In this week’s PotCast episode, we take a look at what happens when a cannabis plant hermaphrodites and how you take steps to prevent it from doing so. To follow up this initial topic, we take a look at how you differentiate banners from a true hermaphrodite cannabis plant.

How to Prevent Hermaphrodite Cannabis Plants

Hermaphrodites or hermies are what we call the situation your cannabis plants may find themselves in when they start to display traits of female and male cannabis plants.

Hermaphroditism is a serious issue faced by many cannabis cultivators. It can be caused by a number of problems, from the genetics of the seeds you are growing from or the environment you’re growing the plant in, as well as a number of other factors. A cannabis plant turning hermaphrodite can seriously harm your crops, they can potentially pollinate all of the female plants in your grow room and essentially leave you with nothing but seeds.

Ok, so let’s look at one way that may cause your cannabis plants to turn hermaphrodite.

Light leaks can be a huge problem in general and also one of the most common causes of hermaphroditism. If you are growing photoperiod plants and not autoflowering seeds, then it is important to ensure that they get proper light cycles, whether you are growing indoors or outdoors. Even the smallest light leak can be enough to cause some genetics to develop male parts, so you must ensure to keep areas dark during the dark periods. A way to combat this is to make sure you’re buying top quality tents.

True Hermaphrodite vs Nanners

How do you differentiate between hermaphrodites and nanners? Luckily, Kronic is on hand to help you out and give you some tips to tell the difference between these similar, but nonetheless unfortunate situations that you may find yourself in.

In cannabis you have XX plants and XY plants, as well as the variation of XY that can potentially have double chromosomes – these are what we would call hermaphrodites. An XX plant is a genetic female plant with no issues, these would be like the plants which grow from feminized seeds, while XY plants would be the kind you may grow from regular seeds, which have a 50/50 chance of being male or female cannabis plants.

These variations of XY plants may potentially have double chromosomes, for example being XYY plants may result in an otherwise female plant displaying male traits, this means that at any point in its life the plant’s male hormones may kick as a self-preservation technique.

A nanner is similar to a true hermaphrodite, however, it is named after its shape, the shape of a banana. A nanner will begin to self-preserve due to stress by sprouting male pollen sacs.

But, there is much more to the issue than this, listen to our favorite PotCast host Kronic talk you through it, he’s an expert after all!
