For many years, Dutch commercial growers Dick and Freerk stuck to their standard marijuana strains of Power Plant and Amnesia. Like the vast majority of commercial growers, the two worked with clones from their own mother plants, but every now and then they would try new strains by sourcing the respective seeds, growing them and checking to see how their customers liked their new kinds of buds. On the rare occasion, they hit the jackpot.

Some time ago, a grower friend of Dick and Freerk‘s named Cloudz gave them a clone of Dinachem, a strain by Dinafem of Spain. This Spanish seed company had earned itself a big name in the worldwide seed business over the past 10 years. “You should really try this one,” Cloudz urged.

Since Dick and Freerk viewed Cloudz as someone well-versed in the world of cannabis strains, they happily accepted his recommendation, which was actually trickled down to him by yet another experienced grower named Growolf, based on a package of feminized Dinachem seeds.

While that Dinachem cutting grew into a mother plant in Dick’s and Freerk’s veggie room, they started to look into the mysterious strain that had been unknown to them up to that point. That’s when they discovered some interesting details: Dinachem consisted of nothing less than original ChemDog 91 genetics. Everybody a little bit familiar with cannabis strains has heard of ChemDog—these exquisite genetics created in 1991 by the breeder of the same name in east coast US are simply legendary.

Like only a few other strains, it has put its stamp on the seed-breeding business. Back then it was the first kind of marijuana on the American market. The strong, basic note that amazingly smelled like fuel, complemented by citrus and conifer notes, was a real aroma revolution.

And, as a parental plant, ChemDog later gave birth to other strain legends such as NYC Diesel, Sour Diesel and OG Kush, just to name a few. The ChemDog descendant OG Kush is a phenomenon on its own; it’s arguably the most influential and important variety in recent years on the international seed market, as it was and is used for countless crosses and breeding projects, some of which have been showered with awards.

While there’s no end in sight yet to that huge OG Kush hype, the problem with the original ChemDog 91 is that it’s a clone-only plant and not an actual seed strain, only being available in the form of female cuttings. So a seed company striving to offer ChemDog 91 genetics in the form of seeds has to be in possession of that female elite clone as well as male plants of a strain preferably closely related to it so that through multiple backcrossing, the breeder can approximate the ChemDog 91 genetics as close as possible.

Discovering Dinachem

Dinafem in Spain received the original ChemDog 91 clone genetics directly from the ChemDog breeder, and in addition, plenty of GuavaChem seeds, a stabilized great-great-grandchild of ChemDog 91 bred as a seed strain by ChemDog over many years. It genetically resembles ChemDog 91, thus being a perfect backcross partner for it as well as being a perfect rejuvenating cure.

Due to the old age of the genetics—vegetatively propagated again and again over decades—original ChemDog 91 clones grow slowly nowadays and don’t yield well any longer. But, if transferred into seed form by means of related genetics such as the GuavaChem, it gets refreshed, regaining power and productivity. The lost vigor comes back; it’s a bit like an invigorating autohemotherapy.

Dinafem chose the most stable GuavaChem plants of the highest quality to cross with the original ChemDog 91 cutting, thus, over several generations, creating the vigorous, high-yielding Dinachem strain (65% sativa, 35% indica).

The smoke from the Dinafem strain delivers an extremely powerful turn, which is cerebral, euphoric and uplifting at first, then finishes with a relaxing body high. Both sides of the spectrum—sativa and indica—are well-expressed in Dinachem’s kind of high. Special emphasis was also put on the breeding goal to preserve that special penetrant fuel/diesel or petroleum trademark aroma of ChemDog, but also those other olfactory attributes typical of that strain, hints of citrus and pinewood are all in there!

Dinachem needs about 60 days of flowering to ripen, yielding up to 500 grams of chubby buds that, despite its sativa-dominant genetics, reminds users more of an indica than a sativa. Medically, this strain can do wonders for people suffering from stress, anxiety or inner restlessness, and it can also act as a great analgesic, relieving even chronic pains.

Growing Dinachem

Back to Dick and Freerk. After they had learned more about Dinachem, they were fired up and full of sizzling anticipation for the forthcoming Dinachem bud premiere. The first cuttings they produced rooted without any problems and after 10 days in the veggie stage they were put to flowering. Eight and a half weeks later, the plants had fully matured, and there it really was, that incredibly intense and complex odor mix of fuel, citrus and pine. “When one reads about such an usual aroma description, it comes across as remarkable, but having this green olfactory artwork in front of you then and actually smelling it, really is astounding and fascinating,” says Freerk. “The buds were extremely resinous, thick, roundish and tight, making for big yields. ”

Testing Dinachem

When testing Dinachem for the first time, Dick and Freerk could hardly finish their small, single test joint. It was that strong. “Dinachem’s indica stone turned out to be more than tremendous; the effect was instantly there and totally steamrolled us after just a few hits so that we were stoned to the bone and could hardly move,” says Dick. “But mentally it left us totally happy and sunshiny; it gave us a broad, permanent grin. Growolf had selected a phenotype with an enormous, heavyweight indica punch, and less sativa influence than usual. With that mood-lifting effect, a part of Dinachem’s sativa side at least did come through in a very pleasant way.”

While Dick and Freerk were deeply impressed by Dinachem’s potency, they wondered what would their customers would say. After a couple of days, feedback was impressive, with people stating:

  • “Smoked it and couldn’t remember my own name after a while.”
  • “It’s like careless day-dreaming…feeling extremely stoned and relaxed.”
  • “I was just sitting and dwelling on happy thoughts.”

Other customers’ statements showed a lot of enthusiasm regarding Dinachem’s aroma and potency. There was no doubt this strain would become a part of Dick and Freerk’s weed arsenal. “It’s a great feeling to have found a new clone king after all those years,” they say.
