Fort Light

Lightweight Compost-Based Potting Mix

Fort Light has all the benefits of a compost-based potting mix plus additional drainage from the addition of perlite. A complete germinating and transplant mix, Fort Light is ideal for growers using small-celled plastic flats or needing a lightweight mix. 

Fort Light is crafted from mature compost to provide balanced nutrition from germination to transplant. A favorite among flower growers, Fort Light can provide the ideal conditions to germinate and grow even the trickiest seeds. 

Fort Light or Fort Vee? While both are excellent choices for seed starting and potting up, most growers have a preference between the two. You may want to choose Fort Light if you are looking for a lighter-weight soil mix that will drain more quickly, especially in smaller-celled trays.

Ingredients: All ingredients used in Fort Light have been approved for certified organic production. Our composting process meets the National Organic Program (NOP) standard requirements and our products are approved by Vermont Organic Farmers (VOF), the certification branch of NOFA-VT.

The backbone of all our potting soils is the mature compost that we craft on site. To that foundation, we add high-quality, organic inputs selected to produce reliably outstanding soil.

Our soil recipes are iterative, as we frequently re-evaluate suppliers and ingredients against our goals of minimizing our environmental impact and producing a premium potting soil that growers can afford. For specific questions about product formulations, please contact us at

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.
