OP might be thinking about umols/joule #'s with a 2.7 but on the off chance this is true I have 16 panels of Kingbrite's QB288(1920W total but I run at 50%) so that'd be interesting
2.7 grams per watt Leds, truth or hype?

It's the new ad hype I've seen lately.
Tons of lights now list "2.7gpw!"
I figured it was BS, I just wanted to get some real opinions from peeps on how their lights actually performed for them. Not some algebraic equation of what they "should" be harvesting.

Maybe it's umols I saw. IDK. Again, I was just looking for some honest answers about what people were getting from their Led's.
To those that answered honestly, thank you.

Link to ad?

Don't have one. Previous dude was correct.
It's 2.7 umols everyone is advertising. Not gpw.
Good thing too, my e-penis was getting smaller by the day thinking people were pulling 2.7gpw...

Gee I wonder why the journal was never started.
I forget his name, was a master grower for some big grow op, easy for him he claimed. Obviously nobody believed him. Just trolling I'm sure. I'm waiting for the ones who say you can grow with only water and no nutrients, haven't seen that claim in a while. It's like the grow version of when people convince others to put sandpaper on their windshield wipers to easily get rid of ice in the winter.

I'm already enjoying the ability to control my environment more easily and precisely even with just 1/2 the tent swapped over.
There's a lot more benefits I'm starting to see from the Led's than just the light themselves.
Some are advertising gpw now..... the latest evolution marketing bs.

Your not entirely off about the adds claiming enormous yeilds.
My SF light claims 2.5 gpw which is a joke.
If I pulled that, I would be getting almost 4.2 lbs out of my 4x4 tent

And every legal grow op would have a shitload mounted and running.

I'm curious to try selecting a mother based on gpw, or PPFD etc... Something that does well under weaker light. I feel like nobody talks about this.
I guess if you had an entire basement to yourself, and a plant that is happy with 1,000par or less you could make some breakthroughs.

I mean, the thing is that that is obvious.
But the genetics just can't make up the difference in yeild that a low quality light vs high quality light will give.
On top of that, not matter how good your plant does under low light, it would do better with a strong quality light.

I though LED was for growing just mother plants? You've seen people flowering with them?

I have a strain that will under produce if you hit it with too much ppfd. So, where does that leave us?

Sure I'm just saying if you had a whole house, only limited by amperage..... I wonder what strain would do best with a big distance to the light i.e. Weak light.
Like 2,000sqft but 6,000w hps etc.
I mean, I've never bothered to put various clones under t5's and flower them for weight for example. Only flowered under floros once, and it was two LA confidential seeds.
But my point is, maybe some of the "non-keepers" would actually be "mothers" under weaker lights compared to the "studs" under 2,500par etc.
