check out my grow in my sig. lower wattage is needed for veg, but i typically run each plant at 60-80 watts each throught their life cycle. 3 23w will be enough as long as you keep your plant close to the lights during veg, and do yourself a favor and apply a little training (lst or topping) to your plant for a bigger yield at harvest. because cfls do not have the canopy penetration that hid's do, it is very important to train your plants to maximize the harvest potential of each plant. ive always used hid until about a year ago, when space limitation became an issue. i am very satisfied with the cfl production and have set up several other people with them as well. if you need help hit me up, or hit up any experienced cfl grower on here and they will help you. good luck
