sativa's don't do very well with low intensity light such as that. they'll grow and ripen ok but the buds are light and airy with a light yield. if i were doing haze and only had one flouro i'd be at the hardware store buying more flouro's! indica is better suited for low light conditions but even there you'll find less production and a poorer quality product than if you had used higher intensity light. any chance of you growing that haze under the sun? it'll do a helluva lot better and you'll be far happier with the outcome if they can be raised outdoors...
