hi all, i have found that muterlating a plant can do this , ( overtriming ) i know what you say about if its gonna be a hermie then its gonna be one and that is true, however during my early grow days i did hundreds of various experiments including trimming to force flower increase, these were not just random experiments but calculated and logged over a long time, i can say with a modest amount of knowledge that i did produce plants that showed hermie features from mothers that were know to be relible female stock, i also found that certain deseases can premote male gender on an otherwise reliable female, as for light altering a plants gender i cant say with any certainty but i do suspect it may happen, , i have had quality girls that have had shown male gender when my lights have gone up the wall, if you can bring male gender to a female plant by trimming, desease, heavy and feed starvation cycles, and by simply spraying with a certain sollution, then it may well do this under light stress, well thats what i think, i hope i aint rattled anyone but i just felt that i could say what i know, all the best to all of ya, i will be sitting here should you wish to reply
