Perlite, Vermiculite and Hydroleca are all very similar products and as such many people get confused about when they should be used.
Perlite – retains some water but also provides drainage, ideal for plants that need to dry out before being watered, can be used when re-potting seedlings and rooting cuttings, will loosen clay soil in the garden
Vermiculite – retains water so is ideal for plants that need to be kept moist at all times, excellent for developing strong healthy seedlings but care should be taken not to overwater
Hydroleca – formed of small baked clay balls which absorb water, commonly used in hydroponics they can be used to ensure that plants are not overwatered, placed in or under a pot they ensure that the plant roots are not sitting in water
