Jolly Roger

Flowering & Fruiting Container Mix

Jolly Roger is specifically crafted for container cultivation of plants with high nutrient needs, including cannabis, tomatoes, and hemp. A compost-based mix, Jolly Roger combines the benefits of a living soil with the plant-available nutrients and minerals that a heavy-feeding cultivar requires. 

Transplant into Jolly Roger once plants are fully established. To extend vegetative time and produce the highest yield per plant, choose a container as large as the plant you hope to grow.  Jolly Roger also excels in “sea of green” grows with smaller containers and shorter vegetative periods. Jolly Roger is not intended for seeding or cloning.  Consider Fort Vee or Fort Light for these applications.

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

The backbone of all our 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 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


  • Transplanting/finishing cannabis, hemp, vegetable, and flower-starts. 
  • Repotting established heavy feeding houseplants.

*Note: Jolly Roger is not recommended for cloning or germination.

Best Practices

Prep For Use

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


Avoid drastic changes in moisture/saturation. Store undercover, 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.

"I've been super  impressed with Jolly Roger for our greenhouse cannabis crops. I wanted to get an idea of the baseline for one flowering cycle with no additional fertilizing, so I didn't feed any nutrients or amendments besides a light fish emulsion fertigation at transplant. The yields are great, the flower looks amazing, and the plants are very happy!"
