I have a NFT / Ebb system. The plants at the end of my pipe are near the drain. I know the roots are going to go into the drain and possibly plug the drain. This is the nft drain. The over flow drain for the ebb partis higher and dry most of the time so that wont get root bound.

Is there anything that can prevent roots from growing into the drain?
