Sannies "Kolossus" questions

Ok so this is my 1st grow since 2005 and my very 1st hydroponic grow. current setup is

2x 400w hps
1x 150 hps
6x 4ft dual 40w flourescent tubes (hanging vertically along the grow space)
5x 6 plant 18 gallon diy dwc systems
and 36sq foot of space with plenty of ventilation

im gonna be using the bc recipe for success chart as my nutrients but likely only 1/2 the called for mix and the "kolossus" strain from sannie. I know there is never really an exact answer to a "how much per plant" question but im going for a SOG grow. Gonna veg until 15" to 18" then flower for 8 to 9 weeks in hopes of a 3 1/2 ft plant ready for harvest. Has anyone had any experience with this strain under SOG and if so what should i expect as far as yeild is concerned (a ballpark figure)? Also i will not be topping or LST due to space requirements. Any information would put me at ease being this is my first in a while and i have an extremely high investment already.
