Description
Perlite is pretty much a must for creating the perfect free draining substrate. Use perlite by itself for hydro, or mixed with soil and other substrates to make a more free-draining, custom mix for your indoor and potted garden plants.
One bag measures about 35cm long x 16cm wide x 10cm deep, containing 5 litre of perlite. A nice easy size to store with your potting supplies, designed for indoor plant hobbyists who don’t need those massive bags you get at garden centres and hardware stores.
What is Perlite used for?
Popular used by itself for hydroponic gardening (soil-less gardening in water), or mixed with other substrates to create your own custom soil or soil-less mix.
Much safer than using straight potting mix for many of our indoor plant faves who are prone to root rot if stuck in dense potting mix. Adds aeration to dense, compact soil for a much healthier, more free-draining mix, reducing the risk of root rot from overwatering.
What is Perlite?
Perlite is lightweight. Used for soil-less potting mixes. Also used to improve aeration and texture in heavy, compacted soils. Perlite has no odour, is sterile, non-toxic, free of disease, insects and seeds. It won’t break down, rot or decompose. Popular for seed germination and propagation, hydroponics and container gardening. A common ingredient in custom soil mixes adjusted to suit the plant being potted up.
Why mix perlite with other substrates?
Perlite by itself doesn’t hold much water – about 1% on average – so is best used with other more moisture-retaining substrates.
