    d.ordensis/derbyensis help

    Hi!

    I recently got into possession these 2 beautiful species. They are large size (ordensis 8cm and derbyensis 4cm across). I have a small terrarium where I grow d. paradoxa and d.petiolaris with great success. (Used to grow there d. kenneallyi too before my parent "took care of it").
    The conditions are: 20-25C/night, 30-36C/day. Turbolights-15hours/day. R/O water-tray method (1cm water, replenished when gone). terrarium is covered with plastic foil on the top leaving 1cm gap. Not much air circulation, very high humidity.
    I placed the newly acquired plants in there and d.ordensis' leaves started to turn red/brown from old leaved towards the centre and from tips to the heart. D. derbyensis is not doing anything. here are some pics:

    D.ordensis




    Please someone advice me what is wrong? Are they going towards dormancy? I read somewhere that wooly sdews ( I mean petiolaris group with hair on the petioles) do not like high humidity and can be grown outside terrarium? And that they love sandy drier soil and higher temperatures than e.g. paradoxa/petiolaris?

    Maybe i should remove them under hot strong lights outside the terrarium with no tray with water just damp soil?

    Thanx for your help! :-)

    The woolly sundews like hot AND humid conditions. They prefer a drier, more drained soil than most sundews. Most people I've seen growing them do use somewhat complex heated terrariums to grow them. I'm sure one of them will help you out soon.

    To me it just looks like they are adapting to the new conditions. I do not see anything wrong with them. Only thing I would say is that, for me, a media with more sand in it worked a lot better.

    If you search the forums using my name and "petiolaris" you should come up with a whole slew of good information.

    klasac,

    My conditions now are 27-30C/night, 30-36C/day. Both species are thriving under T5 lights on a 12-hour photoperiod. They are treated the same way as D. falconeri, the water level is allowed to drop completely before the tray is refilled. I use peat and sand mix for all of them.

    Thanks folks!
    When I searched forum for ordensis mostly pictures came out and some advice put in words.... I just wanted to make sure for my particular case. Thanx Pyro, DrWurm and Cindy. I will leave them inside then. The only thing I am going to change is the substrate. They are in peat/perlite mixture. Coming from a very experienced grower, I know this kind of substrate is OK for them. But might be too old, besides I do not like peat in most mixes and use mostly peat/sand mixes just like Cindy because I think they drain better which is important here. I will use a very sandy soil and put them in larger pots.
    Thank you for your comments! :-)

    LOL! No Perlite? Seriously, your temps and photoperiod are exactly what my min-greenhouse setup is like. I thought D. falconeri likes the media to be more moist, though. But then again, I've killed the few plants I had.
