Tomato Plants are not producing....

[T'Mater]

Ok new ?, what size dripper's are you running and how do you keep those booger's from clogging up?

I'm about tempted to not even run dripper's....

Also, it seem's i'm getting flower's but they dont seem to have like the yellow flower part's, just the green outside what's that mean? Mind you i've just got the set up outside about a week and am seem a big improvement and haven't gotten to see what the new flower's are going to do so this might be a premature question.
