I set up a 12"x16"x6 foot tall locker to start my plants for an outdoor grow. I bought 5 white cookie seeds but only want 4 outside so I was thinking of taking the shelves out of the locker and growing one in it. Will this work. I am only using one spiral daylight flourecent bulb which seems to light up the whole locker. I will also install a computer fan in one of the lockers vents blowing in. Can I make this work? If so is there anything else I'll need to do like topping to prevent it from growing into the light?
