i have a D. filliformis and D. rotundifolia. about 3 months ago i thought i killed the D. filliformis, as it had died back virtually over night. i knew this species went into dormancy but on a 13 hour day cycle and average house hold temps i thought that explanation was impossible but sure enough there was what looked like a dormant bud so i took it out of the regular Drosera tray under lights and threw it up in a window. i checked on it today and low and behold new growth after three months. soooooooo since day length and temps arent what kicked it into dormancy do these things have internal clocks? my D. rotundifolia also went into a sorta dormancy, its rosettes dropped to half size and sickly looking and did nothing for a couple months but now looks happy and is back to original size. wierd.
