I have heard lots of people swear by the vermiculite/pearlite mix but I
don't use anything close. I just get standard greenhouse trays and put an inc
of stone at the bottom for drainage. Then I put down a layer of mulch.
Since there are large gaps in the mulch I put a layer of 50/50 peat sand
down to level it off a bit. I just plant the plants in the trays and they
grow like crazy. Most are coming out of dormancy now and I don't even
think any of the pings need to be kept dry during dormancy. My P. gypsicola
plants don't seem to care anyway :) I grow them all under shop lights and
most are varying shades of pink or dark green. I wouldn't mind aquiring
more of these fine plants and if anyone is interested in trading, please

I previously had problems growing mexicans and this works very well for me.
If anything needs further clarification let me know and I hope this helps.
Take care & keep on growing,
