Lovely thread... glad to see foam is gettng out... The last three wnters I've made a cool room to overwinter my plants in... about 10' x 12 ' 8' tall... alll out of 2" foam... come spring I break t apart and make things from it.. lots of planters.. and other things... you'll see...
Here's a long planter.. wth a corner pond... all out of foam... it overwintered last year and was without a leak this spring
