Blue Mammoth Auto Feminised Seeds
I love this strain... It worked great!!!! It actually started turning purple black in the latter stages of growth and smells like fruity, skunky, coffee. Still curing but this stuff gets extreamly frosty during flowering. Would recomend it to anyone and will be growing more at some point

Great plant to grow, no mold issues, no bug issues either. I grew outdoors in a greenhouse, other bugs snuk in (grasshoppers, weevils) and went after some other strains but didnt nibble on my Blue Mammoth :)
