Hydo balls do absorb moisture, and u can mix gravel, make sure u have a PVC pipe with cap, so u can access to drain water when u need to. I've also heard of people just using syrofoam packing peanuts, so maybe some of that at base. U can use a turkey baister to drain excess water. So PVC can total be hidden and short.
