Growing The Fastest Jack Herer Haze Marijuana Strain

I highlight individual cannabis strains only when their performance is truly amazing. Your grow op is valuable to you, and you only want to grow reliable, superior strains. That’s why I work hard to find the best strains and tell you about them.

Last time I counted, there were at least 975 named cannabis strains offered by seed and clone companies worldwide. Obviously I haven’t grown all or even most of those strains. However, I have grown strains from more than a hundred marijuana seeds companies, and I network with growers who’ve grown strains from dozens of companies different than the ones I’ve bought from.

I also do investigative journalism by contacting marijuana seeds companies and asking about their marijuana genetics, breeding program, seed germination rates, phenotype consistency and customer service policies. What I’ve discovered is that a disappointingly small number of marijuana seeds companies are professional and legit.

The marijuana seeds industry is a totally unregulated industry–anybody can chuck some pollen at female flowers, harvest the seeds, call them Blue Dream, Silver Haze, OG Kush, Chemdawg, Lemon Skunk, or some other popular name or variation thereof…and sell them. There’s a lot of grifting and corruption. It’s a seedy industry.

You deserve to get the results advertised when you invest your valuable money, time and risk growing weed.  The good news is you can look to Growing Marijuana Perfectly to discover the finest cannabis seed strains and breeders.

The Fastest Jack Herer Haze Ever

Take a look at the beautiful buds and compact stature of the Jack Herer strain in this article’s photo. It was bred by Dutch Passion–one of the foundational Dutch cannabis seeds companies. They were making marijuana seeds 30+ years ago when the only marijuana seeds companies were in The Netherlands. Their founder helped pioneer autoflowering and feminized seeds. Even after the Dutch government became right-wing and anti-cannabis in the early 2000s and started trying to shut down Holland’s cannabis coffee shops and grow ops industries, Dutch Passion stayed in the game, preserving its rare genetics, mother plants, and male pollen plants.

I’ve tested 17 Dutch Passion seed strains in the last five years. Almost all have been high-quality strains. Some have been absolutely wonderful. Their Auto Cinderella Jack is one of the wonderful ones. I’ve germinated nine Autoflowering Cinderella Jack seeds from different seed orders in the two years and had 100% germination rate, and the plants have grown out to be identical to each other. That kind of germination rate and phenotype consistency is very desirable, and very rare.

Auto Cindy Jack was created by a Dutch Passion breeding project in concert with Spain’s Buddha Seeds company, another breeder known for creating quality cannabis seeds. Dutch Passion told me their company likes to work with top-rank collaborators such as Jorge Cervantes, Buddha Seeds, The CBD Crew, The Joint Doctor and others who know how to do creative breeding of exceptional cannabis strains.

The Dutch Passion team approached Buddha Seeds because Buddha was an early European pioneer in developing high-yielding autoflowering strains. The project goal was to make a super-strong autoflowering marijuana strain, with very high levels of THC. The team selected original Jack Herer and Cinderella 99 strains as their core genetics for this new project. These are notable old-school strains with distinctive highs. They’re easy to grow, high-yielding, stable strains.

Jack Herer is a legendary Haze hybrid that includes genetics from the also-famous Northern Lights and Skunk strains. It’s very popular in part because it has high resin production, powerful Haze taste and scent, a complex high, and relatively heavy yields, with all the psychoactive characteristics you expect from a real Haze.

Dutch Passion told me professional lab analysis was used at each stage of breeding to confirm high-THC foundation genetics during the lengthy Auto Cinderella Jack breeding project. Photoperiod Jack Herer and Cinderella 99 plants were interbred with Buddha’s “Magnum” autoflower genetics.  Magnum is a 3-way Sativa-dominant autoflowering hybrid that’s usually ready for harvest  85 days after seed germination. Dutch Passion has tested dozens of Auto Cinderella Jack plants and found THC levels always higher than 20%. Apparently, the breeding program succeeded!

Growing Auto Cinderella Jack Outdoors & Indoors

I’ve grown nine Auto Cinderella Jack plants from seed. It’s important to note that the seeds were ordered at different times over a two-year period, because the 100% germination rate and uniform phenotype consistency I got from these plants indicates that multiple batches of seeds were very strictly quality-controlled.

With some seed companies, I’ve ordered a strain and had one batch of seeds perform as advertised, but plants from seeds from a different order of the same strain performed miserably. This shows that that particular seed company doesn’t have good quality protocols. What’s worse is when a company like that refuses to refund you or provide a replacement set of seeds that grow properly. I’ve never had any of these problems with Dutch Passion.

I grew four of the Auto Cindy Jack plants outdoors, using soilless mix and white-colored cloth pots. Outdoor growing is a serious test of a strain’s resilience and stamina. Autoflowering plants do best with 20 hours of light per day from start to finish. In my outdoor grow op, they received at most 7-10 hours of direct sunlight per day, and only a couple of hours of dawn and dusk indirect, ambient light each day. They were subjected to rain, high winds, rapid temperature variations, aphids, spider mites, caterpillars, extreme heat, and gray mold. I foliar sprayed the plants with Rhino Skin (a potassium silicate formula) and rosemary extract to help armor them against pests and harsh conditions.

It’s my opinion that Auto Cindy Jack is partially resistant to sucking insects such as mites and aphids, and to gray mold. Other strains grown in the same outdoor location were much more likely to attract and be severely damaged by these attackers.

