Royal Kush automatic grows into a compact auto-flowering cannabis plant but grows more in height than other auto flowering sorts do and so reaches a height of 60 to 90 cm. After about 8 to 9 weeks it is “ready for take off”. Its flowers smell like fruits and it will give you good returns. However, its buds are not as dense as in some other autoflowering varieties. It provides you a clear, happy high.
