I've had some pygmies now for about a month, they grew from gemmae.
They have seemed happy and grew quickly to their present state. But they appear to be in decline now. I'm wondering if I have been giving them insufficient lighting as it is less lighting than I typically have given my other sundews. Here is a photo of some browning I'm seeing near the base:
The thing is, they're not in a poorly lit spot. I have them in a 6-inch pot sitting at the bottom of a ten-gallon tank. The ten gallon has about two inches of standing water in it to keep it high-humidity (currently there are two small Nepenthes and two small pots of adelae in the tank that are thriving). Atop the tank there are three t-8 bulbs (small). The temperature is a steady 80 degrees and the humidity is a steady 75%. All in all the pygmies are probably about 8-9 inches from the light source.
My other sundews do receive vigorous lighting (6 t-8s, just inches from the light), but I just never put these pygmies under the same lights due to restraints with room.
