    Just for fun - RH and temp for CPs

    Here is how the RH and temperature (degC) changed from 4 Feb to 8 Feb, in hot and humid Singapore where I live. The readings are recorded by the datalogger every 10 minutes.



    Genera of CPs I grow in above conditions
    Dionaea
    Nepenthes (lowlands and some intermediates)
    Sarracenia
    Cephalotus
    Byblis
    Drosera (tropical, some Pygmies and petiolaris complex species)
    Utricularia
    Pinguicula (Mexican hybrid)
    Brocchinia
    Heliamphora (minor)

    Ok, this would make more sense...

    Starts from 4 Feb (21:35:28) and ends 8 Feb (15:35:28). Lowest RHs correspond to highest temperatures.

    Very healthy looking plants, Cindy. Do you grow these out of doors in natural sunlight? (With the exception of N. adnata.)

    Hi Mark,

    Thanks! All the plants are at my balcony, exposed to natural sunlight but sheltered from the rain. N. adnata receives natural sunlight too but the breadbox is at a more shady part, without direct sunlight. Yet last December, I had to change all the breadboxes as they were degrading from the UV in sunlight...If I could get the glass version of them, I would.

    Thanks for the reply, Cindy. Here in the northern temperate zone in which I live the possibility of growing beautiful Nepenthes plants on your balcony is a beautiful fantasy. 'Nice to see it done!

    N. rowanae also grows well in my conditions BUT I have lost 75% of the plants to scales during the wet and gloomy months. The only species to be affected by scales to such a great extent here. Nothing works...pesticide, no...systemic pesticide, no...sigh...




    Next, the Sundews that do well in Sauna Singapore. Tropical ones and petiolaris complex species.

















    D. prolifera (these will melt when the cool night temperatures go up by 3-5degC)

    I really like the tubby pitchers on the N. rowanae plant. Sorry to hear about the scale!

    Ahh - petiolaris sundews out of doors
