A photoperiod plant will not flower at 24/0.
If you want a decent smoke, give your plants what they need - sleep!
18/6 is optimum and a plant can not be healthy or function properly without a dark period during every 24 hour cycle.
Without sleep your plants will not be able to complete their photosynthesis cycle and have a correctly functioning metabolism and without a correctly functioning metabolism, your plants can not produce prime cannabinoids/trichomes.
Every living thing on planet Earth needs sleep, and cannabis is no exception!
By the way, photoperiod plant are superior to auto flowers in every respect in my opinion, so there is no reason why you can not obtain quality flowers from a photo period plant. Anyway, all auto flowering plants started out as photoperiod plants.
Hope this helps, Organoman.
