IF you found some hermis, chances are that you will find the same level of hermaphrotidism in any offspring of that breeding.
Allow at least 3 weeks between pollenation and harvest.
When you harvest, trim up your buds normally, but when you hang them, do it over a tub or tray to catch any seeds that fall out during the drying process.
