The granddaughter of Jack Herer, the bomb with a turbo sativa flavor

What do you get when you take legendary genetics, load them with fast-growing DNA, and add a few generous tablespoons of telltale citrus flavor? That’s right – finish with Grapefruit Superstar Homegrown cannabis seeds.

This fast growing 90% sativa hybrid is ready to burst out of the ground, filling the air with mind-blowing fruit scents and pure, concentrated 20% THC sativa power. Grapefruit Superstar is bound to leave a lasting impression on unsuspecting growers around the world.

See what happens when one of the best known strains in the world is renewed in Amsterdam, a couple of jet boosters and a splash of perfume to make everyone in the room turn heads.

Grapefruit Superstar Homemade Cannabis Seeds

Grapefruit Superstar is certainly one of the most fruity strains in the Amsterdam Genetics Homegrown range.

The taste of sweet and sour citrus is an overbearing part of the Grapefruit Superstar experience, but its most interesting aspect lurks beneath the surface. True to the form of homegrown cannabis, this strain represents a proud genetic heritage.

In fact, it’s blessed with some of the world’s most famous weed DNA: the strain named after the Great Guru In The Sky, Jack Herer himself.

Jack Herer x Shiva Skunk resulted in the award-winning Cinderella 99. She is a tasty lady and once we crossed her with our Superfast Growing Sativa we knew we had some good growing fruit.


Grapefruit Superstar feminized cannabis seeds contain some of the most potent sativa genetics in our entire catalog of strains. In terms of effects, this suggests a loud head buzz – and this strain definitely delivers when it comes to cerebral highs.

The brain is treated with a quick barrage of happy and uplifting vibes, which arouse talkative moods and creative inspiration. Couch lock and apathy are out of the question as long as you keep the dosage on a modest side.

Get ready for uplifting productivity with great sweet and sour grapefruit flavor!

Medical potential

In terms of medicinal applications, Grapefruit Superstar’s strong Sativa load is its main selling point. If tiredness and fatigue are holding you back, this strain is bound to refuel and recharge your mental activity. It’s a pretty effective kickstarter, so maybe this isn’t the best evening weed to try.

Interestingly, the 1% CBN content could balance this effect, adding anti-inflammatory and analgesic properties to the cannabinoid mix for further effects on the entourage. All in all, if you’re plagued with headaches after a stressful day at work, this could be a good way to soothe that pounding head.

Some report positive results using Grapefruit Superstar to counteract migraines. All in all, this is a strain worth trying for anyone looking to relieve psychological pressure, with a sensational taste and uplifting effects as added benefits.

Flavor & Aroma

We can be brief here: the spicy, sweet and sour grapefruit aromas conveyed by Grapefruit Superstar are reason enough to give it a taste. If we want to talk about terpenes here, you can bet that limonene is solidly represented in its profile.

The added spice touch is subtle, but just enough to take that citrusy experience to a new level. This strain is known to start spreading its scent from the very beginning of flowering, so when it’s ready for harvest, you’ll be in pain just to get a taste of all that exciting fruit goodness.

Indoor growers are advised to check and double-check their carbon filters while growing, as things can get smelly in confined spaces.

Grow Info

In fact, Grapefruit Superstar Homegrown seeds were explicitly designed with avid sativa growers in mind. One major drawback of sativa genetics is their prolonged flowering time. Well, we managed to nip that problem in the bud – this is where our Super Fast Growing Sativa comes in!

For a 90% sativa hybrid, a flowering time of 8-9 weeks is pure luxury. Maybe you can even squeeze in that second outdoor grow this year? If you prefer the indoor approach, keep an eye out for overgrowth spikes.

Keeping this female under one meter isn’t hard indoors, but out in the garden, her sativa-growing potency could push her to grow up to 3 meters tall, just for what you know.

Grapefruit Superstar feminized seeds are your affordable ticket to a 99% female plant. Its strong genetic makeup provides good protection against adverse conditions and parasites. She’s also a flexible strain – she can do well even in sub-optimal lighting, and if you treat her right, she’ll produce an excellent harvest both indoors and outdoors.

Outdoor yields are usually only slightly less impressive than indoor yields, which are nothing to sneeze at, coming in at around 450-500g per square meter.

In fact, it’s not that difficult to reckon. Finding a sativa hybrid of this caliber, with a unique taste and a nice range of effects, is hard enough.

Getting one with this level of resilience and such dizzying growth and flowering speed is next to impossible – except when you get your Amsterdam Genetics Grapefruit Superstar cannabis seed pack right now and start growing!
