The Door and Sign Hello Pack is the simplest pack in Growtopia, which contains 1 Door and a Sign for 15 Gems. This can be a suitable pack for newbies.Store Info:Own your very own Door and Sign! This pack comes with one of each. Leave cryptic messages and create a door that can open to, well, anywhere.
Even though it may seem very cheap, it is not worth it (unless you can't grind many Rock Seeds) because it can take insanely long for starters to grind even five gems; 1/3rd of the requirement.
If you want to splice them, all you need is 2 Cave Background Seeds, 1 Dirt Seed and 1 Rock Seed, which is very easy to mine. With these seeds, you may even get more than 1 door and sign!
