The beauty of AACT is that you don't need any 'products' other than:
1. dry inputs containing beneficial organisms (EWC is great for bacteria, woody stuff and anything really has fungi ie compost, peat moss, old soil, basically everything is covered in microbes)
2. A food source for the different types of microbes (B/A prefer carbs and molasses is most common although any carb will do, fungi like proteins and replicate slower so you can give them a head start in a 'santas beard' with oats or other food sources, fungi do not replicate in the AACT they only grow longer hyphae)
3. A secondary food source containing micros and trace elements. Liquid kelp is the most popular. I also use Glacial Rock Dust, soft rock P, $$$Earth Tonic$$$, ocean salt or himalayan salt. This is critical for enzyme production every enzyme is built upon a micro/trace ion, if these are not available in the tea the microbes will make due with whatever they can build with what they have been presented.
Last. Highly oxygenated pure water (at least no antimicrobial chlorine/chloramines). Brew a minimum of 24 hours IMO. Tim at microbeorganics.com likes 36-48 hours for maximum diversity.
** The above are required to make AACT to boom the bennies. Another use of AACT is to create something with bennies and a bit of NPK for what phase your plant is in. This is where Alfalfa Meal, Kelp Meal, Guanos, and other common soil amendments come into play. Check out Vital Earth's tea chart for a general guide to making a nute and bennies AACT.
And to keep it uber simple good teas can be brewed with nothing more than compost, carbs, and pure water. I like to let mine brew 36 hours to get a nice diverse community going in there. I usually dilute my AACT now at least 1:2 up to 1:5.
If you want to add mycos into your tea (a powdered product) then do it right before you water it in or else the other microbes will just feast on your dormant mycos before it has any chance to colonize the root and you will just be wasting your money. Matts veganics thread also has lots of tips concerning using bottles and teas together to get the most bang for your brew and buck.
