You have to consider the height of the bulb, intensity, and the top and bottom 'dead zones' of the small bulb. I had plants 12"-14" from my 860w. IMO CMHs don't have the bulb length and intensity for a tall vert...unless you keep plants close, use at least 3 bulbs, or have a light mover.
The Agro T12 would have to be very close in vert. Maybe stack 2 or 3...or put on a light mover. You could always get an 860w for only a $100 (requires a 1000w MH mag ballast)
I have a 3 Cheese Candy's that're off too a good bloom. Northern light blue and Marmalate were both very tast, potent, stank, and dank. IMO (just like any breeder) you'll have to hunt...at least you're getting girls.
