10'x18' growroom

I have a 10x18 space to build my first growroom. Looking for any plans or advice that I can get. I was thinking of 3 - 6x10 rooms 1=veg,1=flower, 1=clone/utility but this plan can change.

Unless the walls are going to be 0" thick you may want to rethink size.

I can change what I do inside but the 10x18 is all I have to work with. Laws limit me to 6 plants in flower.

My thoughts were to have 2 - 6x10 rooms with 2 lamps per room
