Harpoon Rock Feminized Marijuana Seeds

The Sativa-leaning Moby and the Indica-dominant Do-Si-Dos sit on opposite ends of the cannabis spectrum, but they share a number of similarities that got them to top-shelf status. Both create an incredibly potent and euphoric high, with potential therapeutic effects. They're heavy-yielding plants that ensure a fruitful cultivation journey. With such traits, blending their genetics was sure to create a winning cultivar.

Harpoon Rock retains Moby's highly psychoactive influence and lofty height. Home cultivators should not worry about the latter, though, because the plant's stretch can be limited through training.

Harpoon Rock is a highly psychoactive cultivar with an average THC concentration of around 20 to 24%. Its strength delivers a profoundly euphoric buzz after just a hit or two, potentially help-ing combat stress, anxiety, and depression. Accompanied by a subtle psychedelic twist, the cerebral high inspires creativity as well, making it useful to artists in need of fresh ideas.

Harpoon Rock is a great daytime cultivar as its stimulating mental effects come with an energy boost that can beat fatigue like a drum. It also comes with a mellowing influence as the high begins to wane. If too much is taken, the body buzz can become numbing and the cerebral effects can turn trippy. Regardless of the physical impact, medical marijuana patients have reported the benefits of its pain-killing and anti-inflammatory properties.

Marijuana enthusiasts with high THC tolerance and mid-level cannabis cultivation skills are the perfect target audience for Harpoon Rock. Plants grown from Homegrown Cannabis Co.'s feminized seeds thrive indoors and out and are heavy-yielding as long as they're grown in a reasonably favorable environment. An all-female crop helps eliminate the hassle of gender segregation that comes with mixed-sex grow operations, without affecting the yield potential.

Growing Harpoon Rock Feminized Seeds

Feminized Harpoon Rock seeds have identical growth patterns and thrive under the same conditions as regular cannabis seeds. They don't require special care or additional nutrients, but they must be protected from prolonged stress to prevent them from developing hermaphroditic tendencies.

Harpoon Rock may not have the beastly yields of Moby, but she still puts impressive numbers on the scale. The plant has the easy-to-handle needs of Do-Si-Dos, giving growers with moderate experience in weed cultivation an uncomplicated yet gainful experience. Her bushy foliage will need to be trimmed and pruned, which will help the regulation of airflow and light penetration. If mismanaged, problems like mold, mildew, and pests may arise.

Besides thinning out the leafage, regularly check the pH level of the medium from vegging up to the last feeding. The ideal pH is around 6.0 to 7.0 for soil and 5.5 to 6.5 for soilless systems. Harpoon Rock does well in any substrate with a suitable pH and PPM. If you don't have an existing setup, bear in mind that soil enhances the terpene profile, while hydroponics promotes vigorous growth.

Growers can perform training techniques to keep Harpoon Rock's size under control. With her branches bent or tied down to a mesh, the Screen of Green (ScrOG) technique forces the plant to grow horizontally. This exposes her flowering sites to equal amounts of light, allowing them to develop optimally. The wire also supports her limbs, preventing the branches from breaking under the heavy colas.

Topping can also be used. This requires pinching or cutting the plant's crown or main growth tip, which prevents apical dominance, encouraging the plant to bush out instead of growing upwards. This method also improves the yield potential and is commonly combined with the ScrOG for even better results.

Harpoon Rock is especially prolific when grown outdoors in a sunny, warm, and dry location. She thrives in places with a Mediterranean-type climate, such as California and Southern Europe. If grown in a favorable outdoor environment, cultivators can collect up to 21 ounces per plant. Har-vest rolls in around October in the northern hemisphere and April in places south of the equator.

Raising Harpoon Rock in a well-regulated climate-controlled grow operation can be just as re-warding. It flowers for 9 to 10 weeks, producing up to 1.6 ounces per square foot. Keeping the RH level and temperature within suitable parameters is important: during the vegging period, these should be 45 to 55% and 69 to 77°F, respectively. Lower to 35 to 45% and 68 to 75°F as the plant starts popping nugs, and decrease the nighttime temperature by a few degrees through-out the lifecycle.

Fragrance and Flavor

Harpoon Rock's flowers emit a woody, piney funk thanks to the White Widow lineage that comes via Moby. A closer sniff reveals subtle incense notes, which get more robust when lit up. The smoke is pretty smooth, so it doesn't typically set off a coughing fit or cause watery eyes.


Harpoon Rock's potent effects are no joke, and are best reserved for tokers with incredibly high THC tolerance. The effects are mainly head-focused and cerebral, seizing control of the brain almost immediately after the first hit. It ushers in waves of euphoria, followed by ripples of creativity.

At the same time, Harpoon Rock brings a boost of energy that, while strong, will not send you bouncing off the walls. The physical hit strikes quickly, providing enough motivation to keep you up and on the go for hours.

The vigorous high is an excellent match to the cerebral buzz. Both take quite some time to subside, carrying on well into the afternoon if enjoyed around midday. As the high begins to wane, the bodily influence shifts from enlivening to calming. Some tokers may even space out and become deeply introspective and immersed in their own thoughts.

In higher doses, couch-lock may occur, and it may come with adverse effects such as dizziness, increased anxiety, or paranoia. Dry eyes and cottonmouth are common due to the cultivar's high THC content. Casual users and beginners are especially susceptible to unwanted reactions so it's really important to stick within personal tolerance levels.

Feminized Harpoon Rock Seeds

Artists, recreational users, and medicinal patients looking for potency with a dose of cerebral magic are in luck with Harpoon Rock. These buds are best used in the mornings and do not cause lethargy in average dosages. By using these feminized seeds from Homegrown Cannabis Co., cultivators can collect up to 1.63 ounces per square foot indoors or 21 ounces per plant out-side, ensuring a big enough stash to last a number of months.
