I have not grown twilight, but I have grown other purples from dutch pasion. It was reveiwed however in one of the three cannabible books as noteworthy for its flavor, but of only average potency. In my limited experience purples look fantastic but you can do better in regards to potency. The purples are favored in Amsterdam because they finish so early and they look so pretty. I'm done with the purples, if i want pretty I'll grow flowers. You can do better.
