i recently read that highland nepenthes need good air circulation in a terrarium. is this true? if so, how do you get air circulation in a terrarium without the humidity going down with a glass top?

I have a fan at one end of my lowland tank. I don't know how well it works, but I leave a slight gap at the opposite end for ventilation. The humidity is hanging out around 75%. I'd like more, but the bicalcs seem to think that this works just fine.

I have no idea how to keep highlanders in a closed tank. Do you really need to? I have a couple of plants in an open tank, but that is largely because I needed the rim to clamp my lights to.

i do need to keep them in a closed tank because, the humidity in my house is very low. i'm stil not quite sure i need to have much air circulation because the i have seen a few alpine tanks without. also could i leave the tank open for a minute or so a night then mist alot and close the tank with glass again?

Thanks hottielover14, I have some tropical sundews, a Nepenthes sanguinea, a bunch of baby hybrid Sarracenias and a Sarracenia rubra to go with my Venus Flytraps. I have to grow them all indoors under those 4 40 watt shop light tubes right now. Drosera spatulata clump in 5 inch pot. Drosera adelae forest in 6 inch pot, the progeny that cloned from a single plant about 10 months ago. Drosera capensis, a sundew that gives the term carnivorous new meaning. This plant single handedly caught and ate 7 flies in one day. Drosera graminifolia or, the Brazilian Grass Sundew that gives mosquitos nightmares. Sarracenia hybrid seedlings about 6 months old. Recently repotted, they are suddenly putting on a growth spurt. Still a far cry from the foot or more adult size they will attain in about 4-5 years. Sarracenia rubra about a foot tall. Nepenthes sanguinea recently repotted in 8 inch pot. The roots are only 2-3 inches long, but the plant has grown from 3 inches across to about a foot across with 5 inch pitchers in about 8 months. It is loosing a few older pitchers at this time. Peat moss and perlite would be OK for your plants, however; Nepenthes would prefer a well drained mix of two parts perlite to one part peat, or one part each of peat, coconut husk, and orchid bark, like my sanguinea is growing in. They need very well drained medium that still maintains moisture without promoting stagnant conditions. Venus flytraps would prefer one part peat to one part perlite and damper conditions than the Nepenthes.

Walk-in Closet - Odor and Air Circulation Issue
Q

Thank you very much for the reply. Microban is a hospital grade germicide/fungicide/moldicide. It deodorizes and kills just about everything. It's odorless and very powerful. Google it if you're interested. The Damprid was for excess moisture after saturating the walls with bleach and water. I know that the water can sometimes leave the surfaces damp. The Cinderblocks and wood studs were installed in 2004 along with the slab, so 10 years seems like a reasonable amount of time to cure ;) The other two walls are still up, and the paint is the same throughout. The paint used on ALL the walls (in the entire house) is the same. Behr Premium Plus Ultra - two coats over the original coats. I should also mention that I originally removed two feet of drywall all the way around the room as part of a mold remediation. I can be fairly sure that the paint is not the issue, as the odor is not similar to any paint smell, and I've also used this exact paint throughout the house without any type of odor issues. This particular room is a bit sub-grade as well. It looks like they filled the dirt line outside a bit too high, but the slope is proper. As a precaution, I installed a french drain (corregated slitted pipe w/ a pipe sock burried under rocks around the perimeter of the front of the house, wrapping around the outer walls of this room with a 4" pipe running to a pop-up at the curb) This has removed any water from going underneath the house in the subgrade areas. It should also be noted that the windows are fully sealed all the way around and the stucco is also in great shape with no hairline cracks or leaks. The attic vents are underneath the eaves, but I have no attic access to check them out. any further ideas???

This is the sole REASON the door is louvered. The more air the better. Unless it's in your way.....leave it open or ajar for good measure. I doubt you are doing laundry while you entertain guests : ) " Drying times can be slightly increased compared to vented dryers • The dryers need a little space around them to access room air – they can be installed in small areas like closets, but please note that closet doors need to be open while the dryer operates • Environmental profile: Friendly – ventless dryers are highly efficient because unlike conventional dryers, they recycle the heat they create

Hi johny2008, Have you done a google search for terrarium supplies? There are a huge number of dealers that have fan kits, cooling/heating devices, automatic humidity control systems you name it. I have been searching myself as I am looking into custom building one for some ultra lowland Nep's sometime in the future. But if you just wanted to raise your humidity around your plants, you could do that easily without closing them up in a terrarium. For my highlands I just used a top dressing of dampened long fiber sphagnum moss that I mist lightly a time or two a day, and they are doing great.
Good luck

My solution tends to always be add humidity to the air. In this house, my furnace humidifier seems to work quite well so I haven't been using room ones. Is a room humidifier a possibility? It'll feel more comfy for you as well.

Johny you an still get air movement in a closed tank by having the fan in the tank. My orchids haven't complained and there is very little air exchange with that outside of the tank. I just fans in the tank.
