what temp will cause harm

How cold and/or hot does it need to get inorder to kill a marijuana plant

Under 55 and over 90. And even then its going to take a bit of time to kill the plant. Over 110 and under 35 will prolly kill it fast.

thoough some sativas like triple digit heat. i would think anything over 103 w/o proper watering=trouble. has far has cold goes plants drastickly slow growth under 55 degrese, but it will have to be below freezing for a more then a night to kill them

so if Average TemperatureMonthly average temperatures range from a high of 92.5 degrees to a low of 34.9 degrees.

i could grow all year long right? with maybe on cold nights cover with a green house?

if you have it good and watered a few days before it will last through 110 but if you don't 90 can kill it and anything under 35 you need to build a tent and use a space heater to shoot the heat through

55-95 with lots of humity and no aircirculation will cause heat stress n will be dead in like a couple days

I've got no "Cold Weather" experience - just whatever is common knowledge.

But hot weather, that's a different story! I've grown outdoors in Southern California's "Inland Empire" (not too far from Palm Springs, OK?). The early Spring was OK, but from late Spring right through the end of Sept.; the high temperatures ran from the very high 90's to the 110's - every fuckin' day! Normal Summertime highs run around 103-105 degrees f., with single digit humidity!

Hot weather like this does not kill cannabis (if you watch over it like a baby). But it really slows down the growth! I grew from Spring almost all the way till Halloween and my plants were only about 36" tall at harvest (more or less). The only reason I did this was because (at that time) I didn't know you "couldn't do it"! I never tried that again - but don't tell me it can't be done!
