well my opinion. if you wanna make it big then.If you are only growing one plant. I would find an area that you have ceiling space like 6-7 ft. Then i would purchase a ten gallon container.enclose the the contaniner with mylar or a flat white material.You will wanna fill the container with plain poting soil.this will allow the roots plenty of room to dig.For light i would use a 250hps. fan ,well for a space that small might get warm.either exhuast fan if the area is a closet .or a simple household fan will do. feed it every other watering starting mild then increase into flowering. stop fert. several weeks before harvest and then just use plain water to flush soil. With an area that small ,with that much light on one plant ,that has abundent soil to roam.you should get a big plant. ok i would start out with 18/6 for atleast 2 month. then give her 12/12.After 4 weeks of 12/12 decrease you daylight time by15 min. a week.(you will need a timer for this). these are just some note i have kept on a grow i did this and had great results. good luck
