    I was wondering if anybody out there has experienced or observed that when commercial mycorrhizal products consisting of common endo ecto blends on powdered carriers are put into solution that a majority of these spores will float to the surface and the carrier will sink once agitated and left to settle?

    These are some picture's I took , you can see the large circular spores floating that i believe to be some of the glomus family species possibly?, I noticed none at lower depths in solution except smaller "possible" spores of unknown type.

    In some of the pictures it may look like there are large clear spores too, but it is the way the light is refracting of smaller deeper materials that is causing that effect as I recall.

    Any feed back would be much appreciated.

    yes they float they are dry to start= more air than water. most of the time we use a myco powder we let them set in water over the days before we use them 24 hours or so. also what is the water got in it to start with??? more dense water = better float like dead sea water..........

    they use sugar water for a gradient i think, more dense, you where right the first time.
    thanks for the tip about soaking

    cool pictures how did you do that? Is that a microscope?

    Most dry inoculums have a clay base, the clay will sink to the bottom for sure

    I think that is a safe bet (given moisture is a germination requirement), but I can dig through my archive if you want.

    it also would appear to me that that is a cotton seed meal base. is that myco from terranova or O labs??
