Out of scientific curiosity, I obtained some biological growth stimulant products
to see if they do indeed provide a growth response. I obtained 3 products from JH
Biotech, Inc(www.jhbiotech.com);

 1. Promot MZM, an organic starter fertilizer but which also contained fermentation
    by-products of a fungal fermentation process;
 2. Superzyme, a biological growth factor with various bacteria and fungi and;
 3. Mycormax, a mixture of several mycorrhizae.

Previous research has shown that the addition of mycorrhizae fungi can result in
a growth response on potatoes in Kern County, especially if the field has be previously
fumigated. I had very little experience with other growth stimulants but have seen
them work in past experiments.
