Sounds like a good plan. I was going to do a similar op, using 600 watt digital cool tubed HPS for a 4'x4' flowering area rotating with a clone box and a veg cabinet and doing the SoG method. I read Al B Fuct's rotating harvest threads, and I'm just amazed. If you could rotate a good number of plants in trays every two weeks or once a month only growing colas, I think that would be most efficient in terms of productivity. Of course a monster SCROG/LST would be cool also, but the idea of rotating and keeping crops fresh is what turns me onto the SoG method.
