Jerry,
I've always been clear that my LED advice is solely my opinion, based on LED research and my signature makes that very clear. Nobody here has ever been required to take my grow advice.
I always ask about things like grow area and grow style, even in this thread and your "my questions" thread.
I don't recommended a single SF for a rectangular space, especially for flowering.
I don't recommend flowering with low w/sqft numbers nor with weak diodes (unless the plants are very small) either.
I suggest that you go back and actually look at my advice before criticizing it. While I haven't grown with LED I do have a lot of grow experience and many people here have benefited from my advice. Finally, if you had read the announcement threads you'd know that I was recently given a SF full cycle light that I will be testing after my back surgery. I may or may not flower with the SF since it's such a small light but I will be testing it in various scenarios.
Hope that helps...and please don't dig up threads that have been dead for several months. If you want to continue this new topic I can split it off of this thread.
