I am an old veggie and herb grower and have done a lot of growing in pots. I wish I had found coco years ago, but just learned about it with this new crop. It has all the good qualities of spagnum without the bad; light and airy while being easy to wet. Let sagnum dry and it is probably easier to get dried concrete wet. Water will run through coco fast, so I have my auto drip set to a slow flow so it has time to spread rather than run through. I like to water to just a little runnout, 3x per day, then give them a good flush once a week. But that will likely change a few times as I learn.
It is a bit acidic, so that needs to be considered for a few weeks. After that the pH has stayed the same coming out as going in. Also, I had one plant showing signs of calcium deficiency, which I learned is common with coco. A cal/ mag supplement took care of that in no time.
There are some really good threads in 420 that go into a lot of detail. For me, it's all pro-pro so far. I will be adding it to my veggie pots this spring.
