I always heard that pearls/jade and n’joy were slower growing varieties of the original marble queen. I found that mine started to really take off after I pruned it back and stuck a couple of fertilizer sticks in the pot. I’ve also got a marble and I gotta say, it’s been keeping up with it growth-wise lately haha

Looking at the pot, that’s legitimately the first idea I had if OP wants to go the malicious compliance route. I’d be tempted to build a table around the plant pot. Something like this (but for outdoors):

I struggled with this one even before I dropped it, so I feel your pain. Through some trial and error, I found that this guy likes lots of light and little water.

Light-wise, he’s in a east facing window that gets a ton of morning/early afternoon sun. Used to be in a spot that got direct sun but I had to move things around recently and it’s less direct now (so hopefully I haven’t jinxed it lol)

For watering, I know a lot of people say to do the “taco test” (i.e. fold the leaves gently and if they fold like a taco, then it’s time to water) but I found that was waiting too long between waterings. I just go on the weight of the pot now. I still wait until the soil is dry all the way through but not long enough that the leaves “taco”. I also feel like a shallow pot is super important. The grey cache pot is tall to allow hanging but the pot inside is only 2 inches deep (it’s a custom job, I cut a nursery pot in half). I’ve also found that it responds best to bottom watering because the water just kind of runs through if I go from the top.

Specifically for the echeveria - they need a lot of light or they get etiolated. I had to give up on trying to grow them because of that (unless you like tall gangly plants lol).
