Jan,
Thanks for this. I just bought your last four SC10 cone-tainers from eBay. Had to drill down on some listings.
If you've got more and a willingness to significantly discount used containers, then drop me a note.
My son and I are building up a nitrogen fixing tree nursery before they timber and terrace the property.
Nitrogen fixing trees are also great for live pegs when addressing erosion problems. Can't grow enough of them.
Best,
Justin
