A few years ago, my family purchased a coffee farm in kona. Not wanting to make any changes, the first year I learned the common locally practiced farming methods. At the same time I began to dig countless holes by hand to plant exotic fruit trees. The soil (if you that was what you called it) appeared much like other soils, but it was nothing more really than finely ground up volcanic rock.
A neighbor who was starting a farm wanted to manufacture organic fertilizers. I offered him my budget for chemical NPK if he would produce fertilizer for my farm as well. Shortly after, he spent time with Bob of G.E.O. and set up a compost tea machine. Two years later, after consistant applications of tea and some mulching, my ENTIRE 10-acre farm has transformed. Now, when I dig, I am working with a totally different, improved texture. Where it was just fine, ground up rock, now is black, rich dirt…when I rub moist soil between my fingers, it feels like silty mud–before it felt just like, well, tiny jagged rocks. Earthworms have even found their way to our land! On top of all that, I entered my coffee in the kona cupping contest this year and got honorable mention. The compost tea is helping me to grow some of the best coffee in the world, and that is official now!

“We regularly use a 250 gal. GeoTea brewer, as well as 2 GeoTea extractors, a 1000 gal. and a 50 gal., and are very happy with their performance. The simplicity of the designs, the quality of the construction, and the ease of use, of all these machines sets them apart from the other products on the market, and the end results are definitely of a superior quality.

“We have been using GEO Tea brewers, both a 250 gallon and 500 gallon model, in our Tea Center for several months now. The quality, construction and price make these machines top of the line systems. Easy to use, easy to clean and they make great tea too! We are very happy with these systems and even offer them for sale on our website. Good job, Bob! Keep up the good work, looking forward to the spray rig…”

“Excellent fungal activity!…Outstanding!…Good fungal community is present…Very good F [fungal] to B [bacteria] ratio…Good amount of the fungi present are active…Excellent ratio of activity for soil or foliar applications….”

“I am really impressed with the design on a lot of levels; it’s easy to clean, does a wonderful job of extraction on the compost, and my non-scientific “gut feeling” is that the wave-type action has an effect on the energy of the brew… I see ACT [aerated compost tea] as a mix of science and art, and your design seems to have made a leap of improvement that is hard to explain… We really wanted to get started (long story on why we hadn’t been brewing earlier, but the short version is simply that we hadn’t until July!), but I was almost positive that the brew would go anaerobic in the 100+ heat. We’re seeing beautiful diversity and actively-growing fungi - I just couldn’t be more pleased with it!”

I have used the GEO brewer several times for my clients and have had my brews tested by the Soil Food Web of New york and the results are great. I can see the difference in my client’s properties. The system is easy to use and creates qulaity compost tea.

Anyone interested on shareing there experiences involving compost tea and how to breed strands of fungal culture?
-what kind of substrate should we use
-would myceleum from wood chips work
right know we are using vermicompost-humus-fish emulsion-kelp, in a 12 gal growing solutions brewer-we see a bunch of OGM an nemetodes, a lot of living, but no strands of fugus. If anyone has any insight please let me know.
Thank you much
Rich
I have participated in both Paul Stamets cources. He covered the growing out of viable myceleum in a nutrient solution. this may be a source of info for you. I believe he is at fungiperfecti.com.
