Look at the images here:
I may be wrong, but aren't Cobra pitchers always surrounded by other vegetation? All the pictures I've seen of them in the wild, they are growing with some kind of vegetation. Wouldn't this help aid them when it comes to keeping the soil temperature low?
For those who are growing the Cobra pitchers, how are you growing them in your pot? Is it just bare soil with your cobra pitchers poking out? Wouldn't this make them more exposed to higher soil temperature?
Also does anyone know what kind of vegetation that is growing with them? I don't think it's grass but who knows?
