Hi, I have a big question can the gymnocalycium grow without the green part?

Ive done a fair amount of research to get the answer on my own and for some reason grow lights seem so complicated and information is overwhelming.

I would like to put strip lights under my kitchen cabinets. It’s an area without the sink and stove. It’s 18 inch from counter to underside of cabinets. I’ve read that 6500k color temperature with 2000 lumens? I’m just looking for confirmation and recommendations that have worked for others.

I want to use 2-4 mm grit for my small succulents, including Lithops, as I feel 3-6 mm is a little big for them. But I’m concerned that the smaller size might retain more water, and I live in Taiwan, which is a humid country.

Or maybe I’m overthinking it, and there’s not much difference between 2-4 mm and 3-6 mm?

Note: I'm using a 100% inorganic gritty mix.

Should she cut the top? Get it a new pot? Also it's constantly blooming i feel like that's probably terrible for it, even though the flowers are really pretty? It's about 6 years old. As a side note the plant in the background is a monster and it consumes every pot we have.

In my country, they call it angel’s tear, but that keeps sending me to the wrong succulent.

So i think i have bit more than i can chew when i buy a succulent pot for my mother and now this is happening. I water them once a week but i am thinking about scale it back to once per 3 week since the sunlight time has reduced. And sadly, living in an apartment where the sun is blocked by another house mean i cannot move this succulent anywhere.

What is causing this?

Got this guys from an ikea event at my school. Does it look possible to save or should I just put all that effort into a new one?

Is this a sedum blue tears minor?

I have these 3 succulents that need to be repotted and I’m wondering if I could make a garden. I have no clue what kind of succulents they are. They are about a year old

Purchased as is two days ago. Not sure if it's etiolated or just older. It's in a bright sunny spot with mixed indirect to direct light. The other one didn't "survive" repotting, just kept toppling over and lost a lot of leaves in the process so I popped it, repotted, and trying to propagate the leaves.

But yeah now I have concerns about whether I should do the same to the other one? It's unclear to me whether it's etiolated or just old. I am unsure whether it's a topsy turvy or like a cubic frost. The leaves are mostly very dark green edging to purplish.
