give em a go, bag seed is the best way to start...especially if you're new to growing. If they're male... well, shit.. that'd suck. It's unlikely to happen, if the seeds look good and are reasonable in size then chance are out of 20 you'll get at least one female. And if you don't, well.. male plants grow to.. if you can grow a male plant really well, you can grow a female plant just as well

give her a go, post some pics. keep us updated..

Enjoy!
