Steelheader,
Actually I add mycorrhizal mycelium fungi to all my plants roots on transplant from clone (solo cup) to their air pot.
My understanding of the symbiotic relationship between my plants and mycorrhizal is that the fungi attach themselves to the plants roots and extend the ability to uptake nutrients. So seeing a mycelium loop a neamotode is cool by me for that fungi will take the N in that little worm and send it right up to the plant roots it is attached to. So instead of waiting on that worm to digest the organic N in the soil to make it available it seems to me my fungi friends speed up the process by tying up these free wheeling nematodes and squeezing the shit of them to get the N quicker to my plants roots.
I think what happened to me is simply I put too much carbon (molasses) when feeding my microbeast, essentially I expotentially grew more beast then there was N in the soil to keep everyone happy including my plants.
Again I am happy to report all is well now and I did not have to take any major course of action expect not to feed with molasses for awhile till I get a good supply of organic N back into the soil then I will attempt to grow my microbeast again!
Speaking of educational mushroom video this is one is great..
