Are you doing two plants of the same strain or do you want two different plants? It might be the only auto, but that purple lemonade sounds interesting, to me. Blue Diesel looks nice (for my tastes), too. Have you ever grown White Rhino? That's one that a buddy said he's bringing me some seeds for.
Edit: I overlooked where you asked for two seeds. I want you to have good daytime smoke, lol. Went with Tangerine Dream and Blue Diesel.
