Shallow beds instead of NFT vs Aeroponics

[Fine Stuff]

Hello,
I have been testing a small NFT setup for a couple of months now and I want to start a greenhouse (8m x 30m) and I would like to know if it is possible to use shallow beds with foam boards instead of channels/pipes

I am thinking of putting 4 beds with 1.2m width in the greenhouse and the depth would be 5cm to 10 cm with shallow water running down the bed and back to the reservoir

I am planning on planting lettuce and sage.

I was originally going for the aeroponics but I will have a lot of mist sprinklers along the beds which should require a lot of maintenance.

I think Deep Water Culture will be the most expensive because the amount of water that will be used (It will require a lot of nutrients and will be harder to control).

What do you think?
