(Edited to add: I forgot the part where the cloth costs money. I hope to amortize the cost across five years, but I can't reliably predict, because I am merrily voiding the warranty. I'll address the cost in a later post about cost of inputs versus value of produce. After I find out whether the terrifying July water bill can be blamed on the farm or the effort to revive an accidentally neglected lawn.)
