ProMix BX soil mix

[jrmc114064]

I am going half on a bail of ProMix BX and was wondering if it would be possible to use as a soil mixture for a cephalotus. The ingredients are:
• Canadian Sphagnum peat moss (75-85 % / volume)
• Perlite -horticultural grade
• Vermiculite - horticultural grade
• Dolomitic and Calcitic limestone (pH adjuster)
• Wetting Agent
• Mycorrhizae - endomycorrhizal fungi (Glomus intraradices)
The company product page is:

Thanks for any advice you can give....

The limestone is added to counteract the peat, to keep the mix more on the neutral side, but I'm not sure how cephs would react to it, same goes for the vermiculite, as it's somewhat alkyline.

Yeah I was originally worried about the limestone as well but need to know its affects on the plant.....
