no one here is going to start from scratch and design a grow room for you. instead, do some reading, come up with a preliminary plan and then we can help you refine it. check out the links in my signature below for some great posts for newbies. at the end of the day you'll want two grow rooms, one for vegging and one for flowering, with plants of different ages in each room to produce a regular weekly or bi-weekly harvest. plan on starting with just a couple of plants to debug both your grow skills and the room. come back with more specific questions and i'll be happy to help.
