So I found this soil or is it compost ? It cost $75.00 a cubic yard. The mixture is 33% premium composted aspen / 33% chicken manure / 17% black lava fines (sand) / 9% expanded shale / 8 % pumice. I'm going to try the global bucket this year and some 21gallon DIY earthboxes. Going to have 40+ 5gal buckets to fill plus the 4 21gal containers. Trying to budget if at all possible. Any thoughts? Thanks
