Awesome! yeah, there’s a variant where you can seal the jar, but for the most part exactly what you said is the norm. I’ve had mine for roughly 5 years now, but I added shrimp and trim it back about once a month or so . I don’t even feed the tank more than a few times a week.

You should look up “Walstad planted tank”. An all plants aquarium you don’t ever have to mess with (except to trim if you want to)
