Well that is just one pot that I finally put in the ground a while ago. Its doing better than I expected. The old traps (ones that grew while in the terrarium) are on the ground.
For the soil mixture, I just used straight Sphagnum peat moss. Make sure its pure peat moss and not miracle gro because it has the fertilizers that will most likely kill your plants.
I should have mixed with pearl light for aeration but o well, its doing fine.
It is a PAIN to mix the peat moss with water. the peat moss likes to float/ not mix with water at all. but eventually after you do get it mixed, flatten it and then plant away. It will stay pretty wet for a while. As for water, I've been letting the rain do most of it. I do sometimes go out with a cup of water and pour it on the single plant when it looks a little dry.
The bog is also in full sun, so that helps a lot. When I do plant the rest of my carnies I'll try to get some real sphagnum to keep in the moisture.
In the future I plan on getting a 55 gallon barrel and collecting rain water from off of my roof. Haven't tracked down a barrel yet, that's the only thing that's slowing it down.
