Coarse Grade Perlite, 3-6mm particle size. A naturally occurring non-toxic, natural volcanic rock which is heated to a high temperature to produce a lightweight micro-porous medium. Perlite is an ideal additive to terrestrial orchid composts as it improves aeration and drainage while retaining moisture. Helps to prevent compaction. Also good for adding drainage to Dactylorhiza and epipactis composts. Some Cypripedium growers use only coarse perlite with 10% organic matter added as a growing medium. Price is for one 3 litre resealable bag of coarse grade perlite 3-6mm particle size. |
