Just thinking out a loud, maybe this would work. From my very old thread
https://forum.petpitcher.net/showthread.php?t=1911
How it works
1) The pot will create a local humid area
2) Bottom of pot is sealed, except 1 hold (extended the hole with PVC).
3) For aquatic plant, I plant it direct into the soil. I guess for pitcher plant, I will have to pot it and place on top of the water level (raised slightly)
Downside
1) Pitcher plants are much taller
2) Light may not reach the bottom part easily.
