Hard to say what it is, being so stretched out; normally the leaves should be closer together on their stems. I'd try to gradually give it more sun.

Yes, without more sun, it's probably on it's way out...that's pretty bad.

Do it very gradually as suggested above, it's VERY susceptible to sunburn in it's very weak state.

Point of fact, I'd slowly get it growing more strongly in more like half to full sun, then take a cutting that looks normal (which this doesn't..this is like a stringy rope), and root the cutting. This plant will be too weak to bear flowering stems, they're too skinny and weak.

And put the cutting in a MUCH smaller pot...that pot is WAY overkill and probably stays far too moist for that size plant.

Well, I would say yes, if you don't shake all the soil off the roots. You'll find that most of your soil is empty (remove it). Unless you're very careful with watering, that much soil is more than a waste and holds water that well succulents don't like.

Careful repotting when its a loose root mass, should not be a real disturbance. I would expect that plant to take up somewhere between and 4 and 6 inch pot. I don't think it'd suffer greatly being put in a 4 at this point. You may find you do have to get a little creative with stuffing it's roots into that size, but that's about where it should be, IMO.

What is the potting media? I'm not a big proponent of specialized soil mixes, but that looks incredibly peaty and water retentive for a succulent. Note, you can manage any media with careful watering, though most prefer to use something much more well drained like a cactus and succulent mix or the obiquitous gritty mix (you can google that or should find plenty of articles in soil or house plants forum talking about it).

I have used gritty on my aloes and citrus and it works surprisingly well, especially for winter inside when things are semi-dormant and can easily get too much water.

Actually sand is not generally good indoors. Yes, lots of people make that observation that many pre-packaged mixes all seem to be the same (no matter what the bag says).

May I suggest you post a photo of your plant and ask about growing conditions and soil suggestions on the Cacti and Succulents group. I grow everything (more or less), but someone more specialized could probably give better advise over there.

I'm in Arkansas, I assure you that you have nothing over me in heat and humidity. I remember returning from Banff in July one year, and walking off the plane and thinking 'I can't breathe with this soup'.

Difference between nighttime and daytime temps shouldn't be problem; even 20's is pretty warm (I am assuming that is C). My daytimes are in 30'ties C, and nights drop to 12*C sometimes - I wouldn't mind if that was every night! :) Cooler nights are actually pretty good for plants. I am north of Toronto, On, and weather is quite similar to yours in Montreal.

Pls. do not use sand for potted succulents regarding what you read on some 'blogs'. Yes, it could be used for some, but only if you really know your plants. It is best if you just don't use it. Grit is great addition or pumice; but if you don't have (or not easy available), use lots of coarse perlite. If you mix perlite 50/50 with the Cactus & Succulent soil, that will be quite an improvement.

If you can, keep plants outside. But make sure you acclimatize it very slowly, since it is very etiolated and most like very weak. You need to get it into better light and water properly - sparsely is not proper for succulents. If you pot it into well draining mix, you can water thoroughly when needed. Pot seems to be very large for your plant. I would repot it into smaller pot.

Etiolated plant will not 'revert' even if you give it much better conditions. If my plant, I would trim/prune it extensively. If you want some ideas, pls. ask.

BTW, here is Cacti and Succulents Forum if you are interested to read more about succulents...

This is absolutely 100% the variety of Kalanchoe referenced by the first reply. I actually propagate hundreds of these per summer. Your plant is fine but I think I may consider a smaller plastic pot inside your decorative one. I literally keep mine in 4 in pots until full grown or first signs of leaves yellowing at base of plant. Then I repot and begin to cut each branch back 2 internodes. If you repeat this regularly and give the plant lots of wind simulation you will end up with one like this in a few years.

Your plant is very good looking and you gave great tips regarding regular pruning.

I respectfully disagree with this part of your statement: ..."Your plant is fine"...Most are of opinion that is very etiolated, so while it looks otherwise ok (no blemishes-bugs-diseases), it is skiny, weak and probably of lighter color than it should be. So I wouldn't say it is 'fine'. Hope you don't mind me saying this, it may sound like nitpicking...and maybe my understanding of 'fine' is different. But OP should give it more light ASAP to grow more to what it should be, and prune to get plant growing to it's best potential. Then it will be fine specimen...

Don't do it all at the same time. First repot (smaller pot, well draining mix). Acclimatize to better light. That will help for plant to get established and stronger. After about 2 - 3 weeks, I would prune quite a bit - leaving just 2 sets of the leaves. Stretched stems will not 'shrink', but you want plant to get stronger. All pruned off pieces could be rooted for additional plants.
