Anne what did your low tunnel cost to construct and where did you buy the materials?
Haha Clark, it is one of those ad hoc developments. There is a low soggy area down by the creek which I thought, to make a productive use of, I would have to build a raised bed, which I filled with top soil someone graciously dropped off for free in my yard. My son found a carport frame on Craigs list which we modified and put on top. I strung galvanized plummers strapping tape between the bars for added poly support and covered it with felt to also protect the poly. Here is the inside in late fall
.
I take the poly off in the summer and replace it with aluminet. The poly and the aluminet are held by ‘wigglewire’, making it very easy to switch out. The hoops are for extra row cover if the temps get below, say 25 degrees. This is needed only for the celery and lettuces. The idea is to capture ground heat which, in my area, usually says above 40 degrees.
Whoops, forgot to mention that I designed in a way to vent this which you see on the right side - just more strapping bent to hold the poly which is wrapped on PVC. Not shown are 2 vents in the apex of either side, and, partially shown is the solar powered fan which is thermistatically controlled.

That is interesting material.From what I read,it lets water and air through and also keeps in some heat. Brady

So I’m wondering how it holds up to wind, or, how the attachments will be made so they don’t tear the fabric during wind gusts. Is it recommended for exterior ‘greenhouse’ fabric? It looks like the row cover that I use and if so, it’s kinda frail.
