I have a friend that just pulled 42 lbs off 10 plants indoors in 6 weeks 10K worth of lights.
Sounds unbelievable but so are the pictures

They are actually using 14KW in lighting...... which makes it just under 3 lb.'s per 1000W of light.
They actually flowered for longer than 6 weeks.
They used CO2
I browsed through the thread real quick, and didn't see any finished product shots.....
Why should I believe the weight?
Everything else is being grossly misrepresented.
How many grms is a lb to them?
I have seen this link posted all over the place..... But very little info about the actual grow.
Aside from "claims", Im not impressed.....
