i was under the impression that they would be much more developed in almost 3 months as they are supposed to be flowering pretty much from the beginning with no need for light change but i dont know as i dont use any auto flowers
usually a 50 50 boy girl split sometimes more boys sometimes more girls but when u get a pack of 6 or 10 beans should be able to gender at least a couple girls
yes can be done but higer chance of herming and less potency due to the chromosone change but yea its not really a problem to gender it can be done in veg in apx 4 -6 weeks willshow signs of gender
