Thanks for the lesson. I don't grow pings but that's great information.Benurmanii wrote:I like using my 1:1 ratio mix of vermiculite, pumice, perlite, sand, and lava rock since it makes a good consistency that isn't so rocky that water isn't held well but not so dense that creates and anaerobic environment or one too stuffy for some Mexi Ping roots. I find that eventually, moss finds its way into anything. I think the main issue with peat is the bacteria and algae that accompanies it, which make be stealing some minor nutrients from your pings, making them lose color and vigor. The Pings that I sometimes see in culture which have really pale coloration often are accompanied by algae.
I don't always use agricultural lime and gypsum in my mixes. I have mixed feelings about it too. First off, it means I can't put mixes that use it in with acid loving Pings. Second, it can sometimes reduce the drainage of the mix if I put in too much, or it simply dissolves and washes away with too little.
Chemically, I don't believe gypsum nor calcium carbonate would affect your color. Carotenoids and anthocyanins don't contain the ions that gypsum and calcium carbonate create, so I don't think they closely relate to the production of these compounds (perhaps they are used by some other process in the production of these compounds? I am not sure, but then how would other CPs produce these compounds?). I have read the calcium carbonate helps strengthen the cells of Pinguicula, which makes sense to me.
Either way, I have found the most important part seems to be creating a relatively homogenous mixture that holds water well on its own. Plants I have in lazier mixes where the top dries easier than soil farther below it don't seem to do as well as those in a good and consistent mix.

As time went on, I decided that they were worth having for themselves and bought a few more. Mostly I kept them in the NZS - which they seemed to be fine with. Then I started to read and realized that they must be secretly unhappy, so I started to try other mixes. At that point peat didn't work for me - it always got funky after a year or so. Anyhow, when I wanted to expand my mexipings after the Great Spider Mite Apocalypse killed off significant numbers of my orchids and VFTs, I spoke to Ron West (Cascade) and decided to try an all-mineral medium. Right now, they're all in a 1:1 Turface:Gravel mix with maybe 5%-10% Aragonite for flavor. The gravel is polycoated aquarium substrate, so it should be the pretty much the same as silica gravel/coarse sand (which I can't find around here). Most of the mexipings seem to be okay in this mix but there's always a few unhappy ones. I'm still learning.

I considered iron oxide but had trouble forming out 18 bucks for a box of it, for minuscule amount I’d end up using. I suppose if I let some nails rust in a jar of water and water with it, I’ll be doing the same thing, right?

You got me curious. I checked Ebay and you can get 1 oz of red iron oxide for $4 or $5. (I just ordered one.)
