I have a 6'x4' table with 20 plants at 1' apart both directions. and a 1000wat hps. should i have more light? i can almost get 1 oz. per plant at 18'' tall. can i do better or is that average.i dont have a camera sorry and my phone takes crapy pictures, hope to get one soon.

You are at about 55% there...

Here are two guidelines that I have learned and tried to fall between:

Minimum 2000 lumens per sq.foot (for plant growth)
Maximum 75 Watts per sq.foot (to avoid bleaching and heat stress)

I think you could add another 600-1000 Watts (<-- might be pushing it) and definitely increase your yield.

Some pics would be a nice gesture.

You could deffinately use more light....Only an ounce per plant? Sounds like your 1000watt isnt enough.
