This is a General Byblis (Rainbow Plant) Care Guide - it will be updated later for specific species.
Water:
Distilled, Reverse Osmosis, Rain or water with TDS under 50.
Keep media moist, the pot can sit in water so as to need little maintenance.
Light:
Medium light, these plants should receive around 10 hours of bright light.
Plant should be constantly growing
Temp:
These plants are annuals that need to be kept in tropical conditions to stay perennial, as such should be kept above 65 degrees.
Media:
Pure Long Fiber Sphagnum Moss (LFSM), LFSM + Perlite or Peat + Perlite.
I prefer LFSM + Perlite for Byblis.
