With your given lighting you will not yeild an ounce per plant.... You will maybe get... 10 grams per... IF you really know what you are doing. I have seen people try to grow with shoplights and it simply doesn't work. The plants will stretch wildly out of control during the first month of flowering. If You plan on getting any kind of harvest then you'll need to invest in a few higher wattage CFLS (swirly,energy saver lights). They have the bluish white ones and yellowish orange ones. You want the big orange ones.
