Dry cell design?

[gmcain09]

Hey guys, I was thinking about using 2 1/2" x 6", should I try to do a square 4x4 or does shape not matter??

Mike,
4x4 will work, but it all depends on how many cells you're talking about and how much hydroxy you want to produce.
Lots of people are going towards tall and narrow with great results. You need to do a bunch of research before you start to build.
