How to Counter Bias

Certainly there are already one or the other among the growers
asked why in the outing phase a rather mediocre to
has reached a miserable quota of women or has "sacks" at the
forming female plants.

I've made myself smart and I'm interested in a couple
and encountered important points that you should definitely know
before starting the first grow:

At what time do male flowers appear on female plants?

- At the beginning or middle of flowering. High risk for the rest of the garden: mostly pronounced hermaphrodites or hermaphrodites that transfer their hermaphroditic genes when fertilized.

- At the end of the flowering period. This is also a sign of maturity in otherwise all-female plants. Lots of indica and tropical strains
develop seeds when the plant has passed its flowering peak and is slowly dying.

What influences the development of hermaphrodites?

- Stress factors such as changed light cycles or light intensity, pest infestation, phytotoxic insecticides, lack of water, mutilation / severe cutting back, over- and under-fertilization, etc.

- Genetic engineering: Thai plants and other equatorial cannabis strains tend to be hermaphroditic.
Recessive genes that emerge under certain environmental factors.
Feminized strains that are not stable enough.

- A combination of low night temperature values, high humidity and increased nitrogen values.

Which factors favor the development of female plants?

- A basic pH of 6.6 - 6.8
- Good watering
- More nitrogen, less potassium
- Higher proportion of light from the blue spectrum (in the growth phase)
- Low stress such as pots that are too small, drought, heat, cut off shoots, pest infestation.
- Low temperatures.

What is there to do??

- All hermaphrodites and strong hermaphrodites must be removed immediately. These plants are also unsuitable for crossbreeding and contaminate the garden with pollen. Seeds that give rise to many hermaphrodites should be avoided the next time they are sown.

- Varieties that produce female and male plants very evenly are to be preferred. If there are a high number of female plants, the variety is more likely to be hermaphroditic and regular checks are required to ensure that no hermaphrodite goes undetected.

- Ripe plants that develop many male flowers should be harvested immediately !!
Male flowers leave an unpleasant taste and odor when smoked.

- No male flower is to be underestimated! It is said that not all of them are potent, but until now the opposite has been observed. Hermaphrodites first fertilize themselves and then their immediate surroundings. The inseminated plants quickly lose their psychoactive effect and flower development. This is why the "zero tolerance policy" applies (no pardon with it!). Sometimes removing isolated stems / male flowers with tweezers works (but only in a manageable garden) to get an otherwise good plant.
