For all my neps, I use a mix of 1:1:1:1:1 perlite, vermiculite, orchid coco chips, sphagnum peat moss, LFS. When potting up lowlanders I use the same but I use a greater percentage of peat moss. I believe this is ok, the plants seem to be growing alright.
However, I want to create a new mix that improves air circulation around the roots. I wanted to add to my current mix something like charcoal or some sort of bark. I was wondering if the bark they sell for reptile terrariums at pet stores would work. Also, when buying charcoal, Is the charcoal that they sell at convenience stores ok? This is the type of charcoal that one brings home for BBQ's. It is not the nugget type, I am talking about natural charcoal that even looks like little bits of wood, only black hehe. Anyways I wanted to know if these two materials would work. My concern arose because in some of my larger neps that are potted with my current mix, the water does drain out almost immediately after watering, although it drains out very slowly and I was wondering if I should be concerned about this. Alright then, I'll appreciate any advice.... Later!
