Play Misty For Me

What is the general consensus to having this kind of setup inside an aquaponics greenhouse? Would it be difficult (and expensive) to set up and run?
Say, set on a timer to run for a few minutes every hour when needed during really hot spells.

I wouldnt be that keen on some of the DIY ones i've seen, where a fan is used to blow a mist of water, fed from a small tube taped over the front grilling of the fan. Water and electricity tend not to work too well together, lol!!!!
But, something like this would be safer, i would think. Obviously non commercial scaled systems wouldnt need to be THIS big, or fancy, but the general idea is the same, and the pic is just to show what i mean
would it make the atmosphere in there a bit too humid for plant growth, or what?
Opinions, anyone?

Misting is certainly a way of reducing temperature... and "misting" fans are available... which might be a better option...

But any greenhouse, especially in a hot environment should include croos ventilation controls.... wind up curtains/vents.... circulating fans... and extraction fans/vents....

First.... and then perhaps some minor usage of "misting"... if it's only being done for temperature control... rather than actual irrigation/fertigation....

My question is... why????..... why would, or do you think... a greenhouse is required in your climate????

The biggest problem you're likely to face with a greenhouse in such climates... is humidity and mildews... misting would problem only make things worse.... especially in terms of mildews... unless the other ventilation components were in place...

I'm not talking "greenhouse" as such. But something that will contain the system and protect it from the elements and go some way to keeping down the bug count.
Certainly, i plan to have some shading, air circulation/cooling and the ventilation you mention too
But it gets bloody hot in the season, so any extra cooling will be good, i would think
Plus i plan to try to grow stuff not native to the place where this is being set up (As difficult as that may be lol!!!)

Shade cloth is a must IMO.... and the misting may help...

Humidity and mildew will be the problem though... and cross ventilation and air movement (stirring fans) are also a must IMO...

It might be possible to get oscillating "misting" fans... and I think they'd be a better option than overhead sprinklers...

I've also heard of people basically trickling water directly over the shade cloth for cooling... similar in principle to what we here in Australia call a "coolgardie safe"...
