i would say hydro would be your best bet, its going to take a great amount of light to aim for your goal, i would say 2 600watt hps lights if your a really good grower or 2x1000watt hps lights otherwise.

you need atleast 50-60 days of flower to reach this goal so every 30 days isnt possible, your going to need a good amount of clones as well but i never grew clones so this isnt my area.

your space is good and you need to think of how to vent all this heat and stink this will create.
