well,i sorta let this thred die huh?i have still been looking around and i think that i will cut down a little(6 600s seems more realistic,8000 watt gas generator converted to propane,running twelve hours a day rather than 24 so the 3 400s in veg will run off real electricity)should take about $10000,might be up and running this time next year.or maybe i am still dreaming
