Sinclair Vermiculite Medium 100L
The Sinclair Vermiculite Medium 100L is a naturally occurring, non-toxic mica mineral that has been heat-expanded to form a lightweight, sterile, laminated structure—perfect for use in soil conditioning, propagation, and seed germination.
With its unique ability to absorb and store nutrients, vermiculite prevents essential minerals from being washed away, instead releasing them gradually to developing plant roots. Its excellent water-holding capacity keeps soil consistently moist, while its medium particle size ensures balanced aeration and drainage, preventing compaction and root stress.
When used as a seed covering, vermiculite helps insulate against temperature fluctuations, improving germination rates and protecting delicate seedlings. Medium-grade vermiculite is also ideal for use with cuttings, potting mixes, and container gardening, offering a versatile solution for both home growers and professional horticulturalists.
Key Benefits:
-
100L bag of medium-grade vermiculite
-
Retains and releases nutrients gradually
-
Excellent moisture retention & soil aeration
-
Reduces compaction and supports strong root growth
-
Provides insulation for seed germination
-
Lightweight, sterile & easy to handle
