Hi growers!
The highest gpw I saw (with 6 weeks vegg I guess)was from Growmau5 I guess it was cxb3590 @700mA and he pulled 1.9gpw so in a controlled environment with co2 clones and a perfect nutes plan I believe you can reach a bit more than 2gpw since it was the 3500°k CD and DB are now available it is more than possible!
I guess cxb3590 are 180 lm/w but now we have the Samsung QB288 who is 220 lm/w so I just wonder if you use it the most efficient and effective way could we pull 2.5gpw!???
If you have link to some grow log with big yield it would be great!!!
I never saw any HPS grow pull more than 1gpw and even 1gpw is not easy without co2 a/c hydro good genetics and 2 month of vegg!
Have a lifted one and lots of good vibes from France growers!
