   • Also Known as Medium Coarse or Coarse. Ultra Tech's most popular grade. Ideal for mixes, growing vegetables, hydroponics, and small area gardening. Sometimes referred to as 'coarse.'

For Small Gardens and Hydroponics

Horticultural Vermiculite is a valuable growing medium for small area gardening and hydroponics. A mix of one part vermiculite, one part compost, and one part peat moss makes an ideal blend for small-area gardening, providing maximum growth.

A 50/50 mix of vermiculite and perlite is a popular medium for drip hydroponic and ebb-and-flow systems.

Mixed with natural soil, peat, organic compost, or bark, it will hold moisture, retain air, and provide plant food with a minimal amount of water required.
