Is this male or female?

Well, there are no signs on the plant, but judging by the hairbrush, i'm saying female. I can see you are a bit worried from the multiple questions. if it's an 'autoflower' or a feminized seed, it is female. If it's a seed you got from a bag... still most likely female, but potential of a male rises. bagseed comes from accidental herms more than contamination from a male plant, i'd wager. Relax. There is an absolute shit-ton of time to identify a male plant before it can do anything harmful beyond wasting a few weeks of your time. go read guides on cocoforcannabis.com. check out bruce bugbee / apogee instruments on youtube... best thing to do with plants is stay out of their way.

To early to tell, female white hairs will be a little longer than an eye lash but curly and wavy. They will also be a brilliant white color. Male plants will show little banana looking things, yellow in color. Once your plant starts to show it's sex, there will be no mistaking it. If this is an auto flower plant, the plant will reveal its sex somewhere around 3-5 weeks after germination(genetics depending) If this is a photoperiod plant, then it won't reveal it's sex until the light rhythm changes to 12hours on/ 12 hours off.
