rates, you will NEVER get a return on investment if you plan to save on your electric usage.

i never once quoted a single electrical savings rate without prefacing it by "at 0.15c/kWH..."
thats what i pay
national average is 0.12
not that much of a stretch
