How to Predetermine the Sex of Cannabis Plants | Colorado Pot Guide


Female cannabis plants are the only ones that create flowers. Male cannabis plants create pollen which, if exposed to female cannabis plants, will outcome in seedy weed. Consequently, to cultivate seedless cannabis buds (a.k.a. “sinsemilla”), you ought to eliminate all males from a develop atmosphere just before pollen sacks kind. To do so, you ought to identify a plant’s sex just before 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). Currently, we’ll clarify how to identify the sex of your cannabis plants just before they have a likelihood to either pollinate or grow to be pollinated. 

Why Sex Cannabis Plants?

As talked about, male cannabis plants create pollen which can conveniently spread all through a develop region. In reality, a single male plant can pollinate hundreds of females inside a single develop space! To make matters worse, male cannabis plants create pollen sacks just before females start generating buds. It frequently requires about 1 to two weeks for male plants to start generating pollen sacks (characterized by a tiny “sack” as opposed to a white “hair” or pistil) whereas female plants frequently take two to 4 weeks or longer to show gender.

Although genetically speaking, this is a fantastic way for plants to make sure reproduction, contemporary develop procedures advise against this. Soon after all, as soon as a male cannabis plant drops pollen, any nearby females will create seeds in response. This not only increases weight, but it also reduces potency and adds 1 added step to the smoking approach. 

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. Particularly, you can “force sex” a plant to identify its gender just before flowering the entire issue. 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 whether 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 particular 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 issues to appear out for which may well assistance you identify the sex of your cannabis plant involve the plant’s height (males have a tendency to be taller than females although a great deal of this depends on the strain sort, as effectively) and the size of the calyx, or the center-most element of a flower. If the calyx is huge with a protruding white hair, it is most likely female. On the other hand, if tiny and swollen with no hair, it is most likely a male. This distinction can be created just before the plant starts flowering for the duration of a stage known as “pre-flower.” Having said that, it can be tough for the naked eye to identify gender at this stage a jeweler’s magnifying glass can assistance, although.

Knowledgeable cannabis growers recognize the significance of separating male from female cannabis plants. With a tiny practice, lots of can catch and dispose of males lengthy just before they have the likelihood to pollinate females. Luckily, even if you are just beginning the homegrown cultivation approach, you can sex your plants just before it is as well late, as effectively.
