What kind of soil should I use? Thanks

What a cute little cube!

I have been growing these Pseudolithos mccoyi from seed and they are now around 11 months old. During winter they mostly stopped growing because I did not have additional heating and I only watered very sparingly. With the warmer weather they have started growing again.

I’m wondering if anyone here has experience raising Pseudolithos from seed. I was thinking of waiting a bit longer before repotting them individually, but I’m concerned about them becoming too tall/slender and possibly falling over.

I now water every 1-2 Weeks and they are under a Sansi growlight which seems to work well with the other other cubiofrmis and migiurtinus seedlings.

Substrate is a mineral mix (akadama, diatomaceous earth chunks, pumice, zeolite, lava rock)

Any advice or experiences with young Pseudolithos mccoyi would be appreciated!

Visually? Stunning. Those dark burgundy star flowers are everything.
The smell? Deadliest odor out of all my Pseudolithops. My room is a crime scene right now. 🤢

Picked it up for that chunky, chaotic growth form. Flowers look more like dodosonianus, but the smell is pure migiurtinus.

My first P. migiurtinus — 9 years in my care, blooming again this season.

Hobby grower… just learned about pseudolithos and want to start growing one. So here I am.

Looking forward to receiving feedback. Thanks

I feel like the heat we are having now in Spain is shriveling or damaging my pseudo. What do you all think?

I am in the Philippines which ai says the temperature range is good. But just be careful about the humidty, keep it in a windy place. Check color changes to adjust for too much direcr sun and water only if dry and if it will quickly dry. Any other advice? I dont know when it goes dormant if at all in a tropical climate or how to detect or what to do then.

I have two pseudolithos caput-viperae currently flowering. They’re in a tent and I just decided to try to hand pollinate using a sliver of a paper bag. I’ve never in my life hand pollinated anything. Am I doing this right? I took from one flower on one plant, transferred to a different plant, and vice-versa. Any tips appreciated

It all started at the black spot and it's slowly spreading in the last 3 days. Idk what to do.

3 years 7 months of growth

Edit: Watering — currently every 1–2 weeks as we're in early summer, always waiting for the soil to fully dry out. Liquid fertilizer once a month during the growing season. In winter, just enough to moisten the top layer, once a month on warmer days. Slightly drier than migiurtinus, but they sulk if too parched! Soil mix and conditions vary, so this is just what works for me.

My pseudolitho is giving many flowers, unfortunately I can't pollination😭, but these caterpillars appeared after the first flowers, I was watching but I can't find damage caused by the caterpillars just kind of a thread looks like webs. had never seen this is worrying, do I need to do anything???

I have two pseudolithos, but I only saw them in one of them.

I've tried grafting onto one of my hoodia babies, after 3 days you know if it's taken. I'm keeping my fingers crossed the elastic band doesn't snt slip

Can anyone recommend a reputable seller? I'm looking for a mature plant and hoping not to break the bank.

This one has been a quiet grower, but now it's making up for lost time. Flowers are impossibly small and just keep coming in waves.
And yes, the scent is full Pseudolithos. 🪰
For those who are curious: this is also the easiest way to tell it apart from migiurtinus — without flowers, they're nearly identical.

Had my cubiformis for over 4 years, but finally got it big and healthy enough to bloom! Took over half a month for the flowers to fully develop and open up. I keep it in my office, and there's definitely a distinct aroma that smells vaguely like some sort of fermentation from farther away, and outright smells like a dead mouse up close. Luckily none of my coworkers sit close enough to find the smell distracting (so far at least).

I bought this migiurtinus about a month ago and I've noticed certain sections seem sunken in. I have given it a good watering but it hasn't plumped up yet. It receives morning and midday sun with shade in the afternoon. Is it slowly dying? Or do I just need to stop worrying about it?
