Heliamphora minor, Auyan Tepui, Venezuela
Heliamphora heterodoxa, Gran Sabana
Both are growing without elevated humidity, next to all my sundews. The minor has been very very slow, while the heterodoxa has been sending up immature pitchers nonstop. You can't really tell at this point that it lost 3/4 of its pitchers after I planted it.
Also I thought I'd share the method I developed for humidity adjustment. Nurseries that ship plants potted tend to put a clear plastic cup on top of the pot to protect the plant. I had a bunch of those sitting around waiting to be recycled and since they're the perfect size for these pots, I thought I'd put them to use. I just cut the bottom off (depending on how tall the cup is you could cut up to halfway up the cup) and then cover the hole with plastic wrap. Then you can poke holes in / remove the plastic wrap as normal, and finally remove the cup entirely. It makes a nice rigid structure so you don't have to worry about bags collapsing on your plant.
The only issue I've run into with this method so far is with a Utricularia calycifida which has grown a flower stalk a foot and a half tall up through the next shelf so I can't remove the cup without damaging it. It's also starting to lift the cup off the top of the pot with new growth. I think I need a bigger pot...
