i posted about 2 weeks ago, about my rex begonia propogation attempt

http://forums.gardenweb.com/forums/load/begonia/msg0623252113624.html? 2

now, upon close examination, it seems there are little, almost too small to be seen. what looks like green mold. This is far too small to photograph, but picture 1/4 of a grain of rice, ontop of the soil
some cups have them ( 1 or 2 spots max) and a couple dont

but i can see there is root development on atleast 1

please note : i am using a soil mix w/ cocoanut fiber to retain moisture, for the propogation attempt

also, i have 1 leaf in a cup of water, that already has roots
and the whole leaf is still in great shape. (decided to try both techniques)

Thanks for any input

i used a pair of needle nosed pliers and removed the green spots, and the surrounding soil clump
also using a pair of scissors to trip any dead portions of leaves

during my inspection, i noticed most have root development

I believe this "mold" may have been from a bit of excess water, pooled in the corners of my tupperware base
if anyone has encountered the beginings of mold in a terrerium or propogation setup, please let me know the cause or if physically removing the affected areas
Also, i realize that mold spreads with spores, should i abandon this propogation attempt. or stick with it
(because i have the feeling i'll soon be seeing the " specs of red " as described in the propogation for newbies)

Thank you
Andrew
