For building tunnels with slitted plastic or Agribon. Most effective if spaced every 5' or less. “Hoops” are shipped as straight 74" flexible rods of 10-gauge wire. Stick one end in the ground and then stick the other end in at the desired tunnel width to form a hoop. (The shipping weight reflects the FedEx surcharge for these over-long bundles that look like we are shipping you a pool cue!)
