I have been growing outdoors for 35+ years and even in temps up to 48 degrees Celsius the plants do not suffer, as long as they are properly watered.
Where I am we get 2-6 days in a row with temps of 40+, multiple times each summer, and the plants survive without even one burnt leaf if kept hydrated, even if this means watering twice a day, so 32 degrees C is not going to bother them.
And yes, my plants are outside from day one until harvest and growing in soil.
I will however, put up a shade cloth cover if temps are going to be above 37 degrees at any time during the first 3 weeks of growth.
Cannabis is "designed" to grow outdoors and is a remarkably resilient plant and not some sort of delicate "princess perfect" exotic plant that some people make her out to be. Grow with confidence, 32 degrees is nothing to worry about.
Hope this helps, Organoman.
