Thanks, Paul. I've had Mike's $50 and Up book since the early '70's. Read it then and it's been on the shelf ever since....or was until the grandkids moved in. I'll pick up his
greenhouse book. I've been going over your
wofati ideas and see some interesting things there. I suspect I have much the same mentality as you with regards to cheap and readily available materials. My problem here is logs are neither cheap nor available in quantity. Dirt and wood chips fit both criteria (both are free).
Composting the wood chips has the advantage of providing large quantities of fertilizer needed for an acre+ of garden. I've been composting chips on a smaller scale for several years.
