perpetual room idea

okay 3-4x8 tables with sunshine 4,one table in veg room under 2 400watt mh,first table in flower under 2-600 watt hps,second table in flower under 2 1000 hps,every 4 weeks moving another table down the line,clones from table 1 5-7 days in flower take clones while cleaning up bottoms then when rooted start vegging,one week of veg being 6-8 inches tall and flower away.does the light seem to weak or will it be okay,flower tables will be side by side working or sharing eachothers light...?thoughts? thanxs
