Cold Temps...

Basically I flipped my timer to 12/12 on the 11th of December, and we've had Arctic like conditions here recently which directly reflect on the temps in my tent. At night it was getting down to 0 degrees celcius...anyways basically they havnt even really started showing their pistils, and after nearly 3 weeks at 12/12 Im almost ready to give up on them. I vegged them for 5 weeks too, so its not like I was trying to flip immature plants.

Basically what I was wondering was would it be a good idea to just change over to doing some autos instead? At least until the temps pick up here again, I could give them 20/4 schedule which would keep them warm from the lights and they'd only have a night time 1/3 of which "normal" plants need so the temps wouldnt drop even vaguely as low. Opinions?

Why not just buy them an electric heater? Freezing is def to cold and i do not believe it will flower until you get those temps up. Why let this plant go when you have put this much work into it?

Was thinking about getting a heater, just I dont think theres any room for it in my tent, the plants are crammed in pretty tight as it is!

Hang it then, heat may rise, but only the hottest air will go to the top, it will heat the whole tent.

So will I keep the fan system running with the heater inside the tent after lights out?

Fans inside the tent i would say yes, exhaust and intake i would shut off during the dark hours. May take a little experimenting, but should work well for you.

Buy a heat mat and place it under your plants. Atleast if you can keep the roots warm enough they will survive till temps raise up a bit
