perlite
 

repotted some of my cyms in a bark/perlite mix,the perlite is a fine grade.its my first time using perlite it seems odd to me,it never seems wet like its holding water.

You're right, perlite doesn't hold much moisture but it provides aeration to the mix. I've always used the large perlite which is also called sponge rock, but I don't grow cyms so I don't know what's appropriate for them.

Cyms like #3 or #4 Sponge Rok. Definitely larger than the small or agricultural grade mentioned here. The smaller one is fine with seedlings as a combined mix with fine bark.

so what should i do now,i have one more cym to transplant?should i use a finer grade of bark or add some sphagum moss to the mix?

I would not worry about it. Cyms don't seem to be very fussy. I have used smaller perlite without issue. It may not help anything, but it hasn't seemed to hurt at all.
I usually use a combination of fine and medium bark, and toss some styro pnuts in (just not the green ones!)

Sonya, Why not the green ones??

Some styro peanuts are env. friendly. They are made from cornstarch and dissolve when watered.

The dyes used in some styrofoam peanuts is phytotoxic.

The peanuts made from cornstarch are NOT styrofoam, but still should never be used in a flower pot, as they dissolve in water and form a gummy, root-suffocating mess.

Green ones are meant for electronics, and have some anti-static treatment.

Actually pink ones are the super-static-eliminators. Green and blue dyes are used to indicate they are recycled, rather than new, and the green is a slightly-antistatic coating to aid in dry-climate packing, more than for electronics.
