I beg to differ about rajah. We grow them here in Taiwan under "fake intermediate" conditions, which means offsetting the tropical heat with lots of shade. As long as there is at least 5 degrees temp drop at night, lots of humidity, and an airy soil mix, rajahs grow just fine.[b said:Quote[/b] (phissionkorps @ Oct. 14 2006,9:09)]rajah and villosa are good examples. The difference between highland and "ultra highland" is that most highland can do well in intermediate conditions, while ultra highlanders "must" have constant high humidity and their temperature range must be strictly adhered to constantly. They are just...picky...i guess you could say
Then why did you ask about ultrahighlands?[b said:Quote[/b] (JMurphy97 @ Oct. 15 2006,2:39)]I'm not getting into getting some of these ultra's like rajah and villosa. I'm just trying to make a hamata a little happier.
Actually , a heat pad can benefit during the day is your temps are low to begin with. If you have 65 degree temps during the(especially in the Winter), that can simulate a temp drop right there.[b said:Quote[/b] (dlybrand @ Oct. 14 2006,10:26)]Don't use a heat pad for ultrahighlanders since they don't need anything far above 75°F during the day anyway. Using a frozen water bottle is not too effective and a big hassle.
Many people use chest freezers to grow these, but the best method is to convert a refrigerating unit to work for a terrarium. Unfortunately, I don't really know how to do that.

Don't bother with the frozen water bottle-- it just sucks humidity out of the air. Besides, with a hamata, you really don't need huge temperature drops.[b said:Quote[/b] (JMurphy97 @ Oct. 16 2006,10:54)]and the frozen bottle goes in.
