He sells it cheapest directly from here and an eBay account from what I've seen. It's 1 tbsp each per gallon of Root and Foliar and there is a large thread on here you can check out. You'll use a lot more of them than the nute pack (mycorrhizae).
MY tea:
4 gallons of RO water
10 ml Grow More Armor Kote (Potassium Silicate)
60 ml Full Power (Humic Acid)
20 ml Grow More Seaweed Extract (Kelp)
10 ml Grow More Jump Start (Super Thrive)
100 ml Mendocino Honey (Molasses)
5 ml Organic Gem (fish hydrolyzate) combats foam.
PH here if needed
4 tbsp OG Biowar Foliar pack
4 tbsp OG Biowar Root Pack
Brew 4-20 hours
Add:
4 ml
Sea Green
Brew 30 mins and water in.
I shoot for a PH of 6.1 before adding the
Sea Green as it'll push it to 6.0 normally.
Foliar:
1/2 gallon Tea
1/2 gallon RO water
5 ml Grow More EZ Wet SE (Surfactant Highly Recommended)
10 ml Mendocino Fuego (Amino's)
5ml Grow More Bio-Cozyme
1 gallon sprays my whole garden since my sprayer is so efficient. I like the Mendocino Honey when I'm going to foliar as it has some
yucca in it as a natural surfactant and is much thinner than the Mother Earth Sugar Load high brix molasses I have also used.
