I would think roots would grow right through pantyhose or fishnet easily since it can grow through rockwool or even coco real easily. probably would plug it faster since now instead of one drain hole you got thousands that can easily be pluged by your roots
cigarettes42 Reviewed by cigarettes42 on . NFT / Ebb Drainage problems 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? Rating: 5
