Cannabis Hermaphrodites, Stress Testing
Cannabis Hermaphrodites are no fun to work with and could seed your whole crop.
The goal of a cannabis pheno hunt isn’t just to find plants with outstanding qualities it is also to find sexually stable phenotypes. Therefore, stress testing is one of the most important parts of every successful pheno hunt. Whether you are a commercial growers, a hobby grower or a breeder, working with pure, sexually stable females will turn out to be crucial.
In this tutorial we’ll first debunk some of the myths surrounding cannabis hermaphrodites. Then we will go over some useful tips on how you could effectively stress test your cannabis plants.
I Cannabis Hermaphrodite Myths
Myth 1: Feminized Cannabis Plants Aren't As Sexually Stable As Regular Cannabis Plants
Myth 2: Cannabis Hermaphrodites Are Rare And Most Cannabis Plants Are Sexually Stable
Myth 3: Hermaphroditism Is Due To Stressful Growing Conditions
No matter how skilled you are at tending your garden you are always at risk of having some of your plants herm. This is because hermaphroditism is already present within the plant’s DNA. Although stressful conditions cause most plants to reveal their intersex tendencies, highly sexually stable plants will not herm even when under stress.
Myth 4: Landraces And Wild Cannabis Varieties Do Not Herm As Much As Modern Strains
It is quite the opposite. For many landraces and wild plants, having the ability to turn hermaphrodite is a survival mechanism. It allows the plants to reproduce even when there are no males or females around.
As hermaphroditism is an undesirable trait, many modern breeders have helped increase the sexual stability of most modern cannabis strains.
II Stress Testing Tips
Here are 7 simple tips you can easily apply in order to force your plants to reveal their hermaphroditic tendencies:
1. Grow Your Plants Indoors
Outdoor plants almost never show their hermaphroditic tendencies. However the same plants grown indoors could easily grow some “nanners” or “ball sacs”.
That is because indoors, the light spectrum isn’t the same as the sun’s. Likewise the root ball of the plants is at room temperature whereas outdoors, it is often cooler than the air. The light cycle and the soil composition are also different. All these factors cause a lot of stress to the plants thus explaining why plants herm much ore often indoors.
2. Use Small Containers For The Entire Life Cycle
3. Raise The Temperature Of Your Grow Room
4. Give Your Cannabis Plants Too Much Nitrogen
5. Over/Under Water Your Plants
6. Let Your Cannabis Finish Under 24 Hours Of Daily Light
7. Let The Plants Flower Past The Harvest Date
