5) Now soak the CHCs in plain tap water.
6) The chips will float on the surface owing to a lot of air spaces in the husk as well as the density. You will need to weigh down the chips using some bricks.
There are a lot of soluble substances in the husk, you can already see that the water in the bucket has turned reddish brown. There is a debate as to whether these substances are harmful or beneficial for roots. Some say that the tannins are antifungal antibacterial and have plant growth hormones that stimulate rooting, others saw that they inhibit root growth.
One point I would like to mention here is that, I do not live on the sea coast, nor are my coconut husks soaked in seawater to soften them (which is the industrial way of doing it) therefore there is no salt present in my coconut husk.
I usually soak the chips for a day in this water, and then I change the water and add a fungicide to it, I let them the soak overnight then dewater them and spread them to dry. I then store them in plastic or jute bags till I need them.
Tomorrow I will post a thread on how I use this media to pot my orchids. I hope this helps enthusiasts who want to try their hand at this media right from the scratch.
