I use a 90% shade net since the terrace gets unobstructed sunlight. No climatic controls, but it has misting system which is operated in the summer to keep the relative humidity high. For ventilation I have two industrial fans, that along with the misting system keeps the temperature a bit cooler but not significantly. I use normal Pune tap water, I had it tested once, it is really soft with very low total dissolved solids (TDS) 65 ppm and an ideal pH of 7.
