I'd definitely get some Jack Herer from Sensi Seeds. You'll end up with a couple of different phenos that are awsome. I have 3 different phenos for mothers and i love them all. Completely different smell and growth pattern.
If you like som good indica i would get a Black Domina from sensi as well - very potent indica.
As you know there are thousands of strains. Jack is my favorite so far.
Get some white russian, very potent plant.. deff pick up some kush because it still contains one the highest THC % out of indica and who doesn't love taking one hit and being glued to your seat.
get cheese, ak47 serious, white russian, if you can find mr nice's black widow, medicine man good luck with that though. yeah a must grow experience for super lemon haze.
