Seedling Soil Mix Calculator
🌱 Seedling Mix Calculator (5:3:2)
This uses your exact mix: 5 parts base (peat/coco) : 3 parts perlite : 2 parts worm castings.
Peat gets lime. Coco doesn’t.
Peat gets lime. Coco doesn’t.
Examples: 1, 3, 5, 7, 10
How many you’re filling
“Pulverized lime” = usually dolomitic lime powder.
Example: 1.2 gal becomes 4.8 quarts + “about ¼ of a 5-gal bucket”
Enter your container info and hit Calculate.
Lime math: your recipe is ½ cup per 10 gallons of total mix → that’s 0.05 cups per gallon (peat only).
