Will they live?? Please help!!

My girls were exposed to really cold temperatures in my garage for about 20 minutes last night after using spider mite knockout..they look dead but I'm hoping they are just in shock.
Any help or things i can do? Should I put a space heater in there?!

Heres a before and after pic. It's crazy how quick they changed

Looks like 3 survived. When you expose plants to freezing temperatures the cells rapidly expand and then rupture as the water in them freezes. My condolences.

Which three?!
is there anything I can do to help the poor girls?!
thanks for the reply
they can freeze and rupture in 20 minutes?!

uh oh. shoulda put in a small heater.

Shoulda or should now man?!

They will live! You HAVE to remember, cannabis is a weed! They thrive and want to live, just baby them from now on and be cautious of your temps!!!!!!

Are you sure Doug?!
should I put a space heater in temporarily?!
im always cautious of temps in my room but stupidly left them in -20 c to mite bomb them (about 20mins). Was trying to protect my animals should have thought more about the girls

you'll know soon enough, like in a day or so. sometimes if the damage isn't too bad you can prune off any dead and just resume your grow. put the heater in now. get a min/max temp gauge and see what they look like tomorrow. try to keep your min temp above 50F

My box is at 65 and always stays between low 60's to 72.
is there still good to be done by the heater or would it just cook them?
sorry for all the q's guys this is my first attempt

P.s thanks for the Replys fellas!

hmmm. i'm surprised that low 60's did that kind of damage but yes put the heater in and don't let the hot air hit the plants or you'll be dealing with a different set of problems.

They were in my garage at -20 c for about 20 minutes while getting bug bombed lol that's what did it to them .
In a 3x3 box I'm not sure how I would put the heater in while not letting them get hit by the hot air

dou have any germinating heat mats? they only go to 70F and would be perfect.

I had spider mites once, after treatment, they looked like that (similiar situation)

I tried to save them for a week and gave up, so threw them out in the back yard (4 weeks ago)

I went out yesterday to my mulch pile, and they are all geen.... so I think they probably would have survived!!

Don't try to super-heat them now. You will do more damage. Just put them back in their normal grow space.

I don't Danny! Thanks for the tip tho.
damn so you think it was just the spider mite knockout oregong?
Thanks WDIK I raised the light a bit and will leave them in the normal grow space.

Define really cold temperatures.

-15 /-20 c for about 20 minutes

Rip my brutha! Just kidding.. i think they be fine keep in mind that it probably the bug killer that did it not the cold temps it would take more than 20 min to destroy them. Theyl b ok!
