If you go to youtube, subscribe to Subcool's channel, subcool420. He does a show called the weed nerd, and talks a lot about his strains, and the certain phenotypes he finds, he likes, etc. He also posted a lot of vids a while back that were specifically for his strains, with him talking about it. That's where I would go. On the latest Weed Nerd, he showed his veg room where he had about 10 Vortex's popped, where he was looking for that "certain pheno".
