i just ignore them.......believe me there is lil to no effort put forth towards their care......dont have time for it which is why you often see dead pitchers in my pics, i only clean up my plants once or twice a year....my basement temps are easily controled cause my bedroom is down there and i like to sleep cool at night, lights int he plant room warm it up during the day......watering schedule depends on how often i run the central air but during certain times i dont even have to look at them for 14 to 20 days at a time if im busy.....
as far as the desirable species.....i just grow what i like, there are some highly desirable species i really have no interest in, much rather have villosa than eddy, will pay for a villosa, might take an eddy given to me.....actually dont spend alot on my plants, prolly buy less than $100 in cp's a year....actually get more as gifts than anything, trade for most the others.....every once in awhile i see a nep i want on a price list, cash in the change i save and buy it....
