i wouldnt have reccomended this as it is actually murder.. depriving it o2 wouldnt really do anything at all, it will just kill the roots. and the plant will have sucked up an ass of moisture before the chop.
the reason we use the dark cycle or harvest during lights off is because this is supposedly when the plant has sent all the nutes back into the roots and go to sleep(have u ever noticed plants at night, and no i dont really mean "sleep").
i would much rather let my plant dry out rather than be flooded when im ready to harvest.
