Since I haven't messed with them in about a year my memory may be a bit fuzzy, but IIRC. I ended up using cut to size insulation Styrofoam [1/2 inch thick 4' by 8'] as the separator and septic tank drainage pipe [with holes type] to hold the wick and hold up the Styrofoam. I used a jig saw to do all the cutting and I don't remember what size drill I used to do the holes in the separator.

I found this to be the easiest way to do it. I used the large RubberMaid containers, a good bit larger than the bought EBs; holds more water and soil. To, I drilled two holes half way up container on each side and used telephone type rubberized wire to keep sides from expanding.

The two early tomatoes I grew in one container did rather well, as did most all the stuff I grew in the other ones; herbs, lettuce and etc.
