yes ,if you want to get max professional results, go with 600 watt hps systems, you get more lumuns per watt consumption,, 4 six hundred hps will do for budding these many plants if you keep them at a smallish size , , You can realisticly obtain 2 oz per plant, this will vary,, personally i would go with a few less plants and shoot for 3 or4 oz per, when you get more grow time experience you will obtain better results, anyway, go with 600 watt systems unless u get an extrmrly good deal on the 1 k lights, and this is not to mention the vegging arrangement...oh i forgot to say that if your hydro guy hasnt told u this u cant trust him...dont buy his 1k systems he cant sell to anyone else...the 6oo hps is a known superior light to the 1000k systems...more light for power consumed..
