It all depends on how you design it and set it up. You can run a NFT system with little to no
growing medium. Depending on what you grow, it may need additional support that you can provide from above. Though the use of a growing medium can provide more moisture to the main root ball. The roots actually wick up the
nutrients in an NFT system, but as they do, the growing medium (if used) will be able to hold some moisture as well. In either case until the roots are long enough to reach the water supply, they wont wick up anything. So you will need to adjust the water level accordingly as they grow.
