I'm not an outdoor grower. Heck, I'm barely an *indoor* grower!
But I looked in my reference books and came away with these tidbits:
from Jorge Cervantes "Indoor/Outdoor Grower's Bible"
"The best way to control temperature outdoors is to plant in the right place. Normally hot temperatures are common during midday in full sun. Cannabis virtually stops grwoing at 85F (29C). If you are planting in a hot climate, make sure plants receive filtered sunlight during the heat of the day. Also, plant them in natural breezeways so a breeze will cool them during the heat of the day." --also--
"Plants need a minimum of five to six hours of sunshine a day. Scout sites in the winter and try to visualize how the trees will cast shadows during the summer months. Remember that the sun takes a higher path in the spring and summer. Five hours of direct midday sun per day is essential for acceptable growth. More is better. Rocky terrain, hillside terraces, and grasslands all receive good amounts of sunlight."
I hope this helps!
