9 New Fast Buds Strains 2026: Release Guide
Fast Buds has added nine genuine new releases to its catalogue: eight feminised autoflowers and one photoperiod F1 hybrid, Z42. Gorilla Cannabis Seeds has brought the complete group together for UK collectors who want to compare the genetics rather than decode nine separate product pages.
This guide covers the confirmed crosses, breeder-reported THC figures, stated flowering periods and flavour profiles behind the new Fast Buds strains 2026 collection. Every number comes from current official Fast Buds information and should be read as a breeder figure, not a guaranteed outcome.
One correction matters from the start: Z42 is part of this release group, but Fast Buds explicitly identifies it as a photoperiod strain—not an autoflower. The remaining eight are listed as feminised autoflowers. You can compare them with the wider Fast Buds breeder page after seeing what separates this particular drop.
Meet the nine releases

All figures and descriptions above are reported by Fast Buds. Natural expression varies, and the breeder’s figures are not guarantees.
Banana Cherry Cookies Auto
Banana Cherry Cookies Auto crosses Fast Buds’ Lemon Cherry Cookies Auto with Banana Jealousy Auto RF3. Fast Buds calls it an F1 feminised autoflower with a 35% sativa and 65% indica split. The breeder reports THC of up to 30% and an eight-week flowering period.
Its stated profile is ripe banana candy layered with sweet cherry, tropical fruit, citrus and creamy sherbet. That puts it firmly in the dessert-fruit side of this release, but the lineage is what gives collectors more to investigate. Fast Buds describes both parents as decorated genetics: Lemon Cherry Cookies Auto received major 2025 recognition, while Banana Jealousy took an indica award in the autoflower scene.
Compared with the other eight, this is the most direct collision of banana, cherry and cookies cues. It should interest collectors who follow modern champion-line crosses or want one pack tying together two of the dominant themes in the 2026 drop: fruit-forward profiles and award-linked parentage.
Banana Frost Auto
Banana Frost Auto pairs Banana Jealousy RF3 with Frostbanger Auto. Fast Buds lists it as an F1 feminised autoflower, leaning 60% indica, with up to 30% THC and a reported nine-week flowering period.
The official taste markers are citrus, cream, sweetness and tropical fruit. Fast Buds expands that into ripe banana, citrus zest and a subtle gassy undertone. Those are breeder descriptions rather than a promise that every expression will present the same balance.
The useful distinction is the Frostbanger side. Banana Cherry Cookies combines banana with cherry-cookie genetics; Banana Guava doubles down on tropical fruit; Banana Frost instead connects Banana Jealousy to a resin-associated Fast Buds line with a light gas edge. That makes it the most obvious choice for an adult collector specifically comparing Fast Buds’ “Frost” crosses while still wanting banana-led heritage and a high breeder-reported cannabinoid figure.
Banana Guava Auto
Banana Guava Auto is Guava Auto RF3 crossed with Banana Jealousy RF3. According to Fast Buds, it is an F1 feminised autoflower with a 65% indica lean, a reported 9–10-week flowering period and THC up to 28%.
The breeder lists banana, cream, fruit and guava as its main taste markers. Its own description puts particular weight on the terpene profile rather than trying to make potency the whole story. That is a useful difference in a group where several releases carry higher headline THC figures.
Fast Buds places this strain in its Champions Line and says both parents won categories at the same Autoflower World Cup: Guava Auto RF3 for sativa and Banana Jealousy for indica. For collectors, that opposing award heritage is more meaningful than simply reading “banana” and “guava” in the name. This is the release for someone interested in a tropical cross built from two RF3-associated parent lines and a clearly documented competition connection.
GMO Auto
GMO Auto breaks sharply from the fruit bowl. The confirmed cross is GMO Cut × Chemdog Auto, and Fast Buds identifies it as an F4 feminised autoflower with an 80% indica lean. The breeder reports up to 28% THC and a 10–11-week flowering period—the longest stated window in this group.
Its official profile is earthy, garlic, herbal and spicy. That savoury direction makes GMO Auto the clearest outlier among releases dominated by banana, mango, cherry, pineapple, cream and candy descriptions. No guesswork is needed here: the breeder’s own data places it in a different flavour family.
The F4 label is also worth noting. In simple terms, F4 indicates a later filial generation than the many F1 hybrids in this launch; it does not automatically make a strain better, but it describes a different stage in the breeding line. GMO Auto should appeal to collectors who favour Chem-related ancestry, savoury profiles or later-generation autoflower projects over sweet dessert crosses.
