Strains for High (or low) temps?

OK. A lot of us indoor growers often have temperature control problems so I was wondering if anyone has any suggestions for strains for high (or indeed low) temperatures?
Let's stick to the point and not turn this into a thread about venting or air-con or anything.
Oh, and feel free to add any that are particularly sensitive to temp variations.
At Redeye's request (post 6 below) we will add humidity tolerant strains to the discussion.

I'll start off with Violator Kush. I did a 600w loft grow once with mental temperature deviations and they still came through with 16oz. Hermied a little (4 seeds in the lot) and extended the flowering time a couple of weeks though.

Good thread Idea, finally had a chance to catch up on most threads I've looked at in a while :) I managed to get me that LED as well they're too sick (link in my thread lol)!

Mostly Sativa's like higher temps, I've had an Amnesia Lemon pheno from Barney's Farm that thrived in 35-40* no problems at all, Indica's are good if you have an outdoor shed that your growing in as they can take quite a bit of cold, more specifically Dinafem's White Widow and G13's Sour Candy was fine at an absolute minimum of 10* for a good 4-5 weeks during my winter of shed growing.

Currently I have done 1 grow and just started a new grow with Bomb Seed's Berry Bomb strain and that was/is an extremely resilient hybrid especially with regards to PH and temperature, can deal with temps in excess of 45-55* on a bad day and it doesn't even point up or show signs of stress, it can also withstand cold nights of about 15-20*.

G13's Pineapple Express is a really resilient strain as well, can take both heat and cold very well.

Generally Hybrids are the best for 'bad?' environments lol :)

Stay Frosty!

Ok good info there matchbox. For those of us that get REALLY cold during winter months are there any indoor northern hemisphere strains that thrive in cold temps? I have grown only bagseed in the cooler temps for fear i'd screw em up with the temp dropping from now until early april.

Strains that the color scheme enhances in colder temperature ranges i.e. purple strains.

i understand you dont want to get into venting and a/c and only temp. i would think that humidity/temp. rated strains would help.

Mandala claims their seeds are heat resistant. Quoted from their website:

"Whereas a heat susceptible plant will show slow or stunted growth, yellowing of leaves, wilting, leaf drop, hermaphroditic flowers, etc. our strains tend to grow and flower even at temperatures up to 50°C/120°F if necessary. This does not mean that temperatures above 35°C/95°F or other stressful conditions are desirable and should be sustained for cannabis cultivation. But, they may be beyond the control of the grower at least for a certain period of time (summer months, etc.), during which the plants must rely on their resistance for healthy development."

That is interesting to know. I have very hot temps during summer in my area.
