Hello everyone, yes its probably a stupid question but i am a little concerned for my heli, i grow it in a tank with 400W HID lighting, and my tank has a new cooling system but i am unsure if it is effective yet, but the tops of a few of my heli leaves are browning , i know since it is a fairly new plant its adapting but i hope that i am doingokay with it. My temps are 30 celcius in the day and around 20 at night but now with the cooling system i hope it will go down much further to 12-15 celcius at night, humidity is always around 80-90%RH  any other suggestions on the species? thx vick, |

Hey Vic,
Is this your first heliamphora? Are there more leaves growing from the middle to replace the older leaves?
Generally, Heliamphora only maintain a couple of good leaves at a time per rosette. The other leaves are either fading away or growing.

it seems there are new leaves shooting up in the middle , and the pitchers that are new seem to have a nice nectar spoon at the top , im hoping it will be fine, i have a feeling im just being paranoid, i am sure it is fine, as for temps my cooling system seems to bring the tank down to 19 deg celcius, and 98%RH so i am sure it should be fine, and in the day it gets to 30 deg C at 70%RH so im sure it will be fine, it is my first heli, so time will tell  |

You fail to mention how deep is your tank, how far away from the light are the tops of the plants, how long the light is kept on, and if you are using any cooling fans in the tank.
Reason: the 400 W HID generates 1000 foot candles of light at 3 feet away from the bulb.
Also your temps are running too high. Even though H. minor is a low land species I believe that a day temp of some 22C and a nite temp of 13C are objectives to aim for in your set up.
To offset the impact of the light which I believe are burning the leaves I would use two banks of lights, the HID and a bank of plant gro lights, that are tied to a dimmer switch with the HID being ran for about 2 hours during midday and the gro light being ran early in the AM and after the HID is dimmed out in the afternoon. This is a rough approximation of natural conditions and may be just what your plants need?

I had them hanging on the wall but with a glas plate between the lamps and the terrarium. I had 150 watt 10.000 kelvins. |

hey thanks for thge replies, the lamp is a good 2 feet from the tank i suppose. And the photoperiod is around 14 hrs or so. I do have an airconditioner hooked up now on a timer that runs for one hour once the lights are out and i leave my window open. since it is very cold here the room temps drop to around 15 deg C and the tank is slightly cooler. i think the application of the ac has helped immensly, especially since the key to growth is lowering the medias temps. so overall i think i am on the right trackk. i do have a fan in there that is on 24/7 and im sure that helps as well. The heli has seemed to "purk" up a lot and the new pitcher that just came out actually has a necter spoon! and is colouring nicely. Perhaps i let it dry out too much before. I am trying to keep my plants wetter now. i also have a ceph with the same problems but now that it is wetter it seems far happier. I was always under the impression that since it is from Australia it would dry out esy since it is hot, but im sure in the native habitats they get enough moisture.

Well, it certainly looks happy. The older leaves do fade like that. When the plant grows larger, it will probably be able to hold more leaves at a time, but it is completely normal for the old leaves to fade to yellow and then dry to light brown as the plant removes what nutrients it can from the old leaves and transfers them to the new growth.

any other suggestions on the species? thx
