Reddit reviews GE 46676 - F14W/T5/865/ECO - 14 Watt Fluorescent Tube - T5 Fluorescent - 6500K - 800 Series Phosphors

Sorry about the length of the post but this is information I wish someone had given me when I was starting. Hopefully it's not too basic.

I am by no means an expert but I can walk you through my trial and error period (which I am certainly not finished with) for terrariums. I don't know that I'll be able to help with the nepenthes though discussion in this thread indicates that humidity is key for those plants. I am seriously limited on space where I currently live so I've developed a setup that seems to work for my plants, though it's not ideal for all of them.

Initially I had been growing my plants on a windowsill but this summer I moved to a location that has proper shading over the windows (great for people, terrible for plants) so I needed to migrate to a terrarium. I started caring for plants in May so I didn't really know what I was doing. If you haven't already, I recommend purchasing The Savage Garden: Cultivation Carnivorous Plants by Peter D'Amato. It's a great introductory book with lots of useful information about growing and indoor/outdoor setups. You can find it on Amazon for a moderate price.

I ended up purchasing a 10 gallon aquarium from PetSmart or PetCo for something like 30 dollars. The box was damaged so I got it for cheaper than whatever it was listed for. Those come with a water heater for fish which you can place in a bottle of water inside the aquarium to increase humidity if needed. I then bought some Plexiglas and melted holes in it with a soldering iron for ventilation. I used that instead of the lid the aquarium came with so I could use more lights if I needed to. I mostly have sundews so I opted for a 2' t5 light set up which can get pretty toasty, but my sundews loved it and it got very humid inside. I use four of these lights for ~5000 lumen output. You would probably want to go with t8 lights as they operate at a lower temperature. Do not purchase lights branded as "growlights" as they are almost always more expensive than similar lights and will not last as long as something from Phillips or GE. Like UseUrLogic said, use lights with a color temperature of 6500 K or higher. I find that 6500 K is the easiest to find and work fine.

I do have two flytraps and they were not happy in the aquarium, but they were still growing. I imagine one of them would have died had I left them in such a humid environment for any longer. I then moved again and needed a new setup, since I didn't want to kill the traps. I'm now doing something like this but much more jerry-rigged. My plants seem to like it though. You might consider something like this as my flytraps love it too. I'm going to try taking them outside soon in an attempt to have them go through natural dormancy. I may just give in and try fridge dormancy though I have heard mixed results.

I was bored so I looked up some information that may be useful to you when deciding what to do with your plants. Most of the is from The Savage Garden.

It behooves you to find out what your pings are, as different species can have radically different growth requirements. Consider posting images here or on the ICP forums if you can't ID them yourself. Here is what Peter says about pings in terrariums: "Forget temperate varieties here. some warm temperates do nicely, sich as P. lusitanica, P.caerulea, and P. primuliflora, but do best with cooler winters. Most of the Mexican species thrive under grow-lights, in a tank or not, at room temperature. Use the pot-and-saucer method to allow for drier winter conditions."

For the cephalotus he says "Excellent as a potted specimen year round in the unheated greenhouse-style terrarium. Colorful and vigorous under grow-lights." He also says it should be fine on a partly sunny windowsill in relatively high humidity and that you should mist it often.

The Nepenthes maxima (Highland Nep.) is apparently a good terrarium plant and easy to grow, though it likes good air circulation and misting at night. The truncata is a lowland variety and apparently will do well in a steamy terrarium. Both of these varieties will eventually outgrow all but very large terrariums.

The only plant you own that I have personal experience with, other than the flytraps, is D. Aliciae. Unfortunately I overfed mine shortly after getting it an it died back to the root. It's coming back now but it won't be as big as it was before for a least another two months. I've found that it's a pretty hardy little plant. It can handle temperatures of up to 95°F and down to ~40°F (though that's pushing it). I currently grow mine at ~85°F. It doesn't need much humidity at all (I was growing it in 50% and it's now doing quite well in about 35-40% rh) but growsundews.com recommends humidity over 60%.

Good luck with the plants!

TL;DR "UseUrLogic" is correct in that you will not be able to keep them all in the same terrarium. You may be able to start with all but the flytraps in but then I recommend migrating the pitchers to windowsills and misting often. Try to find out what the pings are. Maybe consider a setup similar to Bisnick's as it will accommodate your pitchers even when they are larger, though it will require a larger light setup.
