    Thumbs up

    I rotate the photoperiod between 16 hours in summer, 12 in winter. Halfway between seasons I add or subract an hour.

    I used to place some of my Australian Drosera/Utrics on a 15-9 hour photoperiod, but since changed that because I really don't care anymore and they do just fine on the 16-12 hour daylength.

    Hi All! Well, since I live in Chicago and have an apartment, I have no choice but to place my plants in a terrarium. I have a timer in which I adjust to mimic the photo periods of nature's seasons. Most timers have increments of 30 minutes in which you can adjust the times. For the months with an extra week, I just skip it and follow through with the tables. I modfied the dates from last year. It is as follows:

    2005 PHOTO PERIOD TIMETABLES

    I can't use a timer, since, to do that, we'd have to move the stupid bookshelf out six inches.. anyway, my fluorescent stays on usually from approximately 9AM to approximately midnight (whenever my grandfather goes to bed, I dunno.. he turns it off, since he goes to bed way after I do, so that way the plants can get as much light as possible).

    I don't use any light cycle. My plants are in a south facing window in my computer room. They get light from sometime in the morning to whenever I turn the light off and go to bed. That can be anywhere from 10:00 pm to 1:00am and sometimes later.

    That works great for some plants, but here in the frozen north, Neps don't take those dark winters very well. The first year i had them thought my ventricosa, sanguinea, and alata (Luzon) in my windowsill were all sick. Now after a couple boom/bust cycles coinciding with the seasons, i've seen how big a difference that photoperiod and intensity can make.

    The neps explode into new growth in the summer, but lose all their pitchers and don't do much of anything in the winter. It makes for rather weird fluctuations in pitcher size when looking at the plants.
    There's no 'a' in perlite.
