If you get a nice 24" tube fluoros then you can lay the box sideways and fit alot more clones in it.. if you stand it up then you can grow them taller but you wont fit as many.. I can fit around 3-5 clones per cup and I can fit 5 cups when the box is standing up. You should remove the subwoofer and midrange speaker and flip the box upside down so the big subwoofer hole is at the top and its alot easier to monitor the plants and remove or add them to the box.. I planned on adding light traps on the box for ventilation. I used black electrical tape and some cardboard to make a ghetto door for it.. pics coming soon
