Calling all LR2 growers! (Diagram Pic Included!)

I was just curious as to how wide the LR2 strain can get. I have an 18" x18" space and want to grow four side by side with a heafty 105W CFl in between them. I'll also have two 42 watters for the two than are just veging. If they get too wide can't I just string them up to make them narrower? The way I see it is I have an 8" diameter per plant I can work with.

I've included a pic of the design. The box in the corner is a air iodizer and O3 generator. It says 480 square feet on the front. Will this be good enough for the smell?

Ozone directly by the plants can cause leaf spotting, might wanna try putting the ozone outside the cab.

So if it were outside the cab then the closet wouldnt smell?

I have no personal experience with ozone only stating facts I know to help your grow. Look at me ma I can Rhyme'

K scratch the O3 generator, I'm going to get a couple of those air purifying CFL's after reading a postive review of them on this site, from a user growing LR2s. Now with that big box gone it opens up room to move the 105W more into the center making a wider space for the plants.

Sounds like a plan, I personally have no experience with those bulbs, but if all else fails you can make yourself a nice small carbon filter later.
