vegging 24/7 is fine especially if everything is in good swing and on point, i think half of us do, i always do it that way unless something is going amiss and i might give them a break. i notice that stressed plants benefit from rest, for sure. ive read in a few places that anything more than 20 hrs of light per "day" or cycle will not benefit in terms of faster growth, the plant simply cant do more than that, possibly is the explanation. ive also read that plants are very responsive to circadian rhythms and will benefit from having some rest period. it makes sense that in nature they would do certain things at night, like we do in our sleep.
