Have been battling with whether getting a Terrarium is worth it for Pings? Im probably going to repot my pings into a more mineral based mix. (Im thinking probably the APS and Terfus, or a Mix of either one of those with Sand).
I actually prefer the look of it (based on what im seeing in other people's pictures) and it makes me worry about root rot less.
However, my humidity isn't great in our house, it sits about 39-45 ish most of the time. In Winter it can get down to low 30's in our house (Due to running the heat). Im in an open air setup, so I don't think misting would help.
I also am running very TALL pots right now, probably too tall (They are 5.5 inch tall pots, I've seen suggestions that maybe 2x2 pots might be better?). If I change to a more well draining media, I wonder if the water level (1.5 inches right now) would be able to reach it. Otherwise I might try top watering (Since it seems like Pings seem to sorta like being a little dry perhaps)
Anyways, i've gotten off topic: The Terrarium: I planned on getting maybe a 30 gallon sized one with my 2 foot long/4 bulb light over the top. With maybe using an Egg crate to push them closer to the light (otherwise they'd be around 14 inches away). With a higher humidity I probably wouldn't need the tray method I would think as much, and be able to top water when things look dry.
Or is this not really worth it for the Humidity? (Im also going to grow sundews with them as well for reference.
