I've been enjoying this thread too. I think there's still allot to learn about the the best horticultural conditions for different Mexican Pinguicula species. I think we tend not to appreciate how much difference there may be in preferences between species. I hope to learn more from other growers experiences, here are a couple of contrarian approaches I have for a couple of species. P. gigantea growing in an all-mineral slightly alkaline media, consistently sitting in at least 6cm of water, grown in highland temps and humidity. P. laueana from leaf pullings happily growing in live Sphagnum.

How did I miss this post! Amazing stuff DVG, I've been debating on adding a part of two peat to my mix for a few species, have you found any species that don't like this? I keep hearing the larger leaved species like it the most. Here is an excerpt from one of the links above ... The plants are further divided into calciphilious (calcium-loving), and calciphobic (calcium-hating). P.gypsicola and P.heterophylla are examples of the former, while P. colimensis, P.cyclosecta, P.ehlersia, P.esseriana, P.moranensis, P.rotundiflora, and P. zecheri are examples of the latter. The calciphilious forms appreciate high pH media (either vermiculite based, or with an addition of limestone or gypsum to the planting mix). The calciphobic species appreciate a standard, acid CP mix like peat/sand. [/I] This is just a rough guideline, and more experimenting needs to be done with each species for each grower's set-up. dvg

Thanks for the links dvg. I would agree thought that they are a "rough guideline", that's why I like threads like this that share first hand growing experiences from a spectrum of different setups and approaches.
I've grown P. cyclosecta in an all-mineral (alkaline) mix for many years now without any issues. I've found that light spectrum more than anything has affected the growth of my the cyclosecta clone. Moreover I've found that P. moranensis can thrive in a number of different media types, I grow mine in an all-mineral mix. One of the major reasons I changed medias was because the root tips of P. moranensis always tended to brown as soon as they touch the peat based media. I find my moranensis plants have much healthy looking root systems now they're out of the more peat based media.

Dvg with that said, looking at your pink moranensis plants in the more peat based mix really inspires me to start growing species/hybrids side by side in all-mineral and more acidic, peat-based mixes for direct comparison.

The Italian Carnivorous Plant Society (AIPC) issued a great article on Mexican Pings on CD a few years ago. Used to be available for order on the Web but the link is dead now Aren't most all-mineral Ping mixes fairly neutral? It's only if you add crushed limestone or dolomitic lime that you get an alkaline mix. In my experience all of the small round pings except rotundiflora prefer mixes without so much peat.

I add a fairly small amount of (well rinsed) dolomite or aragonite sand to my all-mineral Ping mixes as you mentioned Hal, so I assume they're slightly alkaline.
