UK help for Al's gritty mix
I've been reading through past threads about the gritty mix in a bid to transfer all my succulents over from their current sad state soil but I'm struggling to find some of the ingredients and am unsure about others, as in the UK we seem to have different names for a lot of the stuff. The more I read the more confused I seem to become so I thought I'd do a post in the hope that some of you wonderful knowledgeable people could help.
From what I've read it seems that I can use vermiculite as a turface replacement. Are there better products for this task or do we have turface under a different name? I went to my local garden center but the vermiculite they stocked was in a fine powder so would not work, I saw B&Q and Homebase also sell vermiculite, has anyone bought these? Would they be a suitable size? If not where else can I get it or should I ebay it?
For Gran-i-grit is regular horticultural grit suitable? again would I be able to get this from my local B&Q or need to find a more specialist supplier? also would poultry grit be better as I can get this from ebay?
For the bark I was going to go to my local reptile shop and buy some of their substrate. Has anyone tried these and if so is there a brand that's best? Or is there something suitable that might be easier to get/cheaper (I doubt it but can only hope)?
Also I keep seeing for sale orchid bark, but never information about which tree its from. would this be suitable and is orchid bark a specific mix or at a manufacturers discretion?
For the gypsum is garden lime ok? And which fertiliser would be suitable for succulents in this soil?
Sorry for the long list of questions. I just don't want to splash out a bunch of money only to get it wrong.
Oh and all my plants are grown indoors in individual pots. Mostly I have jades and echeverias, there's also a few unknowns that i'll do another post about once I'm not embarrassed to show how they're potted.
