How to best add Lumigrow ES330 into flowering mix

Howdy folks, Just picked myself up a Lumigrow ES330 to add to my 600w & 400w HPS that I already use for flowering. I presently have 2 grow tents for flowering, one with the 600w HPS & one with the 400w HPS. Since I have too much heat already the Lumigrow fits the bill. I was planning to get a 3rd tent and put the Lumigrow in there. Since I can control the red & blue with the Lumigrow I was thinking of starting the plants in the Lumigrow tent for the first couple weeks of flowering and then transferring them to one of the HPS tents. I was thinking that finishing the plants under the LED makes sense as well. Does this make sense or would you just leave the plants in their separate tents for the entire flowering time? Any thoughts or advice would be appreciated?

how big are your two tents?

I have 2 4x4 tents and was planning on adding one more. I also plan on adding some CFL's or T5's in the LED tent.
