Ah, interesting. Hoffs should actually appreciate drier conditions, I guess that makes it harder to find a balance.
Yeah it was totally my bad. I use Gnatrol water to keep the gnats at bay, but if I soak the substrate too much, the hoffs start to die off (heck even vulgare die off if too damp). So between letting it dry too much and getting busy with other stuff (ants are more demanding too), I let it stay dry too long. Sigh, very expensive mistake.
And my granulatum actually crashed recently. They like it moister than hoffs by far, and I may have let THAT get too dry too. I still have a bunch left of those, at least.
