Per-container amendments

Scaled linearly to your container size. Apply at transplant or as side-dress per the notes on each line.

Growing notes

- Keep the separate 10% vermicompost — the blend's 10% addition only includes a fraction as worm castings. - No pre-charging needed; the blend is ready to use. - Shopping math: 3 batches each of pepper + tomato (6 batches ~67 gal mix) needs ~27 qt of blend = ~0.9 cu ft.
