Blockhead Marijuana Strain Review

Strain Overview

The Scoop: This Amsterdam classic was originally cultivated using some extremely rare genetics, including a candy-like Sweet Tooth male strain and an unknown female of potent Indica origin.  Appropriately named, this strain was anointed with the Blockhead moniker for a reason – her powerful cannabinoids provide that heavy-headed feeling.

The Result: Blockhead provides an energized buzz that inspires creativity while providing a touch of Indica relaxation. This strain allows today’s aficionados who prefer the Indica high to get their buzz on while still maintaining the necessary motivation to make it through the 9-to-5 workday.

The Verdict: Blockhead is a wonderful Indica-dominant strain that has some awesome prominent Sativa qualities. She gives you a nice cerebral buzz while providing a light body high, which is really nice, and provides a well-balanced high for those looking to enjoy a light Indica during their work day.

Strain Profile

The Science: Blockhead’s mysterious maternal gene pool was originally selected and crossbred with her Sweet Tooth father, cultivating a distinctly unique strain. This rare one-off strain enjoys a distinctive flavor profile thanks to her unique terpenes and flavonoids – ultimately creating a connoisseur’s delight. Maintaining a total active cannabinoid content of 20.66%, 20.61% came from Δ9THC and THCa. Also of note, Blockhead has zero CBN and only .05% CBD.

Appearance: The Blockhead strain maintains large, thick flowers, which strongly resemble the natural shape of Mother Nature’s pinecones — spiky calyxes that litter flowering brackets. Accented with deep hues of lavender, Blockhead’s flower enjoys an almost glowing fluorescent greenish-yellow hue. Like waving a red cape in front of a charging bull, her ruby red pistils motivate today’s connoisseur to take on her psychoactive compounds. No doubt, a colorful flower to admire, her vibrant coloration is only outmatched by her immense trichome coverage. 

Consistency: Blockhead enjoys an incredibly dry yet viscous consistency. When properly cured, this strain remains masked in sticky THC-laced trichomes capable of turning anything that comes into contact with this messy girl into a resinous wasteland. Popular amongst patients and recreational smokers alike, this strain remains infamous for her hard-to-shred flowers.

Scent: Cracking open the airtight seal of her mason jar, Blockhead releases her sourish, grapefruit-like, chemically astringent and brown sugar laced aroma. Quickly reeking up the room, her stink can fill the entire house in no time. Once broken open and properly shredded, her chronic nuggets emit the pungent aroma of sweet melon, papaya, and a subtle hint of birthday cake. Once lit … be prepared. Chances are you may get an unexpected visitor drawn in by the heady aroma.

Taste: After taking a sizable rip off the daily driver, experienced smokers can taste her sweet and sour terpenes — a complex mix of a lemon and candy-like notes that makes your taste buds go crazy. When exhaling the hazy cloud, consumers can quickly pick up on the hints of kiwi, mint, watermelon, and Royal Riviera pears. When all is said and done, Blockhead leaves an intriguingly sour and fruity taste lingering on the palate.

Effect: Blockhead has a disconnected, heavy-headed type buzz, hence the name. Enjoying a full-bodied Hybrid effect with a nice cerebral buzz, this strain provides a light body high that eases any tension in the body.

Strain Background: Blockhead is a distinctive and uncommon strain with an undetermined patriarch. A very rare and special strain, Blockhead hails from the capital of the Netherlands – Amsterdam. 

Medical Uses: An excellent strain for mitigating painful headaches, quieting apprehension and anxiety, relieving desolation and dejection, increasing appetite, relieving muscle pain and menstrual cramps while simultaneously stimulating our creative impulses.
