I ordered a 100 gallon barrel and I'm still waiting for shipping confirmation but, I have 2 compost tea bags and each says they can do up to 20 gallons per bag so thatd be a total of 40 gallons. I also have an old package that I never used from maybe 5 years ago would it be worth throwing it in? I'm wondering can I add this stuff I got as samples to the bunch and help feed the microbes so that I wouldnt have to use 5 bags or should I use 5 bags? I have 2 of each sample. I have no compost of my own started but I do have some living soil concentrate from natureslivingsoil com.
