Hello
@Boxgrower ! Here is what i do. At around 5 weeks of flowering when the sacs are starting to open and release pollen, i take a paper bug, i put the male buds inside one by one without cut them and i just shake them. All the pollen with some mature sacks are falling inside the paper bag. I repeat this process every three days.I use the paper bags instead of plastic re-saleable bags because of luck of static electricity. When you use plastic bags the pollen is attracted on the plastic and you have a big loss. Happy growing ! 👊
