Actually, I'm not on here much myself. As for dormancy, I'm well aware of what it is, no worries. The fly trap I have sold, anyway, as the tank is FAR more full now than it is when I took that picture, and I needed the room. And even then, I have some Cephalotus and perhaps some other things that I need to sell/trade off for additional space. The tank will also be upgraded to a 75 gallon soon, with 2 x 130W 6500K PC lighting (I'll post pictures when done...probably not until after the New Year, though. I'll try to get some pictures of the current terrarium today or tomorrow. I've let some of the plants get a little out of control, and it's not as clean as I'd like, but so be it.

Speaking as a Biology teacher, your teacher is unfortunately incorrect. As has been pointed out, sealed terrs are typically very problematic in large part because of the issue of stagnant air. Few plants (or animals for that matter) do well under such conditions and fungi -- including pathogenic ones -- thrive. Furthermore, vfts are EXTREMELY poor terr candidates for a number of reasons: 1) They are very high light plants ... even up to full sun. In a terr it is difficult to provide that kind of light intensity without raising the temperature to lethal levels. 2) Vft's like to send their roots quite deep. This would require a fairly large terr. 3) Most significantly, vfts REQUIRE a chilly/cold winter's dormancy to maintain health/vigor. Without it, they weaken and die -- though they may survive for two or three (maybe four if you are very lucky) years before finally kicking the bucket. Unless you plan on giving the entire tank a cold dormancy or digging the vfts up to do so, they are better off not setting a root tip in a terr. Now having said this, some cps can be done in a "sealed" terr BUT it will require the inclusion of fans for air circulation and a rather large tank too. I say "sealed" in quotes because while the terrs in question are left closed for periods of time they are by no means left closed permanently. People I know growing Nepenthes, for example, this way, do open up the tank every day or two as they check on the plants and allow an exchange of fresh air. It is far easier to go for a partly sealed tank setup (still using fans) as one can keep humidity levels up while allowing for some air exchange. With such a setup, there are a number of cps -- pinguicula, utricularia, and drosera -- that could be used. With regards to the ant idea ... The concern regarding ants harming the plants is not terribly likely unless you were to obtain species that -- like the leaf cutter ants -- actually use vegetation as a food source. However, the issue of wet, stagnant conditions would prove detrimental to most ant species. Also most ant species are carnivorous or scavengers. So you would have to have present a renewable prey/food source for them. And unless you did have a very well sealed setup, you would in all likelihood have ants touring your room and/or home. (And I suspect your parents might object to that. )

I think those biodomes for the Nepenthes Lady Luck plants are in what is essentially a net pot. They sit in a container with exposed soil/roots that take in the water directly. Supposedly the root ball has the fertilizer or nutritiion the plant needs for up to 1 year, so you just have to keep adding water to the bio-dome for that time period. http://www.borneoexotics.com/bio-domes/faq.html

I stopped at my local Ace Hardware today and of course I took a look at their plants. There was a table with several CPs but none had tags. There are 11 species of these plants and some look very similar even to me…and I've been growing CPs for 20 years. A sales lady heard me comment on the lack of tags to my husband and she volunteered that they were Cobra plants and Venus fly traps. NOPE! NOT EVEN CLOSE!!!!!! They all were north American pitcher plants (Sarracenia). She insisted even after I explained the difference and my experience with these plants. And to make it worse they were potted in regular potting soil…CPs are bog plants! They grow in water. I felt so sorry for them. The moral of this post is unless you are buying "regular" plants at Ace (and these all have tags) stay away from CPs and orchids for that matter (same problem with these…no tags and wrong info). BTW if you ever want to grow these amazing plants consider buying them from the most recognized and respected grower in the USA. https://www.californiacarnivores.com/
