Jack Flash Strain Review – Bonza Blog

For decades, Sensi Seeds has been one of the most reputable seed banks in Europe. More than the number of years, it is the kinds of strains they developed that has catapulted them to being one of the elite breeders in the world. Among their inventory, one of the best is Jack Herer. Can they make a better version? Apparently, they did, or least they developed a new one with its strengths.

Sensi Seeds developed Jack Herer, a mostly-Sativa strain with the rich resin production typical with Indica plants. To that end, they succeeded with flying colors. Not only does it induce a clear head high, but it was also widely accepted by medical cannabis users. In fact, Dutch pharmacies acknowledge it as medical grade.

In developing a new hybrid using Jack Herer, Sensi Seeds picked Super Skunk, a hybrid they developed by backcrossing Skunk #1 to its Aghani Indica roots. Another strain they used is the high-energy Haze. Both the Skunk and Haze family, as cannabis fans know, are among the most prominent lineages in the world of marijuana. It is also fitting that the breeder uses these legends to bring out the best of Jack Herer.

As a result of the three-way cross, Sensi Seeds developed Jack Flash. Think of it as a more balanced version of Jack Herer on overdrive. Under the expert hands of the breeders at Sensi Seeds, and along with its prominent genetics, the strain took top honor in the 1998 Dutch High Life Cup after its release.

Jack Flash leans a little towards its Indica side. Still, the Sativa effects it delivers remains potent. Not only that, it manifests itself in no time at all. In essence, this strain is the epitome of the superhero Flash.

As soon as the first toke, the lightning fast strain delivers an electrifying sensation that enhances the mood. More than just uplifting the spirit, it goes on to induce an intense euphoric cerebral experience. As such, recreational users who have trouble clearing their head in the morning can use this perfect wake-and-bake hybrid.

For the duration of the Sativa high, users feel energetic and motivated. Getting up and running in record time becomes the norm rather than the exemption. Of course, that is dependent on how much one uses. After all, there is still more to come.

Soon after, the Indica side of Jack Flash starts to ebb down to the body. Once it does, it begins by providing a soothing sensation that wipes out tension from the body. In turn, this leads to a full-body relaxation without causing anyone to feel lethargic. However, use too much, and Jack Flash may quickly put one on a couch-lock.

Medical Use and Benefits

Jack Flash, distributed as a medical cannabis strain in Amsterdam, brings comfort to people in need. Not that it possesses a high enough CBD to be used as a treatment, but it is the psychoactive properties that have the most value.

Because of its lightning-quick ability to induce an uplifting and euphoric buzz, it is potent in wiping out stress. Consequently, people with depression and other forms of similar mental issues can take advantage of it. Already, it is difficult to cope with such conditions, but Jack Flash can quickly enhance the mood.

Use the strain in moderation, and it delivers an energy boost to combat fatigue. Even when the physical effects set in, so as long as one uses only a small amount, then it can provide relaxation without the laziness. However, use a little more, and the sedating qualities of the Indica side become conducive to sleeping. In this case, it becomes useful to insomniacs.

Growing Jack Flash

The effects Jack Flash delivers are over-the-top fantastic. Be that as it may, it is also not an easy-to-grow strain because it does require more attention and advanced techniques.

Indoors, the best way to cultivate it is to use hydroponics and combine it with the Sea of Green training method. Because of the cramped space, growers will have to prune and trim the leaves regularly. At any rate, it is ready for flowering between 8 to 10 weeks. Come harvest time; each square meter can have a yield of up to 450 grams of buds.
