Vermiculite Coarse Grade - 20 Qt Bag

Looser Mixes That Hold Water for Roots - 20 Qt Bag

Compacted media starves roots of air, and dry-out between waterings stresses plants. Coarse grade horticultural vermiculite keeps a mix open so roots can develop, while holding moisture and nutrients for later use. It is described as clean, odorless, non-toxic and sterile, so you start from a clean medium.

The 20 Qt bag suits home gardeners, small-area growers and anyone trialling vermiculite in a soil blend or hydroponic medium before moving to larger volumes. Commercial operations can buy by the bag for blending and top-ups.

Key Features & Benefits

• Coarse grade — keeps mixes open and reduces clumping around roots.
• Moisture and nutrient retention — holds water and feed for later use by the plant.
• Sterile, odorless material — gives you a clean starting medium for cultivation.
• Garden and hydroponic use — blends with soil, peat, compost, bark or perlite.

Who Should Use Vermiculite Coarse Grade Bag

Choose it if you mix your own growing media, run small-area gardens, or use drip or ebb-and-flow hydroponic systems and want better moisture retention and aeration.
