White jar plant: Not super fleshy textured, kinda boney. Touching it feels like touching a shoe insole that's worn out, so it's quite thin and not very plump at all.

Little sharp white spines all along the edge. Dark green with white and light green speckled spots. I noticed there's no hole to drain the water so I assume it's a hyper thirsty little plant and I want to take good care of it while I can.

Pink jar plant: A lot more plump and fleshy, touching it feels like touching a gel pad or something. Its spines arent as sharp as the one in the white jar.

I assume they're related/the same or at least very similar plants.

And their pots they came in have no holes, so I assume they're a high water intake plant if no hole drilled in the pot bottom means there's no need to drain?

How much sunlight is too sunlight? My room gets great natural light but will it need more, like directly on the windowsill? It's like 81 degrees lately and super hot and I just wanns make sure these lil babies live.

And how much water is too much, do you think? Theyre roughly like, 2/3rds the size of my hand.
