My latest and maybe greatest is Humboldt Purple from Classic Seeds. Great buzz and great feeling the next day which is not that common.
My other regulars are Maple Leaf Indica, Grandaddy Purple from Ken, SAD from Sweet Seeds.
Bubba 76-ETS, Northern Lights-Nirvana, Yumboldt-Sagarmatha, Peyote Purple-Cannabiogen, all very good too.
