I used those on a previous grow. I got 1 (2 light bulb) fixture to sprout them, 2 fixtures to veg and a 3rd to flower. I still think it wasnt enough lumens. The yield was really crappy and the trichs were reluctant to turn color and it took forever. If you had some cfl's clamped to the sides of the pots to compliment 2-3 48" fixtures that might be enough light. I'd save up a hundred bucks or so and get a hps before flowering.
