    there are several others on here who have a rajah, its not a rare plant, just hard to grow...
    Yeah, I got one from you a while back ; and between cool nights and dousing it with espresso, I have real hope that it'll take care of the neighbor's shrieking cat some time soon . . .

    for you, seeing as you have pretty good highland conditions even outdoors, how do they fair and do u find that lowlanders are more difficult for you?

    Also they sell dry ice at publix and other supermarkets like that. not sure how much it is over there tho.

    I've tried a variety of cooling methods including ice, and trust me, changing that ice everyday will get old real fast.

    Most growers probably have a wine celler or basement that stays cool, but I settled for a more expensive option of using a 1/15hp aquarium chiller and a small cpu radiator. It works wonders, the day/night temps are 24/12C, and it can get much colder if I wanted. Without the cooling mechanism, the T5 lights in my tank will make the day/night temps of over 30/24C (night temps is room temp). My tank size is 50 gallons, but a larger tank can probably be used since my chiller isn't even working at max capacity.

    I have also seen attempts with peltiers, but they only do something to very small tanks.

    Of course, the major con again is definitely cost. It will put you back like $500 canadian for the chiller, the aquarium pump, the tubing (from home depot) and the radiator (from ebay).

    chiller and bucket to catch condensation from tubing


    Cooled terrarium. Black thing is radiator with cpu fan. Circuitry controls the fan, cooling only happens with the fan is on so you can do some feedback with a temperature sensor to keep the day/night temps at specific levels (I chose 24/12C).


    And I can't miss an opportunity to show off my rajah ;D (click for larger sizes)

    yea its completely opposite for me thats why im staying away from highlanders, sticking to ll and hybrids. no job, so no way of cost efficiently cooling terrarium down enough for HL.

    And Z very nice rajah. see you just further solidified my reason to stay away from HL. 500$ is too much.
