In the wild, the ratio is pretty close to 5:1. In captivity, I'd hazard a guess of 20:1. It is much, MUCH higher in captivity. Don't you ever wonder why there are small, medium, and large plants simultaneously available from TC? They're grown out for a reason, and I think it would be complete rubbish to call it coincidence that such a staggering number just "happen" to be male.
