Coconut coir has many different uses. Not only is it a wonderful soil adjunct, it is a good hydroponic growth medium as well as a great bedding material for worm composters. And it has all the properties of a good propagation substrate for seedlings and plant cuttings.
Coir will not saturate with water; once it reaches it limit in retaining water all additional water water is drained off. To use it, soak it in water for 15 minutes.
Coconut coir is a sustainable, renewable resource that is free of bacterial and fungal spores, it lasts three times as long as peat moss and is a natural by-product of coconut harvesting. It is also readily available. Its advantages are:
- it replaces rockwool and other growing mediums,
- compressed bricks are easy to handle and store,
- it is disease resistant,
- has excellent air space and water holding capacity,
- it is of a neutral pH ande
- coir holds 7 times its weight in water.
When water is added to coir it expands; the 5 kg (11 pounds) brick sold below expands to 20 gallons in volume, the 650 gram (1.4 pounds) brick to 2.5 gallons in volume and the 250 gram (.5 pounds) brick to 1 gallon.
I highly recommend it for your hydroponics system.