Mango Cherry Runtz Auto
Mango Cherry Runtz Auto combines Mango Runtz F5 Auto with Lemon Cherry Cookies Auto. Fast Buds lists an eight-week flowering period and THC up to 28.5%, with a 65% indica lean. Its product introduction calls it an F1 feminised hybrid autoflower, while the technical table shortens that to F1 hybrid autoflower.
The breeder describes tropical mango, sweet cherry, sour citrus and creamy cookie notes; its concise taste markers are cherry, fruit, mango and spice. The cross therefore joins fruit and dessert themes without simply repeating Banana Cherry Cookies.
Fast Buds says Mango Runtz F5 Auto won Best New Autoflower at the 2025 Autoflower World Cup, while Lemon Cherry Cookies Auto collected recognition at the American Autoflower Cup and Grow Awards. That documented pairing is the distinguishing feature. Collectors following competition-linked autoflower families may see this as the most direct record of two different 2025 champion lines meeting in one release.
Mango Frost Auto
Mango Frost Auto crosses Mango Runtz Auto with Frostbanger Auto. Fast Buds describes it as an F1 feminised autoflower with a 65% sativa lean, up to 30% THC and an eight-week flowering period.
Its official taste listing is cream, sweet and tropical. The longer breeder description adds ripe mango, a slightly sour edge and gas beneath the creamy finish. Within this launch, Mango Frost and Banana Frost make a clean comparison: both use Frostbanger Auto, but one takes a sativa-leaning mango direction while the other is an indica-leaning Banana Jealousy cross.
That structure makes Mango Frost particularly relevant to collectors who compare related breeding branches rather than buying on strain names alone. It also combines one of the shortest stated flowering periods in the group with one of the joint-highest autoflower THC claims. Those remain Fast Buds figures, not promised results, but they clearly explain how the breeder is positioning the release.
Mendo Cherry Cookies Auto
Mendo Cherry Cookies Auto is listed as Lemon Cherry Cookies Auto × Mendo Breath. Fast Buds further explains that the project uses Mendo Breath Auto IBL from Atlas Seed, a line involving GMO Auto and Mendo Auto. The finished release is described as an F1 feminised autoflower with a 70% indica lean.
Fast Buds reports up to 30% THC and an eight-week flowering period. Its stated profile combines cherry, citrus, cream, sweetness and vanilla, with the fuller description adding vanilla candy, soft caramel and light spice.
This is the deeper dessert entry in the set. Banana Cherry Cookies leans into banana and tropical fruit; Mango Cherry Runtz brings mango and Runtz heritage; Mendo Cherry Cookies puts creamy vanilla and caramel around the Lemon Cherry Cookies parent. It should suit collectors interested in breeder collaborations, IBL-linked ancestry or a cookie profile with a more savoury Mendo/GMO family sitting behind it.
Pineapple OG Auto
Pineapple OG Auto combines Pineapple Express with OG Kush Auto. Fast Buds labels it an F4 feminised autoflower, 65% sativa and 35% indica, with up to 30% THC and a reported nine-week flowering period.
The flavour information is unusually focused: sour pineapple, sweetness and tropical fruit. The OG Kush Auto side provides a familiar counterpoint to Pineapple Express ancestry, making this less of a multi-dessert hybrid and more of a clear two-family combination.
Fast Buds also gives Pineapple OG Auto an XXL size classification and reports a broader height range than the other new autos. Those are descriptive breeder specifications, not a performance promise, but they distinguish the listing on paper. For collectors, the appeal is straightforward: recognisable Pineapple Express and OG Kush-associated genetics, an F4 designation, a sativa lean and a profile that stays centred on sour tropical pineapple rather than cookies or cream.
Z42
Z42 is the exception that stops this being a nine-autoflower article. Fast Buds states explicitly that it is a full photoperiod release and says no auto version is planned. Its confirmed lineage is Z3 from Terphogz × Candy Fumez from Bloom Seed Co., produced as a limited-edition F1 feminised hybrid.
The breeder reports up to 31% THC, the highest stated figure in this release group, and an 8–9-week flowering period. Candy, cream and fuel are the official taste markers, expanded by Fast Buds into Z-style candy, tropical fruit, sherbet and sweet fuel.
