We started the day really excited about putting our first Poly Tunnel or Hoop House together. Everything was going smashingly, until we tried to bend the PVC into arches. It was REALLY difficult. We were using PVC plumbing connectors.We are using 3/4" PVC which is about an inch across in total. We were bending two 8 foot long pieces to meet in the middle to the connector. It would be a tall hoop, but kinda cool I thought. When we got it just about there the connector snapped. It is about 9 degrees celcius today, could that be it?
