First post doesn't give a link and I'm too lazy for
html or I forgot :-)

It's the second one.

Here is a link that might be useful: Mighty Myco Soluble Premium Mycorrhizal Inoculant

Mycorrhiza is a relationship that fungi have with plants. "symbiotic relationship between fungus and plant: a mutually beneficial association of a fungus and the roots of a plant such as a conifer or an orchid, in which the plant's mineral absorption is enhanced and the fungus obtains nutrients" as found in Encarta's Dictionary. Mycorrhiza are not a type of fungi. Make your soil a good, healthy soil and the fungi in that soil will develop that mycorrhizal relationship.

kimmsr, so what you're saying is don't waste it in the tea, but use it in the potting mix? I've already got it. The smell is quite strong, I put it in the pantry where the seedlings would be going and had to move it to the garage. The odor is still in the pantry this morning. Smells reminds me of a very strong multi vitamin pack.

The people that are selling Mycorrhizal Fungi products are selling "magic elixars", not anything of any real substance. The way to get that relationship established on your plants is to make a good, healthy soil and it will happen with out spending money on these "magic elixars".
