Really? Really....?
Then I think you may need to take a gardeners class or something. I have a really large garden: Raised Beds-6 2'x12'; 5 4'x12'; 2 4'x8' and 2 2'x8'...AND a tilled area that is 30'x35'....
And even with all of that, I do not spend "hours of work each day" even during peak harvest time. I currently have over 100 broccoli plants growing, dozens of garlic plants; spinach and lettuce/greens/kale...carrots and leeks...and I MAY spend 2-3 hours a WEEK. I also have 432 seedlings started.
In the summer I will have over 50 tomato plants and a whole plot of purple hull peas...not to mention all the other stuff...
And even THEN I won't spend (averaged) over an hour per day...and we are still eating the peas, tomatoes and carrots I canned LAST year...and the pickles.
I think you may need to recalculate or get a little more efficient.
Wow! I’m very impressed with your garden description.
