My Experience with Holganix
I went to the seminar in 2011 and listened to the presentation. Overall I would say I have an above average knowledge in soil science. I was not real impressed on their unique selling position of save the world with our product, and by the way you can add pre-m,merit,talstar,3way, etc.
I did get a quart sample to try out at my home for my landscaping plants. This was enough to treat my beds about 3 times at 6-oz/1000. My plants are well maintained and was difficult to see a big improvement. However, I do feel that all the good mychorrhizae and bacterias did help suppress disease.
For the cost and the fact it needs to sit shotgun next to my beer in fridge, I never ordered.
I had good success in 2012 with, Bills ICT product on some postage stamp lawns in one developement. Liked his product it was a compact kit and could just sit on my shelf in shop. I used the ICT in a hybrid granular/liquid program and did very well considering the drought. Also my cost per k was half of Holganix
