Ways to get cotton
As of now, I'm stuck trying to make that Teddy Bear, which requires more cotton than even making a Tungsten set.
I got 2 seeds and waiting them to grow after watering each stage takes a lot of time, which makes a bad choice. What can I do to gather all the required cotton to make the teddy bear?
Currently cotton plants are the only viable way to obtain cotton. You also need cotton to craft the tier II armors, so you should get several of them.
When you plant your cotton plants (or any crop, for that matter) outside on a planet with frequent rain you don't need to water them yourself. So you can just go exploring while your farm keeps growing on its own.
