    Hi all,

    I've always wondered how much sense it makes to adapt the lighting period to the internal plant clock. Never have I seen one of my plants adjusting to lighting periods which were differing from its internal clock. Leaves usually unfold around 8am (it actually takes about 3 quarters of an hr to open fully) and about 12 hrs later, depending on plant species, leaves fold again. Therefore, I adjusted the light timer to this behaviour as to allow for maximum energy production.

    Does this make sense? How long does adaptation take for imported plants from other time zones?

    Regards,
    Detlef

    I agree to watch the plant's behavior for light times.
    Mine fold up depending on species, Myriophyllum's, Rotala's, Cabomba's etc all close up sooner than 12 hours for me, often 7-10 hour ranges after the lights are on.

    I stick with 10-11 hours of light therefore.
    I bet I could get away with less.

    Regards,
