myself I use Dynamic lifter ( chicken poop ) on some of my orchids diluted with water like a weak tea mix I soak the Dynamic Lifter for 24 hours before use
then strain the mix before use.
It does stink a fair bit though.

I also use Dynamic Lifter on my Cymbidiums also I just place the pellets in a small pile on top of the medium and with each watering I spray the Dynamic Lifter as well.

I would not recommend doing this inside the house
