Coco coir: superior to peat moss, this is a sustainable base for your soil. It holds lots of water and has a fine texture.

Coco chips: add this to break up the texture of your soil, improve drainage, and give roots something to grip onto. Adds air pockets and absorbs a small amount of water.

Rice hulls: improves drainage and aeration of soils by creating little air bubbles throughout the soil. Breaks down into a rich compost.

Pinus radiata bark fines: small bark chips that are perfect for rooting blends and small epiphytes. Add these to your soil mix to improve drainage and texture.

Pinus radiata bark chips: medium bark chips that are great for larger epiphytes. Greatly improves drainage in any soil mix.
