HPS/CFL Combo. CHECK IT OUT!

I was spending some time with my girls today doing some thinking about lighting. I had been looking into providing some secondary lighting for the bottoms of the plants. My only problem was that I couldn't figure out how to do it, but I did know that I had 2 extra 42W 6500K CFL bulbs that I could be making use of. A little bit of cutting and splicing later I had my finished product. A custom lamp just tall enough to be even with the 5 gallon grow bags. I placed the new lamp in the centre of the girls and spaced them out evenly around it. Then I slightly bent the tops of the plants towards the hole in the centre so that every top would be right under the arc tube. The plants are getting some great light from the HPS above and now some solid secondary lighting from the CFL below.

What do you guys/gals think of this idea? Anyone think it may help increase my yield at all?

Not bad, not bad at all. It will help production on your lower limbs to be sure. How much improvement? Impossible to say but they look splendid so far.

yum yum yum... look a bit flimsy though...

What would you recommend I do to beef them up a little?
