I've found this bladderwort to be more challenging to grow. I grow it in a 4 inch orchid basked, sitting in a saucer of water. I keep it sitting in about a half inch of water, letting the water evaporate before refilling but never letting the media go dry.

I've had issues with powdery mildew with this plant. It shows up as a thin white coating on the surface of the leaf. It can cause the leaves to be malformed. I've treated it by simply wiping it away with a damp paper towel and increasing air flow with a fan.
