I love growing in coco, but it is a little bit of a commitment without watering system. Coco also has a few things that are kinda specific to growing in it, so please do your research first if that’s what you decide on.
I’m not a huge fan of fox farms, but I also don’t believe that nobody by you sells it. The stuff is literally everywhere! They have a retail locator on their website, try it and see. If all else fails, roots organic seems like pretty good product.
