Bcuzz works best for me, hands down... That's why I use it. And it's available locally.
Is the b-cuzz coco pre charged?
Interesting. My only concern with the precharged coco is burning seedlings and clones. I bought a bag a couple years ago and when I went to rinse it, it had 750ppm coming out. which is too high of an EC in my opinion. Never knew they did that on purpose. Canna all the way.
I would even drive up to a couple hours away for b'cuzz if it wasn't available locally. awesome stuff that's worth the added hypothetical inconvenience and price
