Cool thanks for the info.

"That sucks mate, I feel for you. Just a thought could you trickle water over a shade mesh screen at night to increase the cooling of the water? Could set a timer for the coolest time before sunrise."

Brian, I bought a sprayer/mister set-up from big B and put it in my greenhouse. Ambient temp this week was up to 44C, while the mister system (with vents open) kept the temperature inside the greenhouse at a balmy 36. The sprayer/misters each use 4L per hour, so only 24L used per hour and I'm very happy with the results. Way cooler than outside. Water temp max at 26C.
The plants in the GB's also thrived.

Brian was looking at your thread. I see this is quite old. I too am in SA and thinking of having a go. You still running your system ? Any tips for starting out ?
