Just add 3/4 water products to produce a hassle-free seed-starting potting mix. These coir-based dehydrated and expanding soil discs also contain worm castings (plant food) and water-retaining crystals.
Once you add 3/4 cup of water (per disc) it will expand to perfectly fill one of our biodegradable coco coir pots.
We sell these items individually, i.e. 1 unit = 1 soil disc.
