First thing you should do is source the genetics. If you don't have access to top-quality clones, buy regular seeds, veg them, clone them, grow out the clones (cloning them again for possible mothers) and pick a couple keepers. Shouldn't take more than 6 months to have keeper mothers that'll give you all the clones you can handle.

Then look into vertical lighting - hanging 1000w bulbs so that you don't need reflectors and use all 360 degrees of the lights.
