I've been playing Minecraft for a while - at first, you could only place it on sand adjacent to water, but then there was the option to grow it on dirt. I had read and always believed that sugarcane could grow on both, but would grow faster on sand. I have experienced this twice in Minecraft, once in the PC version and one in Pocket Edition. Recently, though, I read that they grow the same speed, and that several people have proven it to be that way.
I'm really confused now - could someone clear it up for me? Thanks ;)
