Madcow Strain

Madcow is one of the most interesting Sativa-leaning strains to come out in the market. Though mentally stimulating and energizing like a typical wake-and-bake bud, it quickly drains users of vigor with its calming euphoria. It dissolves all tension from the muscles, resulting in a wobbliness in one’s gait while walking toward the couch for a quick nap. However, it renders the body immobile as a heaviness in the limbs quickly turns into sleep.

The process of creating Madcow was interesting. Presumably, its unknown breeders wanted to create a Sativa-dominant strain that engulfed the body in an Indica’s soothing buzz. And, what better way to do that than to cross Purple Cow with Durban Poison? Both have high-flying Sativa highs that have been genetically engineered to produce the body-melting effects of its offspring.

Indeed, Madcow lives up to its parents’ potency but is a little bit forgiving to beginners with its buildable high. Still, it must never be over consumed especially in its concentrated form. A single toke has the power to subdue even the most seasoned of users.

    Consumers should tread lightly with Madcow. Its rapid effects manifest within minutes after the first two to three puffs. In swarming the mind with a rush of energy, it can be quite overwhelming – especially for users with unprepared for its potent THC levels of up to 20%. However, the surge in vitality should be expected of the Sativa leaning herb.

    During the initial onset, it reinvigorates users and leaves feeling many uplifted. The upbeat disposition is immediately noticeable too, as one revels in happy memories and bright ideas. The eyes twinkle while smiles grow wider and frowns turn upward. For a moment, the innate confidence that remains dormant for most of the time is roused from its hiding place. Enthusiasts engage in conversation with friends to share ideas, stories, or simply build camaraderie.

    The effects quickly wane as each hour passes. As though totally stripped of energy, a heaviness plants itself in the muscles. It intensifies with each puff until it eventually covers users in a blanket of relaxation. The body loses its rigidity as it melts like butter. The urge to kick back and lounge around in the couch grows stronger too. In all likelihood, users will find themselves fast asleep with this strain.

    Though most are capable of staying active or functional when using Madcow, it is clear that it is unlike the typical wake-and-bake Sativa strain. As such, it is best used at night where does not need to think about work.


    A single whiff of Madcow is enough to entice the senses with an interesting smell of sweet caramel and butterscotch. There is a subtle hint of earthy spice once the buds are broken apart that gradually develop into a more chemical, ammonia smell during combustion.


    Madcow is quite sweet, boasting a similar flavor to butterscotch. It is accentuated by notes of freshly-picked spices with a blend of earth. On the exhale, its acrid smoke leaves a sharp ammonia aftertaste on the mouth.

    Adverse Reactions

    Like other strains, Madcow inhibits moisture from the salivary glands and tear ducts. As such, it is not uncommon for the eyes and mouth to dry albeit only mildly. Downing a few glasses of water, as well as staying hydrated throughout the day, is usually enough to ease the ache. If anything, the worst experience users have with the Sativa-dominant herb is an increase in anxiety levels.


    About a third of cannabis enthusiasts in the United States use the herb to relieve stress. And, through the combined effects of its cannabinoids, Madcow also reduces chronic levels of the same health issue by stabilizing emotions and calming the mind. As such, the strain can also be used as an anti-depressant to manage symptoms of depression, PTSD, and other mental health issues.

    The stimulating head high also encourages a hearty appetite. And, with an equally jovial mood, users take a bite out of a meal with enthusiasm and fill the stomach with delicious food. The revived appetite is great for patients with difficulty eating due to conditions like anorexia or cachexia.

      The biggest challenge Madcow poses to users is finding seeds due to its rarity. However, once aspiring growers get ahold of it, the strain is relatively easy to grow. It boasts the typical lanky structure that many Sativa-dominant strains have, as well as a high resistance against moisture due to its airy buds.

      Outdoors, it thrives in a warm, Mediterranean areas where it can stretch as tall as it wants in the garden. However, this does not mean the bud will perform poorly in the cooler weather of the northern hemisphere. In fact, it produces a hefty yield albeit after giving it a few extra weeks to flower.

      Basic gardening techniques such as refraining from overfeeding the plant are required to grow Madcow. Apart from that, it is also crucial to provide support to its thin branches and stalks during the flowering stage. Pruning, on the other hand, will not only encourage lateral branching but also improve air, light, and nutrient distribution.

      In controlled settings, Madcow grows well in hydroponic systems. It grows faster, yields higher, and produces buds that free of pesticides. However, it may be less flavorful. If one prefers cultivating its terpenes, the best medium is soil.

      It takes a long 10 to 12 weeks for Madcow to flower fully. Once ready for harvest, the strain produces a good 12 to 16 ounces of buds per square meter.
