well you had better have more down pat than me, I have only been doing this for 5 yrs. I just do allot of reading about growing and the different ways to grow food. I am still experimenting with all of it. From composting to what will and won't grow even odd stuff like rice. oh and I live in the PNW between mt ranges and well above sea level but close to salt water, got some freaky micro climates going on all the time.
