Why should I buy Auto GrapefruitZ cannabis seeds?
- Auto GrapefruitZ produces medium to large plants and is an easy autoflower strain to grow. She has strong, powerful branches and responds well to various growth techniques for training and manipulation.
- She is a Sativa-dominant hybrid with an average autoflower seed-to-harvest time of 11–12 weeks and a large XL yield.
- Auto GrapefruitZ produces large, full blooms that often display pink and purple hues on the leaves. Combined with the thick white resin layer and high potency, this creates excellent bag appeal.
- This THC-rich autoflower falls into the ‘Very High’ potency category alongside an intense fruity terpene profile with both sweet and sour fruit notes. This is a real fruit cocktail that is delicious to vape or smoke. The hybrid high is energetic, uplifting and relaxing — a pleasant combination for everyday use.
Auto GrapefruitZ has a fresh, sweet and sour fruit aroma, with a generally sparkling, sour fruit flavour — a unique terpene profile that is best described as a tropical fruit cocktail
Auto GrapefruitZ has a complex and diverse terpene profile. The different phenotypes genuinely have something to offer everyone. In general, the fruity, sour and candy-like profile dominates, but there are also plants that show very sour and more chemical notes. Other plants have a more minty, citrus-dominant fruit profile.
Some buds also display stronger earthy and woody notes — sometimes even a little towards an earthy sour kush — but overall, still very distinctive and delicious! Trichome production on the cannabis flowers is truly top-class and combined with her unique terpene profile this ensures she appeals to all types of growers.
Speaking of flavour, she has a sweet, fruity taste with occasional sour and more earthy notes in the background. Some plants really taste like a tropical fruit cocktail, a little sangria-like with the fresh sourness of a grapefruit or blood orange. Wonderful to smoke in a fat joint or in the vape, where the interesting nuances come through particularly well. Auto GrapefruitZ typically combines sweet-sour fruit notes with exceptional freshness, creating a pleasant smoking experience.
Auto GrapefruitZ is a true all-rounder — easy to grow and delivers a large XL yield
Auto GrapefruitZ is a fine quality autoflower seed variety with genetics which make for easy cultivation, even for beginners. She has a vigorous, robust vegetative phase with a controllable medium-sized plant structure. Combined with the high XL yield and high quality, this makes her a popular autoflower strain for all types of growers looking for a strong ‘all-rounder’ without compromises.
What genetics are in Auto GrapefruitZ?
Auto GrapefruitZ is a beautiful addition to our Orange family of cannabis seeds. Besides her fruity citrus-dominant terpene profile she usually also develops beautiful orange pistils that are characteristic of the strains in the Dutch Passion Orange family. The genetics were created by crossing our photoperiod Passion Fruit with Auto Melonade Runtz. These genetic lines provide a wide genetic background for this hybrid autoflower.
Our Passion Fruit (Sweet Pink Grapefruit x Orange Bud) contributes the very fruity character, while Auto Melonade Runtz ((Auto Pink Runtz x Melonade (Lemon Z x Lemon Tree)) brings the high potency and clearly present trichome development.
Together they create a fine hybrid autoflower that leans slightly more towards the Sativa side of the genetics. Her plant and bud structure is also that of a Sativa-dominant hybrid — medium to large, nice full buds, relatively compact but not super fluffy, and usually with beautiful orange pistils. This is an easy and powerful autoflower that will please everyone.
Auto GrapefruitZ produces medium-sized plants with beautiful full flowers that can smell truly deliciously fruity and deliver a large XL yield
Auto GrapefruitZ normally produces larger medium autoflower plants with a very high yield. The buds lean more towards Sativa-looking flowers in appearance, with foxtails and a slightly more open structure in some phenotypes. However, this certainly does not apply to all phenotypes.
Some are considerably more compact and look more like a 50/50 hybrid (50 % Sativa, 50 % Indica). This autoflower cultivar is characterised by unique fruity terpenes; combined with the large XL harvest, these are the reasons you really should grow this strain!
She is relatively fast from seed to harvest. Although we indicate that she needs approximately 12 weeks from autoflower seed to fully mature plant, faster plants can certainly be found that finish closer to 11 weeks. And some even around 10.5 weeks.
All plants display the well-known ‘hybrid vigour’, meaning they grow and flower quickly. Thick, strong branches are also a hallmark of this strain. This ensures the large blooms are well supported when fully grown. Her fine growth pattern also makes her suitable for manipulation or training using various techniques such as LST or HST (topping, FIMming, etc.).
Although there are certainly differences to be found in growth pattern and flowering time, the terpene profiles stay reasonably close to each other — the fruity character is usually dominant. You will also notice that during the final weeks of flowering the plants bulk up considerably and the buds appear to get a bit thicker every few days!
Most plants develop light-green/white buds, but on the leaves, you will find beautiful colourations that usually turn pink, reddish or very light purple. A small percentage of plants can also develop pink/purple tones in the buds, which contributes to the unique appearance and attractive bag appeal.
