sativa generally is harder do grow, and takes more time
don't waste time wth FCLs, especially for scrog, get an HPS light, it is more efficient, with a 250W HPS you will get better result than with 400W of CFL lights
you will also need a cool tube type of reflector, cuz you are kind of limited in height and without a cooled reflector there is a chance the for the light to burn your plants
other possibility is making a T5 setup, you will still get more light per watt compared to CFLs, but nothing beats the HPS, if you want serious buds you simply need HPS
my suggestion is to make 1 or 2 mother plants and a cloner (you'll need another growing space for the mothers), you have to put clones in flower as soon as they make some roots, you can start preparing the clones a weak before harvest so you can immediately put new clones in flower as soon as your first crop is ready
