ok, this is gunna be my first time building a box, followed by my first grow. my box is gunna have to be kind of ghetto, but that's ok. i'm just going to attempt to grow one plant as a learning experience. then after i learn some i'll upgrade my grow box and maybe attempt more than one plant. this is a little shelve area on my computer desk. i plan on putting some plywood in the back that i'll equip with a computer fan exhaust (running on a 9v converter). then i'll build a cabinet door on hinges for the front, doing my best to make it so no light escapes. i'm on a serious budget here. the area i have to work with is 27.5" tall X 18" wide X 18.5" deep. it's got two removable/adjustable shelves. i figure those might come in handy.
my first question is what kind of light(s) should i use? keep in mind i'm only planning on growing one plant and i can adjust the shelves so it's always close to the light.
my second question: will one computer fan running on a 9V converter create enough airflow if i drill a couple air inlets (fitted with pvc elbow joints painted black on the inside and covered with a fine screen to keep unwanted critters out)? i'm sure i'll have more questions, i just wanted to get started off right and with the help of you pros
