Kindly go through the following points to understand how it's different:
1. Satopradhan cocopeat is already expanded, washed, and dried to escape you from the efforts of doing it all by yourself. If you bought a cocopeat block from somewhere, you would have to do all these steps yourself. So we have labor dedicated to this work.
A little bit of compost to make it more nutritious for your plants
Some vermiculite or perlite for better aeration
Neem Khali to avoid any fungus in it
You won't find this composition of cocopeat anywhere, and once you try growing in it you will be happy with the results too.
We have tried to keep the prices as low as possible. But all our gardening resources include the labor of our farmers, which when you buy rewards their efforts :)
