I forgot about this!!!!! I use smart pots (fabric pots) so this is not an issue, nor is the air flow to the roots... but yes I can see this in plastic pots for sure. These bugs are sneaky little bastards haha
I also be puttin the sand around the base of the plant in the drain catch to cover up these holes yu speak of. Glad yu be mentionin this very good point.
