Seriously, consider the tanks that are immersion started. So far as I know, they don't dose anything except good old fashioned water to keep 'em wet.
Who is chuck? Chuck Norris?lol
Yes you add ferts to emersed setups unless
you have a nutrient rich substrate
you can mist the plants if you use flourite black etc with a NPK and trace solution 2x a week otherwise
You cannot grow plants w/o nutrients, its not possible. That's like driving an internal combustion engine automobile w/o fuel, not happening
