Fairly certain that’s a boy you have there. In regards to pollinating. will the females your pollinating be in pots or planted in ground? If they are in pots and mobile I would bring the plant inside somewhere where there is no air movement at all. Or you could bag the branches with a ziplock or any kind of bag to prevent them from getting wet. Spray everything everywhere in your greenhouse and plants to mitigate stray pollen. When you have sprayed them down welll carefully remove the bags trying to keep all moisture off the buds you had bagged. Then take a little paint brush or cue tip and apply the pollen to the buds. Making sure to pollinate when there is plenty of white hairs around week 3-4 depending on the strain. Hope this helps.
