There might be more articles, or even places to buy the strain, but I honestly didn't look very hard. I only tried a couple variations and only loooked at a couple pages of each. I found thses to on my second Google, which was buy+Chernobyl+cannabis+seeds. If you don't see what you're looking for with those two links maybe you'll find something with variations on the search I did. Good luck.
