Gro-Sure Vermiculite is a naturally occurring mineral which has been heated to high temperatures to produce lightweight, absorbent flakes, perfect for a range of gardening tasks. It encourages strong, healthy seedling growth and establishment. The fine grade flakes can be used on their own or added to Gro-Sure Seed & Cutting Compost to:
Help compost hold onto vital plant nutrients
Increase compost water retaining capacity
Insulate seeds against damaging temperatures and humidity changes (when used as a seed covering)
Vermiculite is a naturally forming mineral that is extracted from mines. The natural laminar structure allows the material to expand up to 30 times its own size during heating. Its natural shape once heated gives excellent insulation, drainage and aeration properties
Gro-Sure Vermiculite is ideal for growing from seed and to help both indoor and outdoor plants. Vermiculite helps to absorb nutrients, preventing them from being washed out as well as releases them as required to plant roots. Vermiculite is a naturally occurring, non-toxic material heated to a high temperature to produce a lightweight material with a high surface area.
