I'm planning 30 cm apart in rows (~12 inches) and 0.5m rows distance (~19.5 inches). But, isn't it too densely? I'm even considering 30/30 cm (30 cm rows distance as well).
Does planting density actually affect to crop amount/tubers size? Vines are usually very long, but they will be always much longer than distance between plants, so 30 cm or even 50 cm should not make any difference. From other side, distance like 30 cm should be enough to give a room for tubers in ground, what do you think?
When searching for info, I got various recommendations, so I don't really know what to do.
