In
my opinion the biggest benefit you can gain from growing
your own food is the ultra freshness, which removes all the middle
men involved in conventional food production.
I think it may be one of the
most efficient ways to reconnect more with the rhythm of nature.
For me the change was gradual
and I didn't notice the full impact of the reward until about the 2
year point of my WaldenEffect journey.
