Pot Size, Soil Volume & Drainage
The specification desk of the site: numbers, not vibes. Root-depth requirements per crop, litres and cubic feet of mix needed for common pot dimensions, why a 12-inch pot fails a tomato, how drainage holes and the physics of the perched water table actually work, and why the gravel-in-the-bottom trick backfires. Every piece aims to end with a figure the reader can act on in a shop aisle — comparison tables, quick-reference charts and simple volume maths readers can redo for their own pots.
