I have grown out the Northern Lights origanal special (KCB), Purple #1 and Twilight from the Dutch Passion guys for almost a decade, and i can say from my experiences with these varieties that not only are they some of my favorites, but they are some of the most consistent genes i have encountered. They do exactly what it says in the discriptors - mold resistant, thrives in the Northern Hemisphere, vigorous, productive and beautiful product. I rely on these babies to pull the majority of my October crop in and sometimes i can leave them to go further - due to their intense purple appeal, some times the products comes out jet black smelling of winter berries! My friends call it space skunk lol.. This is perhaps due to the fact that the massive colas toward the end of september, resemble the shape of satalites.. I owe a lot to the DP crew for being truthful to their customers. They are reliable, yet reasonable people with a real sense of love for what they do..
