Master Kush is a cross between a pure indica strain Hindu Kush and Skunk #1.
 
This strain provides a brain-focused high and takes the weight off your shoulders, which is awesome for after work.
 
This bud is unmatched in its pain-relieving and sedating qualities.But no matter how nice and relaxing it is at low doses, excessive use entails a heavy couch-lock, so be weary of the Master.
