Quality Flower Starts With Healthy Plants

At Heirloom, we strive to be as organic as possible and comply strictly with all MA DPH/CCC Regulations. It is our goal to go above and beyond; collaborating with these agencies to further improve understanding and safety.

We take an approach we call “Gently Grown” which applies from seed to sale. Quality, organic fertilizers and ultra-clean water ensure that our plants are thriving from day one.

With the use of sophisticated, automated climate-control systems; our Cultivation Team is able to focus the majority of their time on each plant’s individual needs. We have a sharp focus on creating optimal microbial environments to promote root health and plant growth. By maintaining a healthy root environment and specific climate conditions; we are able to avoid the use of pesticides and foliar.

Throughout the cultivation and harvest processes, we ensure that each strain gets the specific attention it deserves from our feeding program. This protocol allows us to optimize each strain’s beneficial attributes (cannabinoid-content, terpene-potency).

Each of our unique strains and their growth progress is documented during the process. This allows us to keep track internally of the best methods and have them backed by real results in the product.

Landrace cannabis seeds

Pure cannabis strains (also called landraces or purebreds) have developed in its natural environment and has never been crossed with any other strain but inbred through many, many generations. These varieties are very stable and present very few variations – if any from one plant to another.

Most landrace genetics are then 100% Sativa or 100% Indica, although there are some exceptions. Normally, pure or landrace cannabis strains often include their country or region of origin in their name. Examples: Hindu Kush (Indica), Acapulco Gold (Sativa), Panama 74 (Sativa), etc.

Pure strains have the advantage of offering very original flavors and effects, pretty different of those from today’s hybrids, which often contain the same genetic basis (Skunk, Haze, etc.).

These pure strains will bring amazing memories to smokers from the 60s/70s, since at that time this was the type of marijuana normally available on the market.

About Us

Organic Heirloom Cannabis Genetics

Swami Organic Seed is the embodiment of “pura vida” in organically produced cannabis seed. Utilizing the Living Organic Soil methodology we helped establish in cannabis gardening along with Brotherhood of Eternal Love genetics we were gifted by a former BOEL member/associate, we breed for various outcomes in cannabis.

Preservation of Heirloom Cannabis Genetics

Preservation and future development of these heirloom and BOEL genetics are among the priorities we take as a responsibility to cannabis. I personally remember what it was like to enjoy cannabis of the 70’s, and as cannabis activists we are dedicated to bringing these forgotten human pleasures to the modern age. We bring lifetimes worth of cannabis history, cannabis gardening, and cannabis genetics together in Swami Organic Seed.

Why Do We Do This?

Because multiple combinations of poorly selected breedings over the last few decades have produced disease prone types that often lack the desired effects in both indica and sativa preferences. The stronger indicas that were ever present twenty years ago are all but extinct today. Sativa types have been selected to near monotony as well. Overall, the more important genetic aspects of cannabis are often overlooked and bred out. We’re on a mission to change this and make available to future generations that which is truly great cannabis.
