Okay first off Lowryder is not a stable strain, because ruderalis isn't a stable strain and they haven't backcrossed enough to make it stable. Ruderalis is ditch weed with a very high CBN to THC ratio.

Second, you must have not been growing your kush strains right because I've had almost a pound off one Hindu Kush plant.

Third, White Russian doesn't have the highest THC percent.

Fourth, Yes Rockbud is a very good strain, not sure if its small yielding though.
