🪴 Seedling Starting Mix

Premium Organic Blend for Strong Germination & Healthy Roots

Our Seedling Starting Mix is specially crafted for plug and cell trays, creating the ideal environment for germination and early plant development. It delivers the perfect balance of moisture retention, aeration, and microbial activity to support strong, healthy seedlings from the very start.


🌿 Key Features

  • Fine Texture for Germination
    Provides excellent seed-to-soil contact, ensuring seeds stay moist and anchored—encouraging fast, even sprouting.

  • Moisture Retention & Drainage Balance 💧
    Holds water effectively without waterlogging, reducing the risk of damping-off.

  • Aeration for Root Health 🌬️
    Light and fluffy structure supports airflow to roots, helping prevent compaction and root rot.

  • Boosted with Microbial Life 🪱
    Worm castings introduce beneficial microbes and gentle nutrients for a strong, resilient start.



☀️Ingredients

All ingredients are approved for use in Canadian-certified organic crop production.

  • Canadian Sphagnum Peat Moss

  • Coconut Coir Fibre
    Improves water-holding capacity and texture

  • Small Perlite
    Keeps the mix light and fluffy while enhancing drainage and root aeration

  • Worm Castings
    Natural source of nutrients and beneficial soil biology

  • Dolomite & Limestone
    Buffers pH levels while providing essential calcium and magnesium for strong seedling development

 

🌵  HOW TO USE

Pre-moisten the mix until evenly damp—never soggy.

Fill plug or cell trays loosely, leaving a small space at the top.

Sow seeds at the depth recommended on your seed packet.

Mist gently to settle seeds and keep the top layer evenly moist.

Use a humidity dome to retain moisture during germination. Choose a dome height that allows room for seedlings as they grow.

Provide consistent warmth and light—seedling heat mats and LED grow lights are ideal for strong, even growth.

After germination, maintain steady moisture and airflow. Use a small fan to strengthen stems and prepare seedlings for life outdoors.

Position LED grow lights 4–6 inches above seedlings to prevent stretching and promote compact, healthy growth.

Once seedlings are ready, transplant into our Living Organic Soil Mix to give them a microbe-rich base and continue feeding with compost tea and liquid amendments as needed.
