Tigrinums are one of my favs. I'm sure you will do well with these babies.
INOIQ Hobby? So it is Rhizophagus irregularis. I doubt that this is beneficial for Paphiopedilum. But I wish you good luck!
I am not sure about new seedlings but I agree mature P. tigrinum like to dry out slightly between watering. Also, based on my experience with this species, even a small amount of water trapped in the flower sheath will cause bud blast, so be careful with watering and make sure it dries out quickly.
When I say treat as epiphytes, I mean when you think they probably need water, hold off for one or 2 more days. They seem to go off their roots if kept moist all the time.
