Hi HemperFi,
pollination is a very straight forward process and works
so well that your main problem is separating the pollen source from your target females as pollen is microscopically small, it's like talc in consistency and is so fine it can be carried on air currents so try to have as much distance between them and
don't have circulating fans running in the male room as they will blast all the pollen into the surrounding air and cause contamination for sure.
When a male starts to shed pollen I often bend it over and put a large clean sheet under the plant and tap gently and then the pollen falls onto the sheet and can be scraped into a pile and cleaned and stored for later use.
You
must clean the pollen of any plant matter as male flowers are fragile and bits of them will be in the dust.
If you scrape a fine hair comb through the pollen it will pull most of the green matter out and use tweezers to remove anything remaining. This is essential as any plant matter left will add moisture to the pollen and be a possible mold problem.
When you have your pollen take a desired female and if pollinating only one branch it helps to put a plastic bag over the plant, make a hole in the bag and pull the branch to be pollinated through and seal with tape. It doesn't have to be 100% airtight but it will largely prevent contamination.
Dust the branch by applying by brush or you can put an amount of pollen on a sheet of paper, hold near branch and blow sharply and this will pepper the branch with love bullets nicely! :hubba:
Just put small amounts on the paper and do this several times from different angles. If you see the pic, this is a grow from a while back where I bagged the top cola's to protect them as I wanted them for evaluation purposes whereas the rest of the room was being subjected to a total pollen blizzard.
Once pollinated, leave for an hour although it actually only takes minutes for successful pollination to occur but that extra time will let all airborne pollen land and then spray thoroughly, allow to dry for a few hours and place back under your lights, job done.
The bath can be a good place to do it as you can wash it down easily and kill any remaining loose pollen.
I hope this helps and do please remember, no circ fans in the male room.
