Sounds great to me! Depending on how they arrive, you might be able to see what kind of soil they're in. If they have more inorganic matter than what you've made, add some more perlite. If it's more organic, then add some more cactus mix
I bet they'll be totally OK! In the meantime, you can gather more inorganic materials (tiny rocks, gravel, sand, pumice, akadama, or whatever else is easier for you to find) for their soil!
I have no clue. Interesting hypothesis, though :lau
I'd expect the smell to be there at all times, and if anything, less during the hot hours. Pollinators aren't as active during that time, so producing a smell to attract them when they're not out and about wouldn't be matter
For cacti, mammillaria are a good genus to look into, and as for non-cacti succulents, haworthia and some echeveria are excellent
*gasp* how dare you! Lithops are simply the best!
They grow in Namibian deserts, if I'm not mistaken, so those have high heat in the
day and cold temperatures at night. They're not very picky about temperature. It's sunlight they enjoy. The more, the better
That explains the name! Not if it'll need repotting next spring, it might. Also not sure if it's a deep rooter or a shallow rooter, judging by its looks, probably the latter. That might mean that it doesn't utilise the bottom levels of soil as much
