Just putting some band straps in the cart and took a closer look at their trusses.
Instead of flattening the ends of the pipe and drilling a hole through it, they make special end caps with a tab for bolting.
They're just about as cheap as the straps they bolt to but it would take 6 per truss, plus I need 4 straps per truss. I already have straps for my arches which are bigger dia than anything they sell. So 6 end caps and 4 straps per truss ends up at $210 plus shipping. I don't know if it's any stronger than flattening the ends and drilling a hole in them but it sure would look more professional.(way cooler looking - very important)
Mo money, mo money, mo money
I had a dreadful thought yesterday. Rest of the year, all spare money. What if after a year's work and $5k, I decide I hate every aspect of growing in a tunnel? Guess I could pour some concrete and screw corrugated roofing over it and call it a shop.
Gonna have to take a month of tunnel spending and spend it on me and my son so I don't get burnt out on no money, no money, no money.
Once it's done and I'm fairly proficient at growing, I do hope to find some restaurant to sell to and get come money back.
According to Farmer Jesse of No Till Growers(Kentucky), timing is everything for winter growing. You get stuff in and it grows full size just as it gets so cold that it stops growing. They continue to stay alive and your only job is winter harvesting.
