veggie protection in our hot Aussie summers

About 5 years ago we had this great idea of making a hoop shade house to protect our plants in the  extremely hot summers we have here in Australia.
We built the shelter with just three hoops. 2 inch poly agricultural pipe over metal star pickets forming the skeleton. We then covered it with nylon bird mesh to keep out birds and other  nuisance animals and then covered it with high density  shade cloth.
We found that this was totally impractical as it was too shaded and the plants went spindy  and leggy and  didn't thrive.
We removed the shade cloth and just left it for several years with just the mesh.

Recently I had a whole pile of potatoes sprout  and I suggested to Brian that we plant them up at the farm in those garden beds, As they would have no protection we mulched them heavily with sugar cane mulch .It has been extremely dry up here  and the mulch has helped greatly.
So yesterday I suggested to Brian that we really needed to put some cover over the potatoes or they just would not survive the next  couple of months and we would loose them.
So we decided to revamp the  hoop  structure a little.

Where we originally had three poly hoops we now have five.
We then screwed in  three horizontal rows of metal as   strenthening supports to the structure.

For this we used some old metal tent poles that we had been hoarding for years for no particular reason but knew they would come in handy one day.
We then made a very lucky phone call to enquire  about the price of shade cloth . We first rang our next major town  which is 32 miles away (thinking that our little local place wouldn't stock it. The price in the bigger town was $13.90 per metre for 3.6 metre wide cloth.
We decided  just to check  our local fellow (6 miles away) to be really surprised that he quoted us $5.60 per metre for the same width. We went in immediately and purchased  the required amount , double checked the price, paid and made a  very quick exit as that was super,super cheap.

We attached the shade cloth  ,making it higher up on the back side of the cover as the sun is more prominent on the  front side most of the day.
On the side where it is hanging down we attached a 7.5 metre long 1 inch diametre plastic pipe so that we could use the overhang as a roll up blind, that we have up for most of the year and just roll down when the heat is extreme.

We think that this amount of shade will be the right amount and that hopefully we will grow  lot's of healthy vegetables under here. Our blue Cattle dog Tilly certainly seemed to be enjoying the shade as she barely moved from laying in one of the gardens for the whole day while we were  working there, even today she has spent a few hours under there9 even though there is plenty of other shade for her.)
So here's hoping this works,I will update you all at a future date to check on the progress and see how it goes.
So a cheery farewell to all,
regards,
Jane.
