Welcome to the forum, Cangranmafixit (no relation of Jimmy Savile, I hope) ....I haven't a clue to be honest, but did find this via google:
Any carnivorous plant compost will be fine, even pure moss peat, though a bit of lime free sharp sand will give extra body. Trumpet Pitcher compost does contain Perlite ? the small white balls, which can look a little unsightly at first but soon blend in. The way to calculate how much you need is to work out the volume. Compost is measured in litres so you can just see how much water it will hold. Fill the containder to 50mm (2") below the top. This makes watering easier. Another aid to watering is a length of plastic pipe sitting vertically in the container 50mm (22) from the bottom. It should finish just proud of the compost and can then be used to water and to checlk the water level in the container. Evaporation can be reduced by mulching with good quality pine bark."
