I found these two items on the rePotme.com site. I am wondering if anyone has used them in their potting mix or is it best to just stick with Perlite.
On that note, do you use small or medium perlite in your mix? I have been using small, but it is very dusty and I am thinking of trying medium. I also use perlite in the bottom of my pots with a wick up through it and laying on top before the potting mix.
Here are descriptions:
Stalite Slate is an all natural medium mined in the United States from volcanic slate which is then rotary kiln fired to over 2000 degrees. The material is then made into sterile granules or pieces that are extremely porous and PH neutral. It has the ability to aerate and also hold moisture/nutrients for orchid roots to seek. Because it is essentially a type of lightweight rock, it is extremely durable, and will not compress. It has low absorption yet the pores store vital moisture and nutrients for uptake. Picture a sponge and then turn it to stone with all the spaces, holes and crevices retained.
Aerolite is small foam polystyrene (trade name 'Styrofoam') balls that are used to increase aeration and reduce moisture retention in a mix. It is often a component in peat and seedling mixes.
