I doubt it would work well right out of the gate. Many years ago now, Steve Doonan, an expert grower, did a lot of experiments with coir. Most coir he bought had a lot of salt in it and had to be repeatedly soaked to get the mineral content down to a usable level. I believe it took him something on the order of 10 rinses with rain water to get the PPM down to where it wouldn't kill the flytraps. And even after that, the pH of the coir is a little more alkaline than flytraps like, so they didn't grow as well in the coir, though they did grow and survive. If at all possible, try to track down a bag of sphagnum peat.
The most common one used is live sphagnum. For larger flytraps, it works well. For smaller flytraps, it can outgrow them and crowd them out, so it might need some maintenance to keep it cut back around the flytrap itself.
This is fantastic information, thank you! Since I already have the coir and its literally been doing nothing for 3 years I will take a small portion and soak it. I will measure tds and ph and see what it looks like. I will have a very small margin for giving it up, but if its good to go then I will try it. Otherwise I will see about getting something more traditional delivered.
live sphagnum sounds like a good option.
I was thinking of setting up some pvc in my pot of choice so that the bottom can fill up with water before it overflows out the pvc drain. Plan was to put the top of pvc drain something like 4" from the top of the pot. That way water could be stored in the bottom of the pot but the pot itself could never overflow as it would always flow out the pvc drain 4" from the surface. (does that make sense?) Is this a good way of doing it? Should I set it up so that its closer to the surface then 4"?
I see a lot of folks using little saucers to hold in water but I prefer not to go with that option if possible for aesthetic reasons.
Another question, I live in Maryland in zone 6B. For over wintering I have 3 options. Leave the pot in place on my porch (full sun 7-9 hours a day depending on season) and just mulch the top. Put the pot in a garden shed (no heat, away from the house but has 4 sides and roof). Put the pot in my garage (one side attached to the house, doesn't freeze or if it does, not by much). Which is best? Outside it will get rain water, whereas the other option relies on me remembering to water... which I might....
