Where Double Stack Comes From
Double Stack comes from Compound Genetics, the breeder behind Pave and Jet Fuel Gelato. SeedFinder, Zamnesia and other seed shops list the cross as Apple Fritter x Jet Fuel Gelato, and GrowDiaries also credits Compound Genetics as the creator. SeedFinder traces Apple Fritter to Sour Apple and Animal Cookies, and Jet Fuel Gelato to Jet Fuel and Gelato.
The name fits the breeding goal. Both parents are known as heavy producers, and the seed descriptions stress that Double Stack inherits that output, along with the creamy dessert flavor of Apple Fritter and the resin of Jet Fuel Gelato. It is sold only as feminized seed.
Because it is newer and mostly a seed release, Double Stack has less consumer review data than older strains. Leafly does not yet have a full strain page for it, so most of what is known comes from the breeder’s descriptions and grow reports.
Double Stack Effects: What It Feels Like
SeedFinder describes a short burst of euphoria that leads into a sense of physical and mental well-being, and Zamnesia lists the effects as euphoric and relaxing, with the head high eventually giving way to a soothing body feel. Grower reviews summarized online describe the same arc: a fast, happy onset that turns calmer as it goes.
That shape makes it a reasonable pick for late afternoon or evening, when a lift in mood is welcome but a slow finish is fine. Listings put THC in the mid to high 20s, so newer consumers should start small and give it time before deciding whether they want more.
Double Stack Terpenes, Aroma and Flavor
Seed listings describe Double Stack as sweet, fruity and smooth, with spice and an ice-cream-like creaminess underneath. That lines up with its parents: Apple Fritter brings the sweet, creamy pastry side, and Jet Fuel Gelato adds a sharper, spicier edge.
Zamnesia lists ocimene and caryophyllene as the notable terpenes. Ocimene is often linked with sweet, fruity and herbal notes, and caryophyllene with pepper and spice, which fits the fruit-then-spice description.
- Ocimene: sweet, herbal and woody, also found in mint and basil
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
Side Effects and How to Use Double Stack
There is little published review data on side effects for Double Stack. As with most potent hybrids, dry mouth and dry eyes are the usual complaints, and a large dose of a strain in the mid 20s for THC can feel heavy or leave newer consumers anxious. Start low.
If you are new to Double Stack, start with one small inhalation or 2.5 mg in an edible and wait before taking more; see our dosing guide.
Growing Double Stack
- Difficulty: Easy
- Flowering: About 58–63 days (7–8 weeks); some phenotypes run closer to 10 weeks
- Yield: Very high; Zamnesia cites roughly 450–600 g/m² under ideal conditions
- Environment: Indoor, outdoor or greenhouse; outdoor harvest in September or October
SeedFinder lists indoor flowering at 58 to 63 days, about 60 on average, with some phenotypes taking closer to 10 weeks, and an outdoor harvest in September or October. Both SeedFinder and Zamnesia stress very high yields, with Zamnesia quoting up to about 600 g per square meter under ideal conditions and rating it easy to grow. Heavy, stacked colas need support and good airflow, especially for outdoor plants finishing into a wet autumn.
Home-grow rules depend on the state: adults can grow at home in states such as California (six plants per residence), Michigan (12 per residence) and Oregon (four per household), while Washington and Illinois allow home growing only for registered medical patients. Check your state in our cannabis laws by state guide before you plant anything.
