These should be closing in to harvest soon, I'm hoping you'll share some photos or a video soon!
It's been harvested and a whole other run has taken place. There is a yield video and a lab results in here somewhere...you'll had to go back a few pages or go to my YouTube channel.

Now that I am looking back I see that my recent run is in this thread too. The in the garden series. ButI started a new and now to be continuous thread of my garden.

And you are correct...I just harvested. So we wait for the yield. As a grow...I can call it a very good one, best to date probably. I am sure the yield will confirm that when it's in.

Very impressive! Thanks for posting. Overall did you notice that the LED plants consumed more or less macro or micro nutrients vs the HPS? This is probably the best LED vs HPS comparison I've seen. Very close to 1.0 gpw with improvements within reach I'm sure. Bravo!

Holy sheeeeit, $2500!? lol Daaaaamn!

You get what you pay for! I've gone through 5 digital ballasts in 5 years before I finally said to hell with it and scored a magnetic. I love my LED lights for veg but it appears that the tech is finally relevant for flowering based on this run.

Thanks man. Glad you liked it.
I used mags when I had a warehouse. Reliable and no RF.

LED's are in the game for sure now. And only getting better by the day it seems. Costly at firsts but after years of perfect operation and much lower monthly power dues...they pay off no prob, even these expensive ass lights.

Not sure if you saw/came across the grow I just did...

And I got the next one vegging out right now.

Killer.... Those the same lights or different?

New to this site. Just ordered my at600 can't wait to get it. So you pulled 503 from 6 plants using the at600. In a 4x4. Do you use the srog method? I have 4 liberty haze in a 4x4 under a 440w until my light arrives. Day two of flower. Veg for 2 mo.

Not according to my experience. Top shelf bud in organic soil, testing 25%, clean bud. .66 gpw not bad at all.

But how much he pulled is completely beside the point, the comparison between the lamps is what matters. This is the ultimate way to compare the efficacy of 2 lamps so this is a critical data point.

Another way to look at it, if you think you could have got .9 gpw with that HPS, then you would have got 1.3 gpw with that LED.

Not to mention the fact that we're on V2 of the COBs :)

I just want to say thank you again for this. You rock and are 1 of the few at RIU I respect. I use your thread to show heat issues and how led uses way less heat. I have a few arguing with me that a watt is a watt and the heat is the same. I just tell them they are wrong.

All radiant energy emitted by any lamp is eventually converted to heat. So they are not wrong, you are.

Your welcome.
But they are correct. All watts are converted to heat. The benefit is that with higher efficiency more is light before it is heat so you can use less wattage to accomplish the same amount of light.
It's that less wattage that gives LEDs lower heat.
Another thing is that hps emits strong 850nm (heat) that is felt in the beam and on the canopy.

Now it is my understanding that the 850nm heat wave can be beneficial for driving plants to transpire. One led company actually was telling me that best performance would be seen by incorporating a small amount of hps (150w) with led.
In an area were temps are cooler, could you see a scenario where hps outperformed led in transpiration and photosynthesis?

25% makes me dizzy.
