To me, that looks like a 5'x5' tent, but what do i know.The FC-E3000 is 2.1'x2.0' is it not?
So I guess there is either an error using a pic of a larger tent or I am getting my perspectives wrong.
Either way its an impressive grow from a single FC-E3000 and supplemental florescent lights.
Of course the question does not say that this pic an 3x3 tent with a single FC-E3000, so maybe I am just jumping to incorrect conclusions.
