well... obviously if you buy a pack of seeds you should expect that around half are going to be male and half female. Unless you buy a pack of feminized seeds. If you don't want to spend alot of money, I would suggest you plant at least 3 seeds, grow them for a month or so, then clone them. Then flower the clones to see if the mothers are female. Most likely you will have at least one female, and then you can just take a bunch of clones off her. and you would have alot of females. By the way, you can't really turn them female.
