Ahhh, buying local is nice (part of that sustainable thing)...40lb bag of Agrowinn EWC (not compost) set me back a whopping $30 at OC Farm. Some say Agrowinnn (sourced from San Diego area) is too dry (about the consistency of used coffee grounds) but since it is packaged by weight (not volume)...I say it's all good. No reason to pay for moisture if it is not needed.
Proper moisture content keeps the microbes active and happy.
