I tried using 1/2" diameter conduit poles and parachute chord. The poles are ten feet long. 3 feet in ground, 4 if you count the raised bed. It sagged. This year I replaced the 1/2 inch with 3/4 inch conduit, which cost 6 bucks a pole. Two grades of steel. The thicker poles are 30 dollars each, so i used the thinner steel poles. See how it works. It's only about 7 or 8 feet long. Here it is with the 1/2" poles.
