Cultivation Practices​

At Grumpy’s Organic Farm we create an environment that closely mimics nature’s optimal conditions to consistently produce clean medical cannabis products with every harvest cycle.

To Provide The Highest Quality
Organic Products and Services.

Our methods emphasize probiotics; fruit and plant ferments are crafted on site, as well as sprouted seed, herb, and compost teas. We amend with biologically active top dress customized to both soil test results and strain preferences. We only provide our ecosystem with essential micronutrients found in nature; we choose our amendments with care to maintain consistent levels of bioavailability.

By excluding factory farm animal by-products commonly used in organic agriculture as a cheap source of fertility, our harvests are higher quality, ethical, and sustainable, with more fragrant bouquets and abundant terpene profiles. We never need to worry about nutrient overload that can be created by these by-products, which negatively impact both the burn quality and full aromatic experience of the flower.


Rather, we mostly use plants to feed our plants, as they already have a near perfect balance of nutrients, as well as terpenes and other beneficial compounds that commercial amendments lack. And because everything that goes into our soil is food-grade, we do not need to “flush” anything out! Driven by our passion for health and providing the safest product possible to share, we feed our plants as we feed ourselves.


The Freshest.

Grumpy’s Organic Farm is one of the few grow facilities in Maine to receive MOFGA’s Clean Cannabis Certification. This third party certification relies on USDA organic standards and applies them to cannabis cultivation using sustainable, natural and organically based practices. The Clean Cannabis Program, established in 2018 in Maine, emphasizes compliance, inspection of seed-to-harvest practices and testing for pesticides and contaminants. The annual certification validates Grumpy’s commitment to cultivating clean cannabis. Grumpy’s continues to be a leader in organic best practice since opening in 2015.

Environmentally Sustainable:

As little waste as possible, low-impact, on-site compost of byproducts, harvesting free condensation water, geothermal, climate controlled greenhouses, closed loop system.

Beyond Organic:

No chemicals or synthetics, sun-grown, no store bought bottled or man made synthetic ingredients allowed on our farm!

Living Soil:

Essential nutrients, compost tea, plant-based amendments, connection to the earth, ideal root environment, soil biology.

Vegan &
Cruelty free:

As part of our mission to create sustainable cannabis. We only use products that are free from animal testing and contain no animal products.

Living Soil

Living Soil is a growing method centered on the microbial life inside the soil. Through evolution over thousands of years, Mother Nature has developed a symbiotic relationship between the plants and the microbial life in the soil: fungi, bacteria, protozoa, and many other types. These microorganisms form a soil food web that help feed the plants, in exchange from carbons and sugars that the plant releases (extrudes) through their roots into the soil.

Environmentally Sustainable

Environmental sustainability is the responsibility to conserve natural resources and protect global ecosystems to support health and wellbeing, now and in the future. Because so many decisions that impact the environment are not felt immediately, a key element of environmental sustainability is its forward-looking nature. In fact, the U.S. Environmental Protection Agency defines it as “meeting today’s needs without compromising the ability of future generations to meet their needs.”

Beyond Organic

Modern organic farming was developed as a response to the environmental harm caused by the use of chemical pesticides and synthetic fertilizers in conventional agriculture, and it has numerous ecological benefits. Compared with conventional agriculture, organic farming uses fewer pesticides, reduces soil erosion, decreases nitrate leaching into groundwater and surface water, and recycles animal wastes back into the farm.

Vegan & Cruelty Free

Our goal at Grumpy’s Organic Farm is to produce the tastiest clean-burning cannabis in a low-impact and non-harmful way: we continually work to reduce our environmental footprint and ensure that our grow methods produce as little waste as possible. We strive to grow flowers that are healthy for you to consume; no store-bought bottled or synthetic ingredients are allowed on our farm. We craft our own compost teas and ferments produced from sustainable sources, largely food and herbs grown on our certified organic farm.

Grown With Love on Our Farms

We provide a safer, cleaner alternative to commercially grown cannabis. Our plants are always grown in organic living soil without the use of pesticides, artificial nutrients or fertilizers. While hydroponic and fertigation growing might be easier and faster, we know that the extra effort we put into growing our plants is worth the wait.
