Adding a 2nd light to my setup?

Check my sig. link for a full photo of my setup, I was wondering if anyone could tell me whether squeezing maybe a 250w MH light or maybe a few strips of flour. tube lighting places under the foliage would help for more bud production?

Would there be more probs. with condensation down there?

Many thanks!

Nah go for it, more light the better! just watch the temps....

It will be alright, but make sure the lights arnt facing each other, because they cancell each other out if they are.
