Jack Herer Strain

May 26, 2021

The Jack Herer strain is a sativa-dominant strain named after the legendary cannabis activist and best-selling author of The Emperor Wears No Clothes. An all-round happy, clear headed high, it makes for a suitable homage to the real Jack Herer, often described as “the perfect blend”, earning itself fans world-wide.

Sativa/Indica % Indoor Yield Outdoor Yield Flowering Period
55% / 45% 18oz/ m2 18oz/ plant 8 – 10 weeks indoors, late September to early October outdoors.

This famous strain was created in the mid 90’s in Holland, where it was bred and cultivated as a medical-grade strain. Its distinct engineering made the use of a sativa Haze hybrid, mixed with indica Northern Lights #5 and the Shiva Skunk.

Its uniqueness doesn’t just lie in its genetics, but also in its soothing, happy personality, which shines strongly in its effects. Jack Herer also does great justice to its name by being a very powerful healing aid for patients suffering from an array of ailments, both mental and physical.

Jack Herer Autoflower

Rated 5 out of 5

Jack Herer Autoflower via I Love Growing Marijuana is an excellent strain when tent grown indoors. I used a 1200 watt grow light with veg and bloom switch in a 4′ x 2′ x 5′ Mylar lined grow tent, with inline duct fan and carbon filter. I used bagged potting soil and well water. Fertilizers for lush green growth and enhanced bloom were watered in bi-weekly. Nothing was applied to the leaves. No pests or diseases were encountered. No topping or other advanced grow techniques were used. I just let 2 plants grow naturally. I began trimming off lower, quarter sized buds in 10 weeks, the largest (8″ long by 2″ wide) top buds were harvested at 12 -13 weeks. Drying was on wood slats with a fan gently moving the air for 5 to 8 days depending on bud size. Then I began the 5 week cure process in opaque purple glass quart jars. All in all, 4 quart jars, very full, loosely packed were stored. I estimate the weight to be approx 8 oz..
The fully cured Jack Herer is smooth with a mild citrus flavor. Only 4-5 puffs is sufficient to start the day with a pleasant head-high (do not ever drive while high), with exceptional arthritic pain relief. Several hours later the head-high mellows to tiredness. This is easily countered with a cup of coffee at lunch.
My hubby and I have found Jack Herer Autoflower from I Love Growing Marijuana to be a favorite for an easy and abundant tent grow. It is our ‘go to’ for daytime use, dry mouth being the only negative side effect. This strain is quite medicinal in its arthritic pain relief and waking mood enhancement.

    I have lost seeds to Customs twice, and I'm afraid of name recognition. Although my Brother, that lives near me, has had no trouble in receiving seeds. Advice appreciated. Thank You, Lynwood
