I agree with you, I think that WOULD make more corraloid roots. I tried some grow bags a few years ago and had very small holes that let in a little light, and also had some air movement and the corraloid roots lined the outside edge. For you, the regular roots might stay in the middle of the pot and the corraloid roots would grow towards the outside of the pots to suck up some sun.
