Your opinion is VERY welcome, Mr. Belvedere. Because I have actually been named, shamed and called a liar on this very board for claiming to have gotten around 120 gram from a 250 watt grow.
The reaction I got was horrible, especially from one user. He downright called me a liar and calling me names like "JohnnyBigballs" etc. The dude downright said that ”if I did what I claimed to have done, then he was a talking monkey".
To the poster who said that: If you are reading this: It is not very nice to accuse strangers of lying.. And it is not a very nice personality-trait to think that noone else can accomplish more than what you are capable of. To think that your own skills is the pinnacle of what is humanly possible is... well. I wont even comment on such mentality. Sorry to come forward like this, but your reaction back then towards a newcomer on this forum was NOT ok. Maybe 0.33g/watt is the upper limit to you, but it is not ok to name and shame people, just because they are able to get better yields than what you can accomplish.
Sorry to the rest of you for this rant, but I had to let it out, and now back on topic:
I am now growing another batch. This time under a 200 watt CFL. And I expect to break the 0.5g/watt ratio.
Pics of my 200 watt single bulb CFL grow 5 weeks into flower:

What do the rest of you guys think? Do you agree with Belvedere that it is possible to yield a 1/1 ratio with CFL? And what do you think would be a more realistic goal to strive for? For me personally with no sidelighting and very limited closet-space I will be exalted for anything over 0.6g/watt (as I have a hard time seeing much more roomfor improving the setup due to limited space). If I had a bit more space, and put up some sidelights I would definately aim for at least 0.75g/watt. I'm growing on 0.4 square meters and the bulb could easily cover more than that. I also only use a basic nutrient, where some "top-max", rootjuice and whats not would help aswell.
I actually believe that a 1/1 ratio would be (close to) possible in a 100% ideal environment. If Mr.Belvedere has seen it done, who am I to question
