How To Identify Male and Female Cannabis Flowers
Professor DeBacco
Pre-Flowers
Growers should first look at the nodes (junction of leaves/branches and the stalks of the plant).
Pre-flowers begin to develop 4-6 weeks into the growing cycle at the nodes and during this time growers should be able to identify the gender of the plant as male or female.
These are immature flowers and will show the male or female morphology well before they are able to produce viable components for seed production.
Removing males at this time will help ensure no chance of accidental pollination will occur.
Male pre-flowers: Look for small pollen sacs
Female pre-flowers: Look for two stigmas (typically white)
Female Plants
Females are the plants that will produce the cannabinoids in the greatest concentrations in the flowers.
If female plants receive pollen from male plants seeds will be produced which will drastically reduce cannabinoid production.
Cannabis is grown via sinsemilla (“seedless”) by removing male pollen producing plants to prevent seed production.
This allows for the cannabis plant to focus its energy on cannabinoid production instead of seeds.
Female plants will only be pollinated to produce seeds for breeding purposes.
Male Plants
Male cannabis plants grow pollen sacs instead of buds and are often discarded to avoid female plants from being pollinated.
Males are important in the breeding process
Pollinating male plants shape, rate of growth, pest and mold resistance, and climate resilience can important for breeding purposes.
Male plants can also be used for:
Hemp fiber and in some cases concentrate production but concentration is much less than female plants.

Hallo ,correctly is sensimilla not sinsemilla
Thanks a lot 🙏
Very clear explanation
It’s just basic and when it start showing pollen it’s too late for outdoor. Any method for early stage sign?
When is the optimal week of flower for pollination? & how long until to seeds are mature? Do you need to extend your flowering time? Thanks in advance!
Professor is such a low title when it comes to what you give us as a teacher of cannabis
Great video thanks! Once there are signs of preflower you switch the light cycle to flowering? Or let them stay in the vegetative stage longer?
🤓add some music and explosion…… thank you for the information.
these videos are awesome…..saves on guess work…!!!!!!!!!
Great educational video thank you.
💞
Great info, thanks
You mentioned being able to identify Male and female plants at the 4-6 week mark.. I assumed this is in Veg? I normally veg my plants about 7 weeks (27-30”) before flower. I assume there is no threat to the female plants until I flip them to flower? I also wanted to confirm the males can be identified before flipping to flower.. thanks
Do male plants produce only male seeds
I have both, did I screw up my first plants?
sin semillas is Spanish for without seeds
Is there any way I can help your university?
Pardon me but I’m writing this just to say thank you this information is straight up and informational just what I needed thanks peace
