Blue dream

if it's a feminised plant you can make seeds by pollinisation it, or you can let it go longer until it hermies or try just increasing the light schedule until it gets stressed , but unless you're pollinizing it it's really a gamble. You can buy pollen online from some major seedbanks and seed brands direct, or just ask you fellow growers they might have some. your best bet might be just growing a male from regular seeds, takes not that long and if you have a seed from this one you can start it also , just put them in the same tent and it should work with no effort at all. good luck with that, hope this helps ! 🚀
