This is my first go around so I used some bag seeds from some really good bud. I planted them straight in the soil and most of them sprouted and look to be doing fine. I have been reading on here and am getting mixed signals. Some say that flouros are enough light and some say that during veg and flowering stages I need to upgrade. I have a closet set up and was not planning on more than four or five 4 ft. two bulb fixtures. Will this be enough to support three four foot plants, or do I need to upgrade? Any advice would really help.
