do you have a 1/4" drill bit?  If so, space the holes every 2" on all 6 sides.

I would try to get one; a 1/2" hole has four times the area of a 1/4" hole.

That drill bit makes a hole that is 4x larger than a 1/4" {pi(2r)^2/pi(r)^2 = 4:1}, so maybe 1 hole per 4 times as much area, so space them out every 4 inches (to quadruple the area, double the side of a square)?

It may work or it may not work. 1/4" has been tried and tested to work, so that would be best. You could always drill the holes and then tape them so only a quarter is exposed, but that would be a huge pain.

Besides, 1/2" holes on the bottom may make it difficult to pour perlite on top.
