Welcome Naeem,
Those are impressive results.
Before I read your post I just ordered some Coco Coir....I am so glad you went the smart route.
I am using perlite and composted cow manure, and I wanted something better..we also have fungus gnat issues because of some potting soil we are growing hot peppers and herbs in...
I have no idea what took me so long, but your post is proof that coir is the best way forward.
