There are "problems" with any rule of thumb. BTW, I prefer the
rule of thumb of 2-3W per gallon minimum for beginners. No matter
what fluorescents you're using, if you get above 3W/G, you will
almost certainly need supplemental CO2, which is _not_ where most
Since you think this rule of thumb is a bunch of crock, can you
suggest another, based on information _EASY FOR THE BEGINNER TO
OBTAIN_ (lumen ratings on a generic bulb are not available for the
asking at a pet shop or even the average hardware store) that you
think is better?
