The only thing i would do diffrent in that tek, that i havent updated yet. is to use "Wild Bird Seed" (which u can find cheap at $10 for a 20Lb bag)

then mix it at a 2:1:1 ratio of Verm:WBS four:Water
you can find a 23 quart pressure cooker (holy shit it dropped in price!) for $59 on amazon.com

The second best investment (but not necessary) is this dehydrator.
