>>1562529I am thinking on getting a somewhat big grow bag (150 Gal) then lining the bottom ~15cm with a pond liner. Use corrugated drainage pipe around the outside and sand in the middle to make the water reservoir. Put soil on top of that. The end product should be a flexible yet affordable self-wicking raised bed made out of a grow bag.

Purple is the pond liner.
1 fill tube
2 Water sitting on the corrugated drainage pipe that goes around the bottom of the bag.
3 saturated sand
4 wicking action of saturated sand
