i would call that an educated opinion/theory based on facts/science.. i like it but i think its still up to debate until a massive class action trial happens and someone can show us with proof that the ratio of males to females grown with the exact strain in the exact conditions is higher for 24 hour light than 18/6. to ensure any faults in probability i think you would need a volume of at least 50 to 100 plants for each different light cycle. I think until such an experiment is undertaken there will be constant bitching over growers who have been doing it the way they have been doing it for years and standing up for it by finding other biased opinions.
