Discs are compressed coir pith made, especially for use in pots. Different sizes of discs are available to suit various pot sizes. Discs are also made with a hole in the middle to facilitate easy planting. Fertilized discs are made as per customer requirements. Disks are made from the coarser particles of coir (>1mm) which gives much better substrate for plant growth.
The nursery seedlings grown on this disc medium can be easily uprooted and transplanted without damaging the root zone i.e. transplantation shock is minimized or avoided.
