Perlite adds aeration and drainage, reducing the risk of root rot. Popular used by itself for hydroponics and semi-hydro or mixed with other substrates to create your own custom blend. A superb propagation substrate (just add fertiliser). Also popular mixed 50/50 with Stratum (aqua-soil), for alocasia corms and hard-to-root cuttings.
Available in two grades from Bio Leaf: Coarse (this grade) or Chunky / Super Coarse (get that size here). I also have Egmont Perlite available which is the standard fine to medium perlite size.
Bag size and perlite size
Bio Leaf Coarse Perlite is a little larger than the standard size (if you're wanting a standard size go for the Egmont Perlite instead). This is more of a medium to coarse size, around 4mm to 1cm long by about 2mm to 4mm thick on average. Being a natural product you'll get a variety of sizes in the bag.
The bag holds 2 litres. That's a bag roughly 18cm across x 25cms tall and about 5cm wide but that can't be exact because litres is measured by volume not weight, so just a guide to help you visualise how big the bag is. 2 litres of perlite would fill around an empty 15cm to 17cm wide pot if filled only with perlite (in real life it'll usually fill more of course as the plant roots take up a fair bit of room in a pot, plus you don't fill pots with substrate right to the rim).
How much water does perlite hold?
How big the perlite is changes how much water it holds and how well it drains:
Used by itself, an EXTRA-FINE perlite drains slower and increase water hold capacity to about 60%+
FINE perlite has normal slow'ish drainage and around a 40%+ water holding capacity.
MEDIUM perlite offer faster drainage and lower water holding, around 30%+
COARSE or CHUNKY is very fast to drain and has the lowest water holding capacity, around 20%+
Egmont Perlite is around fine to medium in size, which would be considered the standard size of perlite. Bio Leaf Coarse Perlite (this grade), is around medium to coarse. Bio Leaf Super Chunky Perlite is up at the coarse to chunky range (super chunky perlite available here).
