how do you tell the difference between male & female seeds. Do seed producers pick through a batch of seeds or do the plants produce only fem seeds at a certain time in the grow period
Yup to true, you gotta analyze the DNA to find out, lol jk. Theres a sticky for you. http://forum.grasscity.com/absolute-beginners/101130-sexing.html
Well there are a few ways, you lick the seed a little. If it tastes like lemons, it's a female, if it tastes more like a sweet citrus, it's a male. Also, if you take a stethoscope and listen to the seed, females make little clicking noises and males make more of a thumping noise. One last thing, if you grow your seed and it forms flowers, it's a female, if it has pollen sacs, it's a male.
You cannot tell gender by the seed's appearance, you have to grow them out to sexual maturity to tell. Breeders use cross-breeding techniques, hormones, and stress plants in special ways to induce females to produce pollen sacs, that pollen is 100% feminized, then they use that to pollinate another female to produce the feminized seeds you may have heard about.
