In cold temps- growths slows right down and once you bring it back up, it will speed up again. So yes, keep them warm and they will grow again just fine.
if you cant bring temp up- they will still produce a harvest but it may take many weeks longer, but as long as the plant is getting enough light it will grow just slowly in cooler temps.

I'm sorry I have little to no knowledge of Celsius, I'm so used to farenheight.
Chlorophyll starts to degrade below 67, growth will be negatively effected below 67 (should never happen unless you are trying to purple or your flowers are finished and your focus switches to ripening.
Once flowering period starts it is akin to starting a countdown. The plant starts new hormonal stages, with each stage building on the one before, pre-flower, stretch, budding , fattening, ripening etc. If development is slow it can only do what it can with what it made.
Growth will still occur.
Optimal photosynthesis occurs at a leaf temperature of 86, but keep in mind trichomes degrade above 87.
Terpenes and flavinoids can start to slowly degrade above 67.
Maganese has serious trouble uptaking through root system below 64
Which really messes with bud formation.
Try get top of canopy to 86 and hold it there, aim for ambient 82- raise light source to reach canopy 86 or there abouts, this will maximize photosynthesis from there on.
Just keep an eye for the usual suspects on heat stress. Good luck

They should just at a slower rate. Their metabolic rate has slowed with cooler temps.

Removing of Big Leafs in Flower Phase ????Does it make sense to remove large leaves in the flowering phase to give the plant the opportunity to send more energy into the flowers or should you leave the larger leaves on because the plant also photosynthesises through them.

Increase of Terpene production of my indoor plant (Indoor no cannabis smell, with growing buds)Folks, how can I increase terpene production and enhance the aroma of my indoor cannabis plant, which currently has larger flowers but lacks the noticeable smell observed of my outdoor plant? Or is it normal normal as the plants have different conditions and stress level?

Main versus secondary maturingThis secondary lower buds seem to be maturing faster than the main colas. The pistils are turning dark faster on the lower than the upper. Not by much, but it's noticeable. Maybe a week or so? BUT, should I take the secondary buds first and leave the main colas to mature more?

These have been grown in 91 degree heat for their entire time growing. I can't change that the heat killed off some trichomes. But what is your opinion on the doneness of the trichomes that are there? If the pics are not clear enough I can use my real camera versus my phone. THX

Colas to close to each other?I am a little bit worried about the colas growing quite close to each other, and quite dense (the side branches are basically all start to grow into the main bud of the cola). Should we do something to get a bit more space and ventilation inbetween? (more pics and video in diary)

Different Phenotypes?2 plants from the same seed type purchased together. They look really different. I thought the one with the swollen calyxes was hermed, but research said otherwise. But one has trichomes and decent smell while the other has faint smell and no trichomes to speak of. Thoughts?
