Hi Vivian
Yes I remember you for sure.
We spend too much time to be economic! Say 90 hours/week, but this garden is for demo and trials as well as producing. And ornamentals, fruit trees.
Composting and lawn mowing are not efficient in the sense of market gardening!
Harvesting leaf by leaf is quick as we sell larger leaves, 5kg per hour is quite possible.
Felix is at felix.laudenbach@yahoo.de and I am sure you will have a good communication. His no dig garden is very productive.
