Grape Killer 99 Feminized Profile by Kyle Kushman

Grape Killer 99 is a beautiful plant that combines balanced yet intense effects with an exotic blend of scents. These feminized seeds from Homegrown Cannabis Co. produce a plant that’s easy to cultivate and very reliable, thriving indoors and outdoors. Under optimal conditions and care, it produces an above-average yield after a relatively quick flowering time. After harvesting, drying and curing, it’s suitable for recreational use, while also providing a host of potential therapeutic benefits.

Most of Grape Killer 99's traits are reminiscent of Killer Queen – a Killer Queen x Querkle cross. The two plants share the same genotype, and can induce a profound high that hits mentally and physically. Both have striking purple and lavender hues, with a frosty white coating of trichomes.

From Cinderella 99 (C99 or Cindy), Grape Killer 99 inherited its reinvigorating, euphoric cerebral stimulation and enhanced growth pattern, with a small, branchy structure, quick flowering time, high THC production and generous yields.

Whether for cultivation or collection, these seeds are highly reliable and come as the result of painstaking efforts in breeding, cultivating and stabilizing.

Growing Grape Killer 99 from Feminized Seeds

Grape Killer 99 is versatile plant that can grow indoors, outdoors, or in a greenhouse. It’s small-to-medium in size and has a compact structure featuring numerous lateral branches, which makes it a perfect candidate for the Sea of Green setup. An immediate benefit of this is that it cuts the vegetative period by two weeks, shortening the overall growth cycle.

Using hydroponics is an excellent option for this plant, since feeding the roots directly ensures that it has enough nutrients to sustain its explosive growth under a powerful HID lamp. On the other hand, old-school growers maintain that using organic soil is best for enriching the terpene profile. Either way, the yield after 7 to 9 weeks of flowering could be as high as 1.31 ounces per square foot.

You can grow this strain outdoors in a warm location with plenty of sunshine. Under optimal conditions, each plant can produce up to 14 ounces come harvest time, which usually falls in the first week of October.

Overall, Grape Killer 99 is a pleasure to grow and it doesn’t require any specific advanced techniques. Throughout the whole process of cultivation, the maintenance is routine: simply keep the temperature, moisture and pH levels within the optimal range. Although the coloration does not have a bearing on the effects, it does add to the bag appeal. Exposing the plant to colder temperatures during the dark cycle (before flowering) triggers the appearance of lavender hues on the leaves.

Fragrance and Flavor

Grape Killer 99 exudes the classic scent of Hashish with a twist. Blending into the earthy odor is a tropical concoction of grape and berry with sweet, spicy and citrus notes.


Striking in both entrance and exit is the best way to describe the effects of Grape Killer 99. Boasting up to 20% THC, and further enriched by a remarkable concentration of terpenes, the euphoric cerebral buzz can be felt within moments of taking a couple of hits. It quickly creates a positive, upbeat and talkative frame of mind that’s great for socializing.

The strain energizes the mind and the body, helping clear away mental cobwebs while boosting creativity, and keeping the motivation to stay productive sky high.

The buzzing mental stimulation may bring heightened sensitivity to surroundings. Some sensory and auditory distortions could also occur, such as colors appearing more vivid and sounds seeming amplified.

Before these psychoactive effects have a chance to get out of hand, Grape Killer 99’s Indica side starts to manifest around 30-40 minutes after consumption. At first, you’ll feel relaxed and tranquil, before it intensifies into a numbing buzz. As the body high becomes even more profound, a noticeable heaviness weighs down the limbs, and although it’s not likely to lead to couch-lock, the sedating effects will likely put you in the mood to chill out. At this point the cerebral stimulation also takes on a dreamy quality that’s great for quiet moments of introspection and reflection.

This strain is likely to cause an attack of the munchies, so preparing some food ahead of time is a wise idea. You won’t want to move once the full-bodied high is at its peak.

Grape Killer 99 is highly potent, and you must not go above the recommended dose. Even so, cottonmouth, dry eyes, dizziness and headaches are common reactions. Overconsumption can cause more serious symptoms such as anxiety or paranoia.


As a medicinal strain, Grape Killer 99 is said to be an excellent source of reprieve from stress. Beyond calming the nerves, it may also reduce symptoms of depression, thanks to its combination of anti-depressant properties and euphoric, uplifting psychoactive traits.

It’s also been used as a natural alternative to traditional painkillers. Its inherent anti-inflammatory and analgesic properties may alleviate chronic pains, potentially providing comfort to people suffering from fibromyalgia, multiple sclerosis, arthritis and many other ailments.

Grape Killer 99 Feminized Seeds

Grape Killer 99 lets you experience the best of both worlds. From a soaring high to an intense body stone, the benefits are not only for recreational consumers – it’s also said to be a highly effective medicinal strain that may relieve stress and pain.

Obtaining these feminized seeds from Homegrown Cannabis Co. is simple, and growing them is easy too. These high-quality seeds boast some of the highest germination rates in the industry.
