If you can find the right location outside, somewhere out of midday full sun but, in a good bright spot, then you can expect very fast growth!
From now until September is a good period to experiment, I have some containers with hair grass that stay outside all year but we don't normally go below freezing where I live.
If growing outside, when possible, you can expose your plants to rain but otherwise just keep the lid closed, stand back and watch them growwwww…..
