If you have 2 pots, and germinate 20 seeds, you DO increase your chances of getting 2 females. No one is saying that this is concrete. Statistics is not fact, its an educated guess. People in statistics never say, theres a 70% chance for rain. They would say, there is a 60-80% chance of rain. Thus, allowing them a better chance of being correct.

If you were to bet me I couldn't flip a coin heads 2 times, I would ask how many times I get to flip the coin, if you give me 2 times and I want 20 times, I have a better chance of flipping heads when the coin is flipped 20 times then only 2. Like you said, if every seed has a 50% chance of being male/female. The more chances you give the crop to BE female the better the chance you will get your desired outcome.

In this case, you'd be running 20 different experiments. All at 50%. If I only ran 2 experiments, I'd hate my odds. If I ran 20, I'd take those any day.

And feminized seeds will of course increase your chances, but no one is arguing that point.
Balkey Reviewed by Balkey on . decrease the chance of having all males using math Let's say you've got a small grow space and can only flower two plants. So you plant 3 seedlings instead of 2 hoping to increase your chances of having 2 females. Common sense, right? But by how much exactly did you increase your chances? If you only have 2 seedlings, assuming you don't have feminized seeds and ignoring environmental factors which might affect sex, you've only got a 1-in-4 chance (25%) that both are female. But there's also a 1-in-4 chance that both are males. There's a Rating: 5
