Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10-14 weeks. Great for new growers, small spaces, and multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Grapefruit Marijuana Origins

When Cinderella 99 met an unnamed grapefruit-flavored sativa, the result was an uplifting mood-lifting strain with a somewhat tropical effect. A creation of Nectar Seeds, Grapefruit produces a dream-like body high that leaves your entire body floating in pleasant productiveness. These noticeable effects come from a tiny plant, which surprisingly stays small while delivering reliable yields.

THC levels typically average between 15% and 22%, but this may vary depending on the environment and the grower's skill.

What Are Grapefruit Auto Seeds?

Grapefruit autoflower seeds include Ruderalis genetics. That means they can transition from vegetative to flowering with no outside assistance, making these marijuana seeds incredibly easier to grow. Ruderalis genetics also make the plant more hearty. Cannabis ruderalis is native to Siberia, Russia, where it evolved to survive extreme conditions.

Growing Grapefruit Autoflower Seeds

Grapefruit marijuana plants are naturally small, with colorful details once flowering that remind you of a citrus plant. It is sativa dominant but grows dense like an indica. The cones are also dense, despite their sativa-esque shape. When growing Grapefruit auto seeds, leave plenty of room for horizontal spread. Because it is an autoflower, your plants will stay short, whether indoors or outdoors.

Preferred Climate

Grapefruit marijuana plants prefer a warm (mediterranean or tropical) climate. Indoors the plants should be kept under humidity levels of around 50% and stable temperatures near 80 degrees Fahrenheit. Outdoor growers can grow anytime the temperature will stay above 80 degrees until harvest.

Grapefruit marijuana is a daytime cultivar that will not cause couch lock and is unlikely to cause excessive anxiety. Dry eyes and mouth are typical, as well as the chance for headaches. While unlikely, those prone to anxiety should use moderation when enjoying this strain.

Grapefruit Cannabis Smell and Taste

Earthy, skunky, and citrusy all describe the aroma of this strain. Cinderella Indica genetics mixed with a limonene-kissed Grapefruit produces noticeably tart notes that bring a smile to your face. Beneath it is a hint of sweetness that clearly reminds you of fresh sour grapefruit.

The taste is just like the aroma. Sour grapefruit meets your tongue; however, there's just enough sugar on top to make it work. It's a pleasant treat that always seems to surprise you.

Uses for Grapefruit Cannabis

Grapefruit enhances mood and gives you energy with a fruity, sour smoke. This makes it the perfect start of the day strain for those that struggle with motivation. It's also a social strain that will promote creative ideas and talkiness. The energy boost is noticeable but not excessive; most people will not experience high anxiety levels.

The sativa effects in this strain are noticeable but not overpowering, which is why Grapefruit is a good strain for overall relaxation. A favorite for managing stress and anxiety due to high amounts of pinene, this citrusy strain is perfect for encouraging positivity and focus.
