The feminiser will not MAKE females. I thought this when I originally bought it but in actuality what it does is keep plants from becoming hermies due to stress. I am a huge believer in it.....my first grow (including my outdoor stuff) yielded 4 hermies out of 15 females....different kinds of seed as well--non of them purebred seeds. My hydro guy sold me this and I have not had a hermie since. 0 hermies in 11 females. Huge ratio difference in my book. All different seeds. And while I always swear to myself to reduce my plants stress.....I have not been able to accomplish that yet.....I keep finding SOMETHING to stress my plants out.
What about singing to your plant? Just a thought.

I'm new to this forum..can you post me a link that would be considered the definitive guide to distinguishing between male and female plants as early as possible?
