DIY Seed Starting Mix
Those ingredients are perfect for a DIY seed starting mix, and they serve as both a growing medium and a mild fertilizer. Here's a breakdown of what you're looking at:
🧪 Ingredients:
1. Coco Coir
-
What it does: Lightweight, holds water well, and provides good aeration.
-
Replaces: Peat moss (eco-friendlier).
-
Nutrients? Minimal — mostly structure and moisture retention.
2. Vermiculite
-
What it does: Improves moisture retention and aeration.
-
Nutrients? Contains trace minerals, but not a major nutrient source.
-
Common in: Most seed starting mixes — it helps seeds stay moist and oxygenated.
3. VermisTerra Worm Castings
-
What it does: Provides a mild, balanced organic fertilizer rich in microbes.
-
NPK (approx.): ~1-0-0 to 1-0-1, gentle enough for seedlings.
-
Bonus: Adds beneficial bacteria and fungi that promote strong roots.
🌱 DIY Seed Starting Mix
Mix Ratio Example:
-
2 parts Coco Coir or Peat Moss
-
1 part vermiculite
-
1 part worm castings
You can adjust based on what you need:
-
More vermiculite if your area is hot and dry.
-
More coco coir if your mix seems too wet or heavy.
✅ Why This Works Well for Seedlings:
-
Light and fluffy — seeds sprout easily.
-
Moisture-retaining but not soggy.
-
Worm castings feed seedlings gently, so you don’t need extra fertilizer right away.
Optional Additions (If You Want to Boost It Later):
-
A dash of kelp meal (for micronutrients)
-
A sprinkle of mycorrhizal inoculant (for root health)
-
Compost tea or diluted fish emulsion after seedlings grow true leaves
