I run a 1000w digital dim able it's awesome. Best bet for ya. More light the better but temps are usually an issue in tight spots. A cooled hood helps loads and the dim able option helps when temps get hot. The plants don't mind "brighter" days than others. It's almost like replicating cloudy days. There's a lot of ways to save cash but DON'T go cheap on the lighting or it's not really even worth doing it. I have a buddy that runs only cfl's poor guys puts in months of work to get maybe a half to an ounce off of a plant. So he didn't save any money it just cost him about 110 to 180 dollars in electricity and four months of work for that when I hit ten plus ounces without much effort or even training. When I do train lst, super crop, topping, I grow more on one plant than he has in three years with all his plants combined. And we run the same genes cause there mine so it's not the plants. It's the lights. SPEND THE CHING!
