Vermiculture tower above series of wicking beds

Hey friends. I just posted this simple vermiculture idea and interested in your thoughts and feedback (posting there welcome too).

My criteria for this build was:
1. Gaining growing space (not losing) with the addition of a worm farm into my wicking beds (precious real estate!)
2. All the benefits of vermiculture automatically fertilising my wicking beds
3. Embody my ethos of using repurposed materials

Let me know what you think.

Cheers. Graaly.
