If you’re new to Homestead and Chill, be sure to check out our other cannabis-related articles! We primarily grow outdoors, 100% organic, and aim to provide helpful information that is easy to follow – both for new and experienced growers alike. As a disclaimer, this article is intended for those who can legally grow cannabis at home.

Another way to create feminized cannabis seeds is called rodelization. It is a more natural but unreliable method, and less frequently used by breeders. Near the end of a growing season, an un-pollinated female cannabis plant will sometimes produce pollen sacks in a desperate attempt to pollinate herself. That pollen can be used to try to create feminized seeds, but because ethylene hasn’t been repressed, may also result in male seeds.

Feminized vs Regular Cannabis Seeds

Are you growing cannabis at home, but aren’t sure if your plants are male or female? Then you’ve come to the right place! This article is going to show you how to tell the difference between male and female cannabis plants to properly sex them.

*Note that our feminized seedlings go from a 4” pot to an 8” pot, and then more quickly into large grow bags, using less soil in the potting-up process.

In contrast, the very early female cannabis pre-flowers are more ovate in shape: pear-like, but with a longer slender pointed tip. That is called her calyx. Extending from the tip of the calyx may be a pair of pistils, or white hair-like protrusions. However, please note that not every female cannabis plant in pre-flower produces pistils.

For those who don’t use feminized seeds, being able to tell the sex of a cannabis seed by looking at it would be a pretty handy skill. But is it possible?

Even feminized seed, which have been bred to have 99.9% chance of growing female, can turn into male or hermaphrodite plants if put under a ton of stress while growing. This is very rarely a worry for feminized growers, as they don’t tend to stress out their plants to this extreme extent – but it is possible.

DETERMINING THE SEX OF YOUR CANNABIS BEFORE IT COMES A PROBLEM

If you are a veteran of the cannabis community, or spent a lot of your time reading up on cannabis, you may have heard that it is possible to tell the sex of cannabis seed simply from its appearance. There is even a chart floating about out there that describes the physical differences between male and female seeds.

While being able to determine the sex of a cannabis seed by looking at it is a myth, being able to sex your cannabis early isn’t.

If you don’t want to take the risk, then sexing your cannabis early is pretty easy, and stress-free. It basically involves placing a black bag over a small section of the plant during the vegetative stage to force pre-flowering, before allowing it to revert back. This gives you a clear idea of what sex your plants are, without undue worry, wasted time, or effort.
