  • Excellent for mushroom production
Style: Mushroom Cultivation
Very impressed. Excellent quality and much easier to break up and work with than standard coco coir. Seems more fluffy & aerated, and hardly any of those long irritating fibers that are normally all over. My crew loves this.

Style: Indoor Plants
Using Mycelium Coco Coir has truly transformed the way I care for my indoor and outdoor plants.

The packaging and product were both impeccable, earning a perfect 10/10 rating from me. I am thrilled with my experience and will definitely be a loyal customer going forward. ... show more

  • Works great! Add fertilizer. Works great! Add fertilizer.
Style: Indoor Plants
1 block overfills a 64 quart container! This is just a supplement to your soil, not actually soil. Meant to replace peat moss, is a sustainable product peat moss is not sustainable. Works great for starting seeds fertilizer is not necessary for seedlings but if you use for gardening you will need to add some other components like perlite, or vermiculite as well you will need to add something containing fertilizer, like potting soil or Osmocote fertilizer as coco coir contains no nutrients. I mix mine with topsoil, perlite, Osmocote/composted manure. I don't worry about salt content as I use to plant carrots and golden berries that are naturally salt resistant. ... show more
