You need to cover every square that they tower covers and every square the planter covers. They also need to be connected. I don't understand your 4 below the tower and 2 below the planter thing. I have one below the small planters and it works fine, 4 below large planters.

On that note, it also very much is not worth it. The increased yields do not get any where near justifying the cost in fertilizer.
