Healthy soil and sustainable growing

[Debbie Mcdonald <belynor@sbcglobal.net>]

I've always directly sowed my seeds and have not alot of experience with 
vegetable gardening. In starting our own seeds, must we use potting soil and 
if the world gets uglier;), then what would we do, sterilize the dirt 
somehow?? Nature does not do these things:). Do all of you have rooms with 
lights and heat pads and all that. I'm going to make next week time to start 
looking for abandoned greenhouses too:) Well, I have to get a new used 
vehicle first, don't want to put new tires on this one.
