How this works & sources
Wet soil before planting: FlowerDoo 201 and VeggieDoo 301 should be moistened well before use; saturate Seed Starter 101 before planting. Results are volume estimates of moistened, ready-to-plant soil based on the bag’s labeled volume (100% by default) plus a 10% settling cushion — both adjustable under More options. No manufacturer wet-yield factor is published.
1 cu yd = 27 cu ft. 1 cu ft = 28.316846592 liters = 7.48051948 US liquid gallons = 25.71404638 US dry quarts. Bags are rounded up after all pots of the same soil and bag size are added together; pots per bag round down.
