grow tomatoes in a continuous flow of solution?

Can you grow tomatoes in a continuous flow of solution? Our school has such a system, the pump pumps the solution into the upper end and the solution flows down the pipe into a tank. If so can you start the seeds in this system using a type of sponge block?

The system is called NFT and you use rockwool cubes to start your seeds.
