Making Mix! Need Feedback

[Matorchid]

Hello all,

I was wondering about mixes and have read certain threads about densities of mixes.I wanted to make my own that might work for my Dendros, Zygos, Paphs,and hopefully Oncidiums. I know all these like the more finers and smaller product we all get. I typically get my mixes through a very reputable company, but just wanted to experiement a little, plus it seems that most of the mixes are very coarse and this hasnt workedso well for me. They just dont seem to hold plant well, hence the experiment to find a smaller finer mix that works well with thses kinds of families. I do know most all of plants that fall under the ones I just mentioned like to have a damp not soggy media.
So I know alot of whats in this mix may be (will be) over kill, but still intrested in everyones opinion before I actually use it this evening.
Ok this is the recipe as I made it,
4c sm raw fir bark
2c sphag/peat moss
2c crushed coir
1c seedling mix
2c sm perilite
1c pumice
1c xsm granite chips
1c sm charcoal
1c sm red lava rock
1c sm black lava rock
1/2c oyster shell

Thats the recipe as it stands out, and these are all materials bought at my local stores without hydroponic or specialty stores being involved. Also without online store, does anyone in our community that lives close by know where to get large chunk sponge rock? Cannot find it even in hydro stores.

Your criticism is very important, without it, one cannot change anything Look forward to your reply, and will get a pic or 2 up
