I have a small collection of temperate sundews, pitchers and flytraps. They're outdoors right now and doing fine. When it comes time to bring them in for the winter ( Chicago), I'd like to transplant them into a terrarium, where they would stay permanently. Except for the S. flava which is too tall. I've heard people say that sulfur produced by anaerobic conditions in a terrarium is a bad thing. Is that a universally held view? I've seen pictures of terrariums in which people placed their plants in their pots in the peat layer. Why would they do that? I want my plants to be able to spread out. I'm thinking in terms of LED lighting without a hood.
Get your cursor/mouse pointer over his name. It will likely change once you have it in the right spot. Mine goes from an arrowhead to a hand. Give his name a click the same as you do for any other link. That takes you to his Profile. Scroll over to the right and you will see a button "send message". Give that a click and follow any instructions there. After you send a message the next step is watching for a reply. The top green bar will show a number beside "messages" when the reply arrives. Click that to read it. You can also set up "notifications" to email you when you get messages or there has been another reply on a thread that you are watching/bookmarked. You will find that by clicking "profile" or your own name. grack

Sorry, I'm a newbie. So no advice from here on the pros and cons of terrariums.
Temperate plants should not be kept in terrariums. Most require higher light overall than is provided indoors, and when they go dormant you'll have to move the entire terrarium to a cool location anyway.
I'm pretty confident that I can get an LED system that will give me enough light. Do you think that I'm wrong? Another member told me that dormancy is a matter of photoperiod and that a cool location isn't really necessary. Do you think that he is mistaken?
Light intensity is a strong factor that influences when the plants will go dormant, but as Paul noted if they are kept in warm conditions afterward this leads to death in many cases. And the mentioned book is most definitely a strong source of info.
Hey, thanks a lot. Now my problem is that I don't really have a cool spot. My basement is too warm, the coolest part maybe getting down to 65F, and my garage is way too cold when it gets down to zero or worse outside. I've overwintered herps in my refrigerator, is that an option? Now regarding the terrarium, how about if I stock it with plants that don't require dormancy? Off the top of my head I'm thinking mostly or only sundews. I think most pitchers get too tall. I will get a copy of D'Amato. Thanks
There are some CPs you can get that can grow in a terrarium, but you have to take several factors into consideration: Air circulation is critical How each plant gets watered - some like top wayering, others tray method Light conditions. Most CPs like very bright light. Choose plants that in general like the same conditions, at least in the begining. If you go foe Nepenthes, consider the size they will reach within several years. They don't make happy terrarium plants forever...
I grow in a terrarium of 1 meter hight: Nepenthes Bloddy Mary, halfway high, under 5 T5 36watt lights. Drosera capensis typical, with 3 9watt LEDs 10cm above it Soon to come - terrastrial ultricularia with 5 9watt LEDs about 50-60cm above it.
The terrarium has about 15-20cm of peat/perlite/coir mix on the buttom, half way filled with water. I set up a pump that pulls up water from the buttom three times a day, for three minutes each (from one side with rocks, to allow water flow), and either drips it onto the Nep, or fills up a bowl the Drosera stands in. The ultrics will receive water the same way.
As for putting the plant in a pot, in the peat, that allows the plant to be removed if nessacery, for treatment, photos, if you want to treat the terrarium but not the plant etc... It is your decission if to do so.
I use 10 cm computer fans connected to a computer fan speed regulator. They are placed at opposite ends of the terrarium, and constantly blow a low level breeze, which increases when the temperatue is warmer.