Trichome production is genuinely excellent and some flowers are completely snowed under! For an autoflower of this size it is certainly impressive. The THC level falls into the ‘Very High’ category and normally ranges between 15–20 %. However, outliers are definitely possible, especially when grown under the right conditions and with great care.
Her plant structure sits between compact and open; in size she is medium to large (depending on the phenotype) and the internode distance is average. This usually results in nice full blooms that can become quite large. The combination of the fruity terpene profile, the beautiful ‘frosty bag appeal’ and solid potency makes her very popular with growers looking for an uncomplicated and relatively fast autoflower harvest.
The genetics used for Auto GrapefruitZ guarantee the following characteristics:
- A relatively fast-flowering Sativa-dominant hybrid autoflower.
- Beautiful full white buds that take on average approximately 11–12 weeks to fully mature from seed to harvest.
- An XL yield of the highest quality; the very fruity terpene profile combined with the great ease of cultivation makes her a popular autoflower cultivar.
- Auto GrapefruitZ is a powerful feminised autoflowering cannabis seed variety with beautiful white buds and attractive light pink/purple colourations on the leaves.
Effects of Auto GrapefruitZ
Auto GrapefruitZ produces beautiful full open buds with a solid sticky resin layer. The connected flowers sometimes look as if they have been completely snowed under.
In terms of potency, she falls into the ‘Very High’ THC category, and if grown well this can even reach ‘Extremely High’, resulting in a powerful yet pleasant effect! The effect is more of a hybrid high, with both mental and physical effects.
She generally leans a little more towards the energetic, uplifting mental effect. Euphoric and uplifting — wonderful to enjoy in the morning or during the day when you still have a full day ahead of you!
Eventually the high transforms into a relaxed feeling of bliss, perfect for winding down and recovering from an intense (work) week. The effect combined with the average THC content of approximately 15–20 % delivers a strong high that never feels overwhelming. You retain control and can therefore dose this strain well and easily.
It is a suitable strain for people who enjoy a medium to strong high that gives you the right drive to take on certain (creative) tasks or work. She creates focus and mental clarity, ideal for people who like to stay active after consuming cannabis. The improved focus for work, sport or energy while gaming makes this a popular autoflower strain among everyday smokers!
Flowering time of Auto GrapefruitZ
Auto GrapefruitZ has an average seed-to-harvest time of approximately 12 weeks. However, due to the phenotype differences present, faster plants can also be found that finish around 10.5–11 weeks.
These are usually the slightly more compact/smaller plants. They stretch a little less, which means they start flowering and finish earlier. These more compact plants often still develop thick blooms. Therefore, allow for an autoflower seed-to-harvest time of between 75–85 days.
Thanks to her hybrid and more open bud structure she is also suitable for outdoor growing and greenhouse cultivation. In an outdoor/greenhouse grow the total cycle can be delayed by 1 to 2 weeks due to periods with little sun or poorer/colder weather. Because of the fuller and more open structure of the buds, this strain handles warm and more humid conditions quite well. In warm and dry areas this autoflower performs truly fantastically — both on a balcony and in the ground. Even in temperate climates she does fine, although it is recommended to choose the most favourable and sunniest summer months for the best results.
Yield of Auto GrapefruitZ
Auto GrapefruitZ is a hybrid autoflower with good bag appeal. All buds have a substantial layer of trichomes and are quite sticky & smelly! Smelly in the good sense of course (‘stinking’ meaning a penetrating and intense aroma), smelling of sour citrus fruit and a tropical fruit cocktail!
The buds become large and after drying have attractive bag appeal. Auto GrapefruitZ produces an XL yield in combination with an average seed-to-harvest time. Indoors this will average between 500–550 g/m². She can be grown on 18/6 as well as 20/4 or even 24/0 light cycles. If you are an expert grower you can achieve between 600–700 g/m².
Outdoors most plants will yield between 30–75 g of dry buds per plant. Of course, the same rule applies here: the more hours of (sun)light and the better the climate, the higher the yield you can obtain. Experienced growers in a favourable climate can get around 100–150 g per plant.
If you grow in a hydro system and apply certain training techniques, you can achieve even higher yields both indoors and outdoors. However, this is mainly reserved for cultivation experts.
Advice from our experts
Auto GrapefruitZ is a medium to large autoflowering cannabis seed variety. A fine addition to the classic citrus-fruit-dominant ‘Orange Family’ from Dutch Passion. This cultivar does not require special feeding schedules or growth techniques to reach a good conclusion. Literally everyone can achieve good yields with her — from beginners to intermediate to expert growers. For the absolute tastiest end-result, we recommend growing her organically. This also makes it easier to give her exactly what she needs.
She also performs well on coco (and with coco nutrients). Want to really maximise yield? Then grow her in a hydro system with powerful LED lights. If you also run her on 24/0 (24 hours light / 0 hours dark per day) throughout the entire cycle, yields can in some cases even reach XXL. However, we only recommend this for experienced experts.
Try to keep her nutrition in the ‘sweet spot’ throughout the grow and she will reward you richly with a very large harvest!
