Thanks for sharing the koelmaniorum. I have seen it mentioned in other hybrids but never seen one for sale anywhere in the UK or EU. That is a nice big plant. Must be fairly old? I too love the texture of the leaves. I was going to ask how you keep haworthia in a very hot climate but you answered that already to some degree. I assume the shade tolerance in nature comes from the fact they are either submerged completely (like the windowed types) or growing underneath other plants for protection. Do you see the respiration problem you get on aloes with the higher nighttime temps? I seemed to have stopped the leaf problem for now . Not really sure how. I have switched off one LED light on each shelf (to try to simulate winter) and increased air movement a bit

I still mostly suspect ventilation for your issue. I remember that the koelmanniorum was on the side of my house on a lower shelf unit stuck against a block wall with shade cloth on the other side so very little air movement, but very low light. It is still in mostly shade now, but on my front porch on a plant stand that allows for way more ventilation even though the porch is enclosed on three sides. It is pretty green right now - given that it has been warm but not hot here - we are still reaching 90F every day, not quite normal for November, but I think normal is probably out the window for the foreseeable future.

It is funny how you mention that tesselata is hard to find, here you can get them on the random plant shelves that grocery stores put out every so often. We have a couple growing inside with associated low light shapes.

Haworthias do show similar high night time low issues, but not as bad as Aloes do.
