Here chalk is not very expensive, I used about 16 units of 30 kg, for my whole greenhouse.It cost me about 45 bucks.
But the real hard thing was to apply the chalk to the up side of the greenhouse.
I have superb shodow and really nice temperatures inside the greenhouse, today outside was 28°C inside was about the same, thats great temperature.
In the near future we will get 35°C here.
