I DO mind, so I'm not going to tell you. Too bad.
j/k...no problem
Soil: 1:1:1:1:1: peat/sand/perlite/vermiculite/lava rock or pumice. The lava rock is optional and not practical for a small plant. If available, add pinches of dolomite and/or gypsum. DON'T soak the mix when mixing and don't compact it into the usual brick--it should remain very open--your plant will thank you.
Light: Will this be in a terrarium? Where I live, growing P. moranensis in a terrarium is a space-waster, so most of mine are on windowsills in full sun. However, I'm careful not to let them fry during the summer, so I sometimes use refrigerated water or provide light shading.
Watering: Don't let it sit in water for very long. Instead, frequently water overhead. When it comes watering mine over the growing season, I kind of treat them like Nepenthes. Weird of me, eh? When, instead of the slimy carnivorous leaves, it puts out the succulent winter leaves, water less frequently, keeping the soil slightly moist. When it starts to put out summer leaves again, don't immediately resume the heavy watering of the growing season--wait a week or two because otherwise, the roots may rot.
This guy doesn't need high humidity, especially not in winter.
If in a terrarium, 70F is fine while in growth; during dormancy, a cooler temp. is preferable.
Fertilizer: I do not feed anything solid to P. moranensis--it catches lots of gnats on its own. If I did, I would use rehydrated freeze-dried bloodworms, sold in fish/pet stores. HOWEVER, while in carnivorous growth, I lightly mist monthly with a 25% solution of Epiphyte's Delight. This seems to be a huge benefit to Mexican pings. BTW, I remember reading somewhere that ping flowers are marred with nasty white spots if fertilizer hits them--so be careful.
(WARNING to people lucky enough to grow P. laueana and have decided to take my advice: I do not grow laueana, but fertilizer (at least MirAcid) has been found to fry lauena's foliage. Avoid fertilizer in this case. Contact me for more info, if you want me to dig up the CPN article that says this.)
Repot every two years or so.
Additional questions are welcome!
