    Hi to all !!
    Few months ago I asked information on cultivation of Nepenthes out of greenhouse, here are some result of my little experience after the first winter with these conditions:

    -South facing window of a room with direct sunlight
    -natural light (very few hours of photoperiod; about 8 hours in december)
    -temperatures from 16C to 23C (from 60F to 75F)
    -humidity from 70% to 90%
    -misting two time a day

    Some plants stopped or produce leaves without pitchers, I think for the reduction of photoperiod.

    1:weak and undeveloped leaf of January
    2:follow leaf of March and relative "big" pitcher of 1 inch

    Nepenthes veitchii: slow, but without stop.

    Nepenthes sanguinea: last pitcher

    Sorry if the image are large.

    Waiting for comments
    Kind regards

    Are these in a tank or just sitting on the windowsill? If the latter, they look excellent compared to what I would expect.

    Excellent growth. Looks like they need more light...especially the N. rajah..it should have reddish tinted pitchers at least. Might just be a newer pitcher on it too and it hasn't fully colored up yet.

    Heavens, Rajah,
    Where do you live that you get 70 to 90 % humidity during the winter? We're lucky to get indoor humidity above 15% here in the winter! Talk about statick electricity....

    Nice looking plants, BTW.

    Hi Dustin, You're right, but from May I'll put them outdoor in a North position, as last summer, they will take direct sunlight from 5 to 10 in the morning and from 15 to 20 in the afternoon.

    Hi Joe, I live in North Italy at about 300 metres upon the sea level and I live near a little lake that makes a quite humid climate.

    Regards

    Rajah

    Excellent! Very interesting, indeed!
    One thing I noticed from the pic is that you are using some very course materials in your compost. One of those lava pebbles is about the size of the whole N. veitchii plant. Does that work out okay? I know Heiko Reischer(sp?) came out with an interesting article on non-organic compost consisting of lava pebbles, Seramis clay perles and another clay-like perle(maybe Alifor?), but I was thinking the diameter of the components were small.
    I have been looking for cheap lava pebbles of the smallest size. I can get 1-2cm diameter in a good-sized bag for about $3. the tiny ones in a very small bag are also $3.

    Regards,

    Joe

    The big lava rock in the photo lie only on the surface as decoration for Nepenthes veitchii.
    The compost is eat moss, perlite, small lava rock (about 1cm), bark (from 0.5 to 1 cm), silica sand (0.2-0.3 cm).

    Regards
