Hi,

I bought a nepenthes bicalcarata which I received and repotted over a week ago. I nearly killed it in the first 24 hours by placing it on a sunny windowsill, not knowing it was extremely sensitive to sunlight. The leaves and original pitcher burned and turned black.

Since then I've made many adjustments: I put it inside a dome allowing for about 50 to 60 percent humidity, in a place where the main source of light is an LED grow light.

There's still some green remaining on the leaves suggesting the plant is not dead, but it hasn't tried to produce new leaves at this point.

Should I expect that it will recover? If so, how long does this species take to recover from stress?

It's been 2 months and my bical is still just some sad partially-shriveled green leaves (it got shipped to me during a sub-zero winter storm and the box wasn't sealed properly :roll: ), and it doesn't look much better than yours, but at least it hasn't gotten worse! My goals with mine are to just let it do its thing while protecting it from fungal infection. Airflow is the best way to do this (though it might be difficult with a humidity dome), and I very occasionally also apply a fungicide, and use mosquito bits in my tray to prevent fungus gnats from worsening the plant's condition.

Given the optimum temperature (27C) and humidity (70%), should see improvements 1 month after going through stress. At least the grow tip. Bical is not the slowest in adapting to environmental changes. Even stem cutting would show sign of grow after 1 month.

Update. My plant is now growing a new leaf! However, the end of the leaf where the pitcher develops looks black and the pitcher part looks like a white tuft. Is this normal or did the leaf burn up from my artificial lighting?

Highly unlikely your LED lighting is burning a leaf ... especially one grown from the get go under one. LED's don't put out a lot of heat.
