We're not concerned about yield on this project (Luce is scoutin' for suitable containers as I type!lol).
We have plenty of space for 'earth bound tommies', but what it does do, is create a more private space on our balcony/veranda ( whatever it's fucking called).
We don't do flowers and shit - it's about function - so 8 or 9 plants would do the job nicely...
