TBH personally i wouldn't set your self up for disaster start of with 6 k get it going then add lights if need be some people think that adding more power will indeed up your game when truth is in most cases GPW drops , just saying
Your in a new area get the feel of the climate and what will come at you , then slowly go bigger,, unexpected things
We see it all the time leave your self room to spread out throwing all your eggs in one room is looking for trouble , like people crying when they put all there plants in one out door spot only to find it ribbened up or stolen
get cuts that are 100 percent insect and disease free would hate to be runnning 24 k litterally 24 hrs a day 600 plants or what ever only to have insects. or disease wipe out your first grow now your stuck with rent , power usage, and nutrient bills
thats the problem today people jump to hard into the puddle rather then take gradual steps
Just my thought tho good luck
