Heat is one thing sativa plants handle noticeably better than most indica dominant strains. A tent running at thirty degrees will stall a Kush but a Thai or Colombian line will barely notice, which makes sativa seeds a sensible pick for summer grows without air conditioning. Some of the temperature range data on https://hazesativaseeds.com surprised me, particularly how well a few African lines cope above thirty two degrees when humidity is kept low. Cold nights in late flower are the bigger risk for these genetics.
