I'm playing Terraria 1.2.4.1 for PC and I've got to the point where I just have to scratch the itch of wanting a cool base, and I also want to set up some farms beneath the ground for things like Daybloom and Glowing Mushrooms.
When I've planted the farms, will they continue to grow while I'm playing in another world, or do I have to be putting time into the base-world for things in there to grow?
