Thank you so much for your thoughts everyone! I really appreciate you sharing your experience with us.
The only other thing I can say about that tower I posted is that it rotates but then it needs a surface for that.
I’ve shied from getting really into composting because I’m just not sure how to have enough brown vs green for it to work as expected. I thought this option would make that less of an issue but that sounds like my own ignorance at work.
I’m really interested in growing my own produce here at home so it seems that I should look more into DIY towers. If I draft up a decent summary, I’ll create a thread for that.
