Are there any strains that u guys can think of that love the COLD.

I'm talkin daytime temps no more than low 70's F
and night temps @ maybe 50 -55 F

another variable being something that likes high altitudes (over 10'000 ft) in Colorado and very low humidity.

This would be an indoor grow. w/ 600 watts hps

I'm helping my sister set up, and she just moved to a ski town in a "rustic cabin".

her grow area has been running w/ no plants yet, and these are the temps shes giving me, and she doesnt like to heat the house much....likes it cold, and the grow is adjacent to her room.

any ideas?

im not sure what the above me meant when he said 'looks all good to me' (unless im too high to get the point), but the strain my friend reccomended me to grow, ak-48, he says he grew without temperatures above 74 degrees. So i'm sure it must be a well adapted cold strain, id go with that.

Cold just seeme to slow stuff down...But being In AK the temps flctuate wayy too much not to have a heater of some type and I'll bet Colarado is the same.Ruddy indica didint mind the cold but its a waste of time indoors. I'm guessing some of the canadian strains from further north or any of Owl productions seeds(if you can find em).
Get an infared ceramic heat lamp on a thermostat to keep temps in check.
Owl productions seeds were bred by felix in high altitude feilds in switzerland made to resist cold and mold.
Most plants will thake the cold as long as the root ball dosent freeze.
Good luck

There are a few strains that are well adapted to high altittude and cold temps. Granflora, Heaven, Purpurea Ticinensis, Walliser Queen, Red Valais, Alp King and Ethiopian Highland. There may be others.

Below is a list of cold resistant strains but how they do in high altitudes is not made clear. Not all will be good indoors either, so read carefully.

I am currently growing Mango from KC Brains. My day temps are around 75* F, and the night temps go as low as 49*.

They are not affected whatsoever, mostly because they are 100% Indica, and they are a very hardy strain.. That being said, growing a 100% Indica would seem to be the best choice.

Felix is not available yet, he is still locked up. So Owl's Productions is not up for selling seeds right now.

Felix is out unless he went back to jail...........The problems with pure indicas is the mold issue and this is compounded by the cold making condensation on the plants

i dont believe the altitude will affect anything if ur not groing outdoor. the main high altitude difference for the plants is the light intensity. at higher altitudes the sun is much more stronger.

the cold temps - she could easilly instal a small wattage heating mat for gardening or similar. they are low cost - and they create only a little bit of heat if u get the right one - and they wont heat up the whole room - just the roots of plants, that is - if u put it under them

the low humidity will definetly work on her side there. just make sure she has good extraction - since the plants will create a lot of humidity - and that also brings down the air temps.

in winter conditions i think it might be a good idea to let the entrance of air be passive - that meaning - let it pass thru all of the house(cabin - to get warmed up. too cold air directly blowing on the babies aint too good.

in that way i think she can grow almost any normal indoor kind.

hope this helps her.

peace

Eth highland is a pure sativa and I would not grow that in colorade lol...
I would go with KC brains Afghani Select

Indicas won't cut it in most winter conditions due to their lack of mould tolerenace. The only thing that will are pure sativas that are indigenous to dessert areas where the overnight summer temps drop 10-20degreesC BELOW zero every night...that's 14degF to -4degF every night of every day they are alive in the summer.

RooiBart
EthHighlander

and other pure African sativas that came from dessert-like areas in Africa can cut it. As should be able some pure Mexican sativas that are also near-dessert dwellers...but that I'm guessing at. The rooiBart I know for a fact will survive in most winters that have regular sunlight during the day, even if the overnight low drops well BELOW freezing...and they are NOT prone to mould due to their airy lambsbread buds. Trick is to get them up and established with a good stem BEFORE the frosts set in.

Sow them in the ground early August in the NthHemisphere for a harvest in early to mid Febuary BEFORE the increasing photoperiod triggers them BACK into veg. They do well in soil that would support a good 'bulb' grow/population. So mix in some 'bulb' potting mix into the ground if you tend to attempt it and adjust pH prior to sowing with an appropriate sprinkling of gardener's Limestone (fine lime).
