I have been wanting to try Northern Lights since it first was a Cannabis Cup Winner 2 decades ago. Today at a local dispensary I found Gorilla Glue #4 and Runts, and bought 1 each. Frigging $25 each! + tax and fees! Out the door was $68! Grrr! This is why I grow. Never forget the shakedowns at the clubs.
What a pleasant surprise this plant has been. My tent gets down to 18C at night and I get lots of pretty colours. Maybe that temp is hard for you to reach way down under. Also depends on the genetics of the individual plant. Some of my Pink Lemonade turned purple...some didnt. Enjoying your channel ..cheers!
