Which seeds did you buy even though your grow room is full?

I feel like I'm addicted to buying, I'm scrolling through all the available delicious strains and I am close to buying even though there is no room. So which strain melted your heart so much that you just had to order them? I am really close to pull the trigger on Dark Ghosttrain from Rare Dankness, its Grape Ape X Ghost Train Haze #1. Which is yours?
