Female cannabis plants are the only ones that make flowers. Male cannabis plants make pollen which, if exposed to female cannabis plants, will outcome in seedy weed. As a result, to cultivate seedless cannabis buds (a.k.a. “sinsemilla”), you ought to eliminate all males from a develop atmosphere prior to pollen sacks type. To do so, you ought to identify a plant’s sex prior to they transition from veg to flower. Although most cloned cannabis plants will be female, cannabis grown from seed could be either/or (unless developing feminized seeds, that is). Right now, we’ll clarify how to identify the sex of your cannabis plants prior to they have a likelihood to either pollinate or turn into pollinated. 

Why Sex Cannabis Plants?

As pointed out, male cannabis plants make pollen which can effortlessly spread all through a develop location. In truth, a single male plant can pollinate hundreds of females inside a single develop space! To make matters worse, male cannabis plants create pollen sacks prior to females start creating buds. It generally requires about a single to two weeks for male plants to start creating pollen sacks (characterized by a modest “sack” as opposed to a white “hair” or pistil) whereas female plants generally take two to 4 weeks or longer to show gender.

Although genetically speaking, this is a good way for plants to make sure reproduction, modern day develop approaches advise against this. Immediately after all, as soon as a male cannabis plant drops pollen, any nearby females will make seeds in response. This not only increases weight, but it also reduces potency and adds a single further step to the smoking method. 

Methods for Sexing Your Cannabis Plants

There is an simpler way to identify the sex of cannabis plants than to just watch, wait, and hope it is not as well late. Especially, you can “force sex” a plant to identify its gender prior to flowering the complete point. To force sex a cannabis plant, just spot its clone in a 12/12 light cycle (12 hours of light/12 hours of full darkness). This photoperiod manipulation signals to the plant that it is time to start out flowering no matter if the plant currently has roots or not.

Mainly because clones are precise genetic copies of their parents, forcing a clone to flower separate from its parent will give you a clue with regards to the certain gender of its parent.

If a clone produces pollen, you know its parent is a male. Conversely, if the clone starts to flower (appear for these pistils), you know its parent is female. Now you can eliminate all male parents leaving only the females behind to flower. No pollen, no seeds, only content girls and bountiful buds.

Other factors to appear out for which may possibly support you identify the sex of your cannabis plant contain the plant’s height (males have a tendency to be taller than females even though a great deal of this depends on the strain kind, as effectively) and the size of the calyx, or the center-most portion of a flower. If the calyx is massive with a protruding white hair, it is probably female. On the other hand, if modest and swollen with no hair, it is probably a male. This distinction can be produced prior to the plant starts flowering throughout a stage known as “pre-flower.” Even so, it can be challenging for the naked eye to identify gender at this stage a jeweler’s magnifying glass can support, even though.

Male Plant

Knowledgeable cannabis growers have an understanding of the value of separating male from female cannabis plants. With a tiny practice, numerous can catch and dispose of males extended prior to they have the likelihood to pollinate females. Thankfully, even if you are just beginning the homegrown cultivation method, you can sex your plants prior to it is as well late, as effectively. Use these guidelines to predetermine the sex of your cannabis plants so that your girls will thrive unadulterated.
