Description
Vermiculite, when combined with peat or compost, promotes faster root growth and gives quick anchorage to young roots. The mixture helps retain air, plant food and moisture, releasing them as the plant requires them.
Characteristics
- Increases water and fertilizer retention in soil
- Preserves bulbs and roots
- Germinating seeds and rooting cuttings
- Improves potting and transplanting
- Natural soil conditioner for lawns, gardens and plants
- Improves soil aeration
- Neutral PH
- Size ranges from Fine (0-2MM) to Large (5-10MM) but is mostly Medium (2-5MM)
Garden Clouds™
Garden Clouds™ is a ⭐ PRECISION-SCREENED ⭐ horticultural vermiculite available across Canada, designed to improve soil structure, aeration, and moisture retention for seed starting, propagation, and growing applications.
Looking to buy vermiculite in Canada? Garden Clouds™ offers consistent, high-quality, fully expanded vermiculite for gardeners, growers, and greenhouse professionals.
Vermiculite is widely used by growers because its lightweight, expanded mineral structure creates air pockets within soil mixes while retaining moisture and nutrients where plant roots can access them.
This balance between aeration and water retention makes vermiculite one of the most effective soil amendments for seed starting, cuttings, and potting mix formulation.
Why Vermiculite Quality Matters
Not all vermiculite performs the same.
Many general-purpose vermiculite products are packaged as broad blends containing varying particle sizes. These products are often intended to serve a wide range of basic soil-amendment uses.
Because of this, some products may contain partially expanded material, higher levels of dust (fines), or inconsistent particle distribution. These variations can reduce airflow, create compaction in soil mixes, and lead to less predictable growing conditions in sensitive applications such as seed starting and propagation.
Garden Clouds™ Premium products are engineered for reliable performance:
• Highly expanded vermiculite for maximum porosity
• Precision screened particle size for consistent structure and reliable performance
• Application-specific particle size fractions and blends
• Clean, low-dust mineral substrate
• Uniform performance in soil blends
This ensures consistent moisture retention and healthy root aeration across horticultural applications.
Common Uses
Garden Clouds™ vermiculite is commonly used for:
• Seed starting trays
• Rooting cuttings and propagation
• Potting mix formulation
• Soil aeration improvement
• Indoor and container gardening
Because vermiculite holds moisture while maintaining air pockets, it helps prevent soil compaction while supporting strong root development.
