    I purchased two Heliamphora hybrids about 5 months ago. They are growing outdoors in Honolulu in partial shade under the same conditions as some lowland/intermediate Nepenthes. One is H. heterodoxa x minor, and the other is H. heterodoxa x ionasii. Both are small plants with pitchers about 2 in. long. Both are growing in LFS, top watered every other day or so, so the medium stays moist.

    The H. heterodoxa x ionasii is surviving so far. There are no more pitchers than when I got the plant, but the pitchers have grown larger.

    The H. heterodoxa x minor pitchers were staying about the same size, and new pitchers were replacing the old ones that died. So in the beginning it was in a holding pattern. However, a couple of months ago I noticed that the new pitchers did not have nectar caps, and in recent weeks the pitchers have been dying off faster than new ones have been growing. There are only about 6 pitchers left (it started with about 15). I figure itís because the weather has been getting too warm because summer is approaching.

    The high temperature during the day is now often in the high 80ís, and the low at night is in the mid-70ís. (The relative humidity is in the 70ís or 80ís, so that shouldnít be a problem.) I think the plants, especially the H. heterodoxa x minor, might need a cooler night temperature. However, that would be difficult to provide. Anyone have any thoughts on this?

    sound like they are jsut getting used to our setup, should be fine although there are probably a few things you can do to fix this, first higher humidity sounds like an issue, if you are haveing trouble with this, try growing them in ziplock bags, second of all, cooler night temps as you said, these Helis are from Venezuela, and like temps around 60 at night, with high humidity, I dont know how to achieve cooler night tempuratures except take it in every night with would be no fun, thats all I have to say

    I'm 0 for 2 in growing H. heterodoxa x minor.
    From what I have found out from asking questions here, it seems I watered mine too much and cause the plant to rot both times. I watered mine twice a week the same I do my sundews and sarrs. If I get to try another one I will be watering it less like I do my cephs which grow great,

    They need as close to 100% humidity as possible

    My H. heterocoxa x minor is thriving in a terrarium with the following conditions:

    80W fluorescent lights (6" under, 12hr photoperiod year-round)
    >90% humidity
    75F daytime, 65-70F night
    good air circulation with CPU fan
    1:1 peaterlite mix
    Always kept moist but not standing in water
    Fed dried crushed insects once per month and foliar fed with diluted orchid fertilizer at same time.

    Hope some of this information on growing conditions helps. Good luck with your plant.

    maybe for the heterodaxa or minor, but I have H. ionasii growing outside on the deck. Humidity fluxuates, it get watered when it rains, etc. etc. During the winter it's in my highland tank, and I do let it get fairly dry before waterring it again. I'm not sure that's a good thing, though.

    At any rate, at least for ionasii, the idea that it needs REALLY humid conditions is exagerated at best.

    Well they seem to do fine in those conditions the H.. heterodoxa also. Anyway Tropics if the soil is as nutrient poor as in teh wild you will only have 2-5 pitchers on a plant at a time anyway except on a couple species. I doubt this is true in your case. What do you have them potted in?
    I think maybe they need to be in intermediate to highland conditions. This could be accomplished by leaving them outside in the day then covering the pot with a plastic cup or some water tight containter and bringing it in side at night.

    What kind of water are you using?

    Also, I find that plants in dark pots will heat up when the sun hits them. If you can shade the pots, this would help keep the roots cool.

    I find that Helia's grow very well for me if I can drop the evening temperatures by about 15 deg F.

    So, make sure your water is right, (RO, distiled, rain) and shade your pots...
