NO, NO, NO!
Plants NEED sleep to finish their daily photosynthesis cycle and this allows them to have a correctly functioning metabolism.
A plant with an incorrectly functioning metabolism will never grow to its full potential.
24/0 could only be recommended by people who don't understand photosynthesis or uderstand how plants function either.
Everything on planet earth survives by having a circadian rhythm, without one, life is screwed.
18/6 is optimum.
