I need some people with experience to give me some advice. I recently changed to Schultz APS with a bit of sand mixed in for my mexican pings. Though a couple of them seem to be doing just fine, many others look average at best. Right now I am watering them on the tray method once the tray dries out, but I noticed that at times the APS seems to dry out much faster than soil (this makes sense).
That being said, my first concern is watering. With APS, should I be only top watering, or is the tray method ok? How do I know how much is enough water?
Second, I have never been through the succulent phase with mexican pings. I hear mixed advice; some keep them wet year round while others reduce watering. Which is it and when should I start changing the way I am growing them (if I need to). Just for some brief information, I have them growing under 6 T12 bulbs on about a 15 hour photoperiod. My sundews and nepenthes are thriving, but most of my mexican pings seem to be struggling. I thought they were supposed to be some of the easiest to grow!
