Do anybody know if some strains are good for hot weather?
I think strains that are acclimatized to really hot weather do grow better, agreed. I live in a hot, dry climate and from personal experience I grew a number of kush cross african varieties and they grew like a bomb with little to no effort. Loads of articles out on the web for cannabis strains in hot climates.
Zamnesia posted a good article.
Anything Sativa from Southeast Asia, Africa should do well
