I hope you manage one day to make that. I haven't tried the coffee from the roots yet. Let’s see if I have enough. You know what you could do. Gather the seeds like you do and put them in pots. Compact the soil a bit. Make sure the nitrogen is low and they should be growing. Worth trying.
Treat it like a veggie plant and grow in pots or raised beds. Hahaha !LOL
