Can you post a picture of it? I'm wondering if this might be a humidity issue rather than a problem with light. I've grown several Kohleria and have always found them to be light-loving, but at times can get crispy leaves even in relatively humid conditions for me.

I'm not sure Kohlerias need/tolerate all that much light.

Mine do well 6 inches or so under shoplight-type fluorescent fixtures. I moved a plant of K. "Longwood" from a bright location (under an LED fixture) after noticing leaf curl/scorch, and it's doing better under the end of a standard pair of fluorescents.

I suspect that a small plant used to artificial light couldn't handle even a few hours of sun, but that a mature specimen might do well in an east window.

You need to acclimate any kind of plant to new conditions, especially such a young one.

There are Kohlerias that take high light - and there are ones that prefer AV conditions. In nature - there ones that are understory plants - growing in a shade of a tropical forest - and ones that grow in an open - usually you can say by the shape of the corolla - if it has good size petals, it is a shade lover, if it is a tubular blossom practically without petals - sun lover. In culture we have all the kind of hybrids - mixed heritage - usually dark leaf Kohlerias requite more light than paler leaf ones.

An old but very good hybrid Kohleria "Jester" can take sunny window and bloom its head off non stop for years. Skorched leaves - from too much light - is just a cosmetical damage. You move it to the more appropriate conditions - and it will pick up no problem. But if a grower tries to fix the problem with more watering - that can be a death sentence. The soil should be light, humid - but never soggy. The good part - these rhizomatous plants put underground rhizomes - so even the top dies = they resprout. But the baby plant didn't have a chance to put a rhizome.

They are easier to grow than AVs. So - try again.

thank you so much Irina this is really helpful! I've had a hard time finding much info on Kohlerias and I run into a lot of general advice articles that don't give much specific info.

The one I have is "Clytie" not sure if that's a sun lover or shade lover?

I thnk it is in-between. probably needs twice more light than AV. If you grow your AVs under the light - put the plant stright under the tubes. If you do not use lights - windowsill will be good too as long as it is not direct South. If you are lucky to have a direct south window - your 'Clytie' will be happy a couple feet away from the glass or if you can use a sheer curtain between your plants and the glass. They do grow well in self watering Oyama pots with the AV soil with added 1/3 of perlite. I use a bit more complicated mix - a half inch of perlite on the bottom, 1/3 of coarse perlite and 20% of milled sphagnum moss in the soil - it works better for all myu tuberous and rhizomatous gesneriads - plenty of air, loose mix - and moss keeps the soil humid.
