Besgrow Orchiata is a standalone orchid growing substrate that can be used directly from the bag. Produced from 100% pure New Zealand Pinus radiata bark, it is a unique, stable substrate for potting and re-potting orchids.

Orchiata is a sustainable orchid growing substrate produced from the finest quality, 100% pure New Zealand Pinus radiata bark. Pinus radiata is sourced from renewable, man made forests ensuring availability into the future.

New Zealand Pinus radiata is a hard and stable bark compared to other pine species; however, it needs to be processed from its raw state. Our unique natural process creates a high quality, stable, long lasting, toxin free, consistent growing substrate available in different sizes for your specific growing needs.

Our process allows Orchiata to hold water and nutrients on the outside layer of each chip, as well as creating a slightly rough surface for roots to anchor to. Pathogens do not survive this process, however beneficial micro-organisms remain.
