I moved into a new apartment, and finally have space to grow my own personal stash now. I have done a ton of research on growing indoors, but I still feel like it would be a good idea to go out and consult the professionals before making any purchases. Anyway, my space is a closet, which is about 2.5 feet wide, 2 feet deep, and around 14 feet tall (its a huge guy). My plan was to put it 5-6 plants, and allow them to reach insane heights because of the available space. Is that possible? And if so, what kinds of lights and exhaust system should I be looking for?
