@Spliffi, Ihave a mate in ZA. He was growing fine. Native plants do well. And ZA is famous for many Sativa strains. Indica's do better in cooler climate. And common wisdom is that 0 C is the temperature when your have purple on purple strain. So, 13 C is just fine.
I am in Thailand. My coldese is 20 :D :D :D . Today, I am panting in 40 degree heat. Plant just stop growing in this heat. And I am waiting for my winter.