Under tough outdoor conditions, the plants did very well. They showed pre-flowering within 2-3 weeks of germination and peak bloom arrived a week later. I often top autoflowering plants, but given the harsh conditions these were experiencing, I let them grow naturally. Their natural shape wasn’t the Christmas tree or single-cola shape one often sees. Instead, they had a large main cola, grew into round bushes between 3-4 feet high at maximum height, and had a dozen or so main sub-colas on the top tier of growth and several more colas arrayed lower on the plant. The plants all looked and performed exactly the same—which is a rarity.

Dutch Passion said breeding for the highest possible THC percentages was their main goal for this strain, so they didn’t pay much attention to breeding for taste and scent, but I found the Cindy Jack taste and scent to be a delightful and potent mix of pine, turpentine, sandalwood, and fruit. Depending on what time of day and what time of bloom phase, a distinctive Haze smell was present in varying degrees.

For the first couple of weeks after flowering started, the buds looked scraggly and hempy. I was worried they might be dud buds. But all of a sudden the buds started to fill out beautifully, with minimal leaf in them, some as long as 6-7 inches with a diameter of up to two inches. Resin gland percentages were off the charts, and the buds reminded me more of Cinderella 99 buds than Jack Herer buds.

My harvest window outdoors was 81 to 93 days after germination, which is slightly longer than what Dutch Passion estimates. The highest-yielding plant gave me 115 grams of premium bud, while the lowest-yielding gave me 83 grams. These were impressive yields for low-maintenance plants grown outdoors that didn’t receive anywhere near the 20 hours of light per day which is the optimum light dosage for autoflowering.

I grew five Auto Cinderella Jack plants indoors in soilless mix in irrigated hydroponics system under 19 hours per day from LED grow lights, with UV-B light added during the last three hours of lights-on every day beginning with peak bloom. They showed pre-flowering slightly earlier than the outdoor plants did, grew faster, and were bushier but also taller, with the tallest plant three inches above four feet.

I topped the indoor plants when I saw pre-flowering but it made little difference in morphology—the plants grew out pretty much the same as the outdoor pheno did—multiple-cola with a thick, taller main cola. The smell of the indoor buds was identical to the scent of the outdoor-grown, but the indoor buds were longer, stickier, and larger in diameter than the outdoor buds had been.

The earliest indoor plant was ready for harvest 86 days after germination. The last one I harvested 96 days after germination. The lowest indoor yield per plant was 92 grams and the highest yield was 131 grams.  This is very worthwhile harvest weight from autoflowering plants that only took about three months for their entire life cycle. I was also glad that these buds needed minimal trimming, because there was so little leaf in the buds.

In grow phase, which only lasts 2-3 weeks for autoflowering plants, I used Advanced Nutrients Connoisseur Grow, which is the most cannabis-specific grow phase fertilizer on the market. In bloom phase, I used Connoisseur Bloom, along with Advanced Nutrients Big Bud, Bud Candy, and Nirvana. I flushed the indoor plants for one week before harvest with Flawless Finish. I didn’t flush the outdoor plants because heavy rains had been flushing their root zones all along. Auto Cinderella Jack is a moderate feeder. When I applied the manufacturer’s full recommended dose of bloom phase nutrients and supplements, which totaled out at around 1200 parts per million, it created leaf tip burning, so I backed off to about 800 parts per million, and alternated with a mini-flush every third feeding.

I grow at least a dozen or more of the top cannabis strains per year, and I have a very strict and detailed way of evaluating psychoactive effects and desirability. The Auto Cinderella Jack produces a very long-lasting and pleasant high, reminding me of some of the more Indica-leaning Jack Herer phenotypes I’ve grown and used. It isn’t a high for novices, but it does have medical benefits such as anxiety relief, euphoria, and increased energy. The taste of buds vaporized and combusted is heavenly, as is the Hazey smell of the stored buds.

I’ve grown several photoperiod Jack Herer strains, including the alleged original, made by Sensi Seeds. These strains all cost more per seed than Auto Cinderella Jack, and some were regular seeds rather than feminized, which increases overall costs of using those strains instead of an autoflowering variety.

These other seed companies stipulated a 50-75 day bloom phase for their Jack Herer strains. That broad bloom phase range indicates what I discovered—those Jack Herer strains are likely to have 3-5 phenotypes that range from Indica-dominant to Sativa-dominant, and with varying degrees of authentic Haze/Herer scent and high. Contrast this with Dutch Passion’s Auto Cinderella Jack, which only produces one phenotype.

Those photoperiod Herer strains took longer from seed to harvest than did the autoflowering version from Dutch Passion, but the yields weren’t significantly heavier, nor were the psychoactive effects significantly more enjoyable. Given that the autoflowering strain produced only one phenotype and was easier to grow, I’ll probably grow it rather than a photoperiod Jack Herer the next time I want some Herer magic. I want to also share with you that this autoflowering Jack Herer outperformed two other autoflowering Jack Herer strains made by other seed companies.

Of all the strains I’ve grown recently, this Dutch Passion winner is in my top three because it’s easy to grow, phenotype-reliable, high-yielding, goes from seed to harvest in a little more than three months, comes from all-female seeds, and produces a kind high.

Auto Cinderella Jack is yet another autoflowering strain from Dutch Passion that is as worth growing as a photoperiod version of the same strain type. If you love Jack Herer and/or Cindy 99, get some Auto Cinderella Jack seeds and have an easy grow that gives you the best of both.
