Yep...good stuff!
I have that kind of systems going on but they are commercially made.
You can also do it 'plant pot on top of bucket' method....either having lidded bucket and cutting hole on the lid or with piece of compost bag/bin liner and instead of bamboo canes supporting the weight of the pot and plant..standing two bricks upright, having gap between each and plant pot sitting on the bricks.
They all work really well as long as the light is cut out from the water holding area..
Go for it girl!
