Cannabis growers, whether seasoned or newbies, often encounter a perplexing challenge: bisexual cannabis plants, also known as hermaphrodites or “hermies.” While the cannabis cultivation journey is rewarding, this specific trait can spell trouble if left unchecked. Let’s dive into what makes hermaphroditic cannabis plants a concern and how to manage them effectively.
What Causes Cannabis to Go Hermaphrodite?
The hermaphrodite (or “herme”) trait in cannabis plants usually emerges as a stress response. Factors like light leaks, nutrient imbalances, or irregular watering schedules can push even robust strains toward this unwanted state. While any cannabis plant can develop hermaphrodite tendencies under stress, certain strains have a genetic predisposition. This is particularly true for feminized seeds, which are purposefully bred to produce female plants but may inadvertently carry hermaphrodite traits.
One key takeaway for growers is to avoid breeding FEMINIZED.
strains with your own local male pollen. Doing so increases the risk of passing along these genetic quirks. Hermaphroditic plants are problematic because they can ruin an entire crop by producing seeds before you notice. The best defense is prevention through careful strain selection and controlled growing environments.
Spotting Hermaphrodite Traits in Cannabis
Not all male flowers in hermaphrodite plants look the same. The genetic hermaphrodite trait often produces a unique phenotype: tiny, banana-shaped male flowers tucked discreetly within female flower clusters. These flowers, colloquially known as “nanners,” are exceptionally hard to detect until it’s too late. When these nanners are covered in bright yellow pollen, they can quickly seed an entire crop, compromising both quality and yield.
Experienced growers emphasize the importance of regular plant inspections. If male flowers are spotted early, you can remove the affected plants before they pollinate others. However, catching these sneaky nanners requires vigilance and a trained eye, especially with genetically predisposed strains like
Hermaphroditism in cannabis plants is a hidden danger that can wreak havoc on your harvest. Understanding the causes, spotting the signs, and implementing preventive measures are vital for successful cultivation. By investing in stable genetics, maintaining a stress-free environment, and staying vigilant, you can minimize the risk of hermaphroditic plants and ensure a high-quality yield.
Stay proactive, and happy growing!
