obviously it is extremly hard to tell a plant is pure female,we should never use this terms,unless you went through 100 test natural and non natural as sts ,coloidal ,silver aspirin ,any plant can reversed with a ph 3 for 15 days, roots damages ,photoperiod changes,hormones,sytokinines,etc...unless one says I went through doing 50 test indoor outdoor and this plant never reversed....but all plants can reversed ALL.....if they are pushed to....it is also why we have cannabis nowdays so they could self pollinated herself....saying it is a pure female is a big lie....
to produce fem seeds you need to find a plant that has a high level of being triggered that won't reversed so easily but obviously all plant reversed with sts,or other tricks,so for me pure female never existed....it does not mean our female plant (reg or feminised) are not true female but it means they can reversed a way or another ,in your enviroment or in someone else garden with someone else tricks.
Or at least the guy saying this plant is a pure female should add,I never seen it reversed under classic natural outdoor or and indoor condition but it does not mean the plant will not reversed with a treatment...so ....and you will agree his own test indoor and outdoor regards himself as another grower may reversed this plant with other natural condition...so it is all bullshit....
