Using all fluorescent bulbs, you want more than 70 watts per square foot (actual watts, not 'replacement' or 'equivalent' watts).
Daylight bulbs are best for veg.
Warm white are best for flower.
Keep them close to the plant canopy to reduce stretching.
Sativa strains grow taller than Indica strains.
