Fast-Flowering Chem Genetics with Exceptional Potency

The Fast Version Chemdog Seeds combine OG Kush and Sour Diesel with Ruderalis to create a feminized, fast-flowering photoperiod cultivar. Fast Version does not mean autoflower. Indoors, you will still need to change the light to make the plant start flowering. It only has a bloom period of 49 to 63 days.

You can control the vegetative time and which size you want, and still get a quicker finish than many other photoperiod seeds. Seedkeepers have classified this strain as an indica dominant with a THC content of 22% to 32%. With high yield resinous flowers the garden appeal is considerable.

Genetics

The lineage is OG Kush x Sour Diesel x Keepers Ruderalis. OG Kush brings earthy pine/lemon/fuel and physical weight. Sour Diesel adds sharp gasoline and tangy citrus, and a more stimulated mental character. In this case, the ruderalis component shortens the flowering time instead of making the plant fully automatic.

Seedkeepers has classified the result as indica but the parents provide a good useful contrast. Sour Diesel makes the opening bright and lively, while OG Kush helps the experience settle into a calm and sleepy finish. The most strong influence of each side will be determined by the phenotype and serving size.

Chem, Lemon, Earth, and Resin

Expect a heavy smell. Sour fuel and chemicals form the base and are accompanied by lemon peel, pine, moist earth, herbs, or pepper. Some descriptions of related genetics mention something like raspberry sweetness, but Chem and Diesel are the main impressions: stronger, sour and unmistakably old-school.

Seedkeepers has not published a terpene analysis for this selection, so the final balance is subject to change. A careful dry and cure may bring out some brighter citrus or berry notes under the heavy fuel. Indoor growers should implement good odor control before the flowering period. This cultivar does not wait until harvest to announce itself.

Very High Potency, Uplifting to Sleepy

THC is estimated at 22% to 32% and CBD is below 1%. The wide range more likely represents differences in phenotype and environment, but even at the lower end it is potent. Chemdog Fast Version is of best use to experienced consumers.

Smaller quantities may keep more of the uplifting, mentally active side, while larger servings can bring the sleepy edge forward. On paper, that makes it a flexible early-evening option: engaging at first, then progressively calmer.

Tolerance, setting, harvest timing, and consumption method can change the experience significantly. Start low, particularly with flower that may express close to the top of the stated THC range.

Chemdog Fast Version has the potential to be a great beginner project. These are recommended for all experience levels. Also, if you would like to control your plants' light cycle, this cultivar is perfect as you are able to grow vegetative longer for more training opportunities, or keep it short, to have a more compact canopy.

When it comes to height regulation on these Chemdogs, you should expect around 47.2 inches. However, this can be altered by the size of the container you decide to grow in, as well as the timing of your light cycle. It is also important to switch the top of your grow container to allow for more air flow so that you can control the humidity, especially since these plants become resinous once flowering has started.

The flowering period ranges from 49-63 days. If you plan on running multiple indoor cycles, or have a specific outdoor harvest window you may need to harvest during, this is a great range to have. Of course, it is important to keep in mind that you cannot judge the maturity of these plants simply by the calendar. The flowers will dictate when it is time to harvest, and the plant will ultimately tell you when it is time.

Yield Potential and Outdoor Usage

Seedkeepers estimates yields of indoor production at 1.6 ounces per square foot and outdoor production at 17.6 to 21.2 ounces per plant. The above yields are estimates based on favorable conditions and may not represent real-world conditions and realistic operational capacity.

Numerous factors impact the yield such as light, climate, space for roots, nutrients, length of the vegetative stage, phenotype, and the skills of the grower. Outdoors, the 49 to 63 day range for flowering periods may limit exposure to cold or rainy weather at the end of the season, so select an outdoor site that is sunny and has good drainage as well as consistent airflow. The height of the plant is listed at 47.2 inches, however, the actual height may vary depending on the growing conditions and duration of the vegetative stage.

Who is the Ideal Buyer of the Chemdog Fast Version?

This cultivar is ideal for growers that want to have photoperiod control without an extended wait for flowering. This variety also has a low difficulty rating, shorter than average height, a quick finish, and the potential to yield extremely highly. Customers receive a THC content of 22% to 32% and a vintage mix of sour diesel with notes of lemon, pine, and earth.

The Chemdog Fast Version is the best choice when speed is a priority above automatic flowering. It provides the control of a photoperiod plant in terms of scheduling while significantly shortening the bloom phase, all combined with an intense fragrance and high quality from the OG Kush and Sour Diesel lineage.
