    Paul, I loved watching how these protectors were built. Of course, I’ll never need one in my tiny 10′ x 7′ garden, but it was so informational. Thank you!

    I’m really excited about getting row covers! I have a question though, I visited the links you shared to get the row covers, but I’m having trouble finding the PVC pipes at Johnnys or seven springs. I noticed you used PVC pipes but on these websites I’m finding only wires. Could you give me a direct link or help me find them on these websites. Seven springs has something similar to what you used, but it appears it does not have a place to fit the re-bar in once ready to placed in the ground.

    I believe they suggest to just put the wiring in the ground but I anticipate that not being strong enough to fight against winds.

    Hope this all makes sense.

    Is it better to build tunnels or hoop houses oriented north-south or east-west? Or does it not make a difference?

    i tried an experiment back in 2010. i set up a hoop house using heavy mil clear plastic. i harvested some willow for the hoops. i didn’t use rebar to anchor the willow hoops and since it was not hollow like the conduit i did have a low spot along the edges. i did gain some space along the edges when i drove down stakes cut from tree branches. to fasten it i drove dowels into the hoop and the steak and then lashed them for added reinforcement. i compensated for that when i planted. I Laid down 2″ thick of fresh horse manure along the edges of the hoop house this would create heat as it decomposed as well as be good fertilizer. this manure had a lot of earth worms in it and the worms would be an added benefit for the next season, if they survived..the sun helped this decomposing and helped warm the air inside the house. i chose an inexpensive cool weather crop like spinach. my spinach lasted until December 6 when we had below zero temperatures and gale force winds. it happens in this area but not very often. in spite of the cold snap i still felt successful raising a crop when the winter temperatures are below zero. maybe i should have done differently but at that time i was less experienced than i am now.

    Hi Paul

    What is the thickness of the plastic used for the caterpillar tunnel and what material is used for the hoops, or what would you recommend?
