    Next year I'd like to try a real small outdoor grow but I live where it gets up into the 115 degree range in the summer. Does anyone have any recomendations for heat tolerant strains? I was thinking maybe some of the african landrace breeds or south african varieties like durban p etc.

    That's what I thought at first, too. But afghan and similar pure indica (afghanica) strains are from the middle east..where it obviously gets very hot.

    moroccan, as well as other african breeds...s.e. asian sativas, brazillian/colombian.

    if you harden up the plant . . . theoretically couldn't any strain be tolerant of high heats?

    Go with a sativa dominant strain.

    Mandala claims that most or all of their strains are bred to be heat tolerant...you might want to check them out.

    I've read good things about them.

    I believe this to be the case.

    I have a friend that grows outdoors where I live, and the last week has been 5+ days of 100+ weather. One day was 112.

    He grows multiple strains. The only plant that had a problem was a sativa, but it was YOUNG, maybe 4-5" with 3 nodes. The other plants with healthy root systems were fine. Their leaves curled up and pointed up slightly, but I am told this is normal in extreme heat.

    As long as the plants are established, healthy and have water, they should be fine. Heck if anything they seem to grow like crazy in the heat.

    Start early before its really hot, and veg under CFL's until the plants are well rooted.
