Thanks. So they're quick not to understand? Sorry man, just messin'. I felt the 'like everyone else' part was enough of a confirmation that if it worked for them, it would work for you (for a few weeks at least). I was going to add a 'and you'll be fine' or somesuch onto the end, but then my smartypants line lost some of its' punch. If you were a bit slower not to not understand, you might not have not understood . Probably. Anyway, so as to clear any confusion, I will now state plainly: Yes. Those 2 42W CFL bulbs will be enough to grow 1 plant efficiently for a month or so. Welcome to the city.
