I have another idea, I will stack my old 1 1/2 inch pool tubing in the middle of the bucket with 2 net cups on each side and fill the gaps with lava rock. The hollow tubing will hold more water in the reservoir.Like the idea about using the net pots....
But its not a big issue watering it once a day with the lava rock, since my pond is right next to my wicking buckets......................
