male/female ratio; beginners luck?

Hi. I'm on my second grow. On my first I started 3 from bagseed and got 2 females. This time I started 2 from bagseed and got 2 females. That's 80% females so far. Have I just been lucky or does it mean I'm providing an environment that's conducive to getting females?

There seems to still be a debate over whether sex is entirely genetically predetermined or if environment plays a factor. What do you think?

The sample size is too small to say the ratio means anything at this point.

luck

Bagseed can often be the result of hermies. Most of the time if I plant bagseed I assume it will be female for that reason.
