Blended from mature compost; sphagnum peat moss; coconut coir; perlite; gypsum; blood meal; feather meal; kelp meal; bone meal; vermiculite.


  • Seed germination
  • Transplanting vegetable and flower starts
  • Transplanting houseplants
  • Hanging baskets

Best Practices

Prep For Use

Wet product with warm water a few hours prior to planting or soil blocking. This allows the soil to stabilize and prevents soil from washing out of pots or trays.


Avoid drastic changes in moisture/saturation. Store under cover, out of direct sunlight. Protect from weed seed, petroleum products, and other contaminants.

Supplemental Fertility

Usually, no additional fertility is required. If roots have filled the container and fertility is needed, top-dress with Compost Plus and water-in.

Storage and Shelf Life

Store in a neutral environment which encourages moisture retention and protects from UV light. For optimal performance of living soil we suggest using it within 6-9 months from date of purchase, although it may perform adequately for up to 12 months. For more detailed information, please refer to our article on storage and handling.

"Fort Light has been a mainstay on my farm for the last 10 seasons. For healthy seedling production there is nothing better, more consistent, or dependable on the market."