Z42 is also the only 50/50 sativa-indica entry and is listed considerably taller than the eight autos. Its interest lies in original named breeder material and the move beyond Fast Buds’ best-known autoflower territory. Collectors wanting every genuine release in the drop will need it; anyone wanting autos only should leave Z42 out of that comparison.
How do the nine new Fast Buds strains compare?
Fruit-led profiles
Banana Guava Auto is the clearest tropical pairing, while Pineapple OG Auto stays focused on sour pineapple. Mango Frost Auto and Mango Cherry Runtz Auto carry mango-led breeder descriptions, with the latter adding cherry, citrus and cookie notes. Banana Cherry Cookies Auto also spans several fruit markers rather than sticking to banana alone.
Dessert and cookie-influenced genetics
Banana Cherry Cookies Auto, Mango Cherry Runtz Auto and Mendo Cherry Cookies Auto all use Lemon Cherry Cookies Auto as a parent. Their second parents take that shared base in different directions: banana candy, mango-Runtz fruit or Mendo-linked vanilla and caramel. Banana Frost and Mango Frost add creamier profiles without using the Cookies parent.
Savoury, gas and fuel
GMO Auto is the obvious savoury option, with garlic, earth, herbs and spice reported by Fast Buds. Z42 occupies candy-gas territory, while Banana Frost and Mango Frost include gas in their fuller breeder descriptions. They should not be treated as interchangeable: GMO’s official profile is far removed from Z42’s candy and cream.
Shortest breeder-reported periods
Banana Cherry Cookies Auto, Mango Cherry Runtz Auto, Mango Frost Auto and Mendo Cherry Cookies Auto are all listed at eight weeks. Z42 is stated at 8–9 weeks, but it is photoperiod, so that figure is not directly equivalent to an autoflower life-cycle claim. GMO Auto has the longest stated period at 10–11 weeks.
Strongest breeder-reported THC figures
Z42 leads on paper at up to 31%, followed by Banana Cherry Cookies Auto, Banana Frost Auto, Mango Frost Auto, Mendo Cherry Cookies Auto and Pineapple OG Auto at up to 30%. Mango Cherry Runtz Auto is listed at up to 28.5%; Banana Guava Auto and GMO Auto at up to 28%.
These are breeder-reported upper figures. Cannabinoid content, aroma, colour and other expressions can vary, so the numbers are comparison points rather than guarantees.
Which new Fast Buds release should collectors consider?
| Collector interest | Releases to compare | Why |
|---|---|---|
| Tropical fruit | Banana Guava Auto, Mango Frost Auto, Pineapple OG Auto | Guava-banana, mango-cream and sour-pineapple directions |
| Cherry-cookie heritage | Banana Cherry Cookies Auto, Mango Cherry Runtz Auto, Mendo Cherry Cookies Auto | All share Lemon Cherry Cookies Auto parentage |
| Savoury Chem ancestry | GMO Auto | GMO Cut × Chemdog Auto; garlic, earth, herb and spice listing |
| Frostbanger branches | Banana Frost Auto, Mango Frost Auto | Same Frostbanger parent, different fruit parent and genetic lean |
| Highest stated THC | Z42 | Fast Buds reports up to 31%; it is photoperiod, not auto |
| Eight-week auto listing | Banana Cherry Cookies, Mango Cherry Runtz, Mango Frost, Mendo Cherry Cookies | Shortest stated flowering period among the eight autos |
| F4 autoflower projects | GMO Auto, Pineapple OG Auto | Later-generation designation rather than F1 |
There is no universal winner here. The useful choice depends on whether the collection is organised around lineage, release format, breeder generation, flavour family or stated specifications.
Fast Buds and modern autoflowering genetics
Fast Buds—also known as 42 Fast Buds—is an international cannabis seed breeder best known for autoflowering genetics, although its catalogue now includes photoperiod releases as well. That second point matters because Z42 demonstrates the broader direction of the brand.
A coordinated release of eight new autos is notable because the lines are not nine random names. Several create visible branches around Lemon Cherry Cookies Auto, Banana Jealousy RF3, Mango Runtz and Frostbanger Auto. That gives collectors meaningful related crosses to compare.
The group also covers F1 and F4 releases, indica- and sativa-leaning genetics, fruit, dessert, savoury and fuel profiles, plus breeder-reported figures from 28% to 30% across the autos. The complete Fast Buds seed collection lets collectors compare this drop with established lines and earlier RF3 releases.
