Double Up pairs Mellowz with Gastro Pop to deliver dense, resin-rich flowers and a grape-forward, sweet-fuel profile. This indica-leaning hybrid grows with moderate stretch and excellent bag appeal. Ideal for intermediate growers who value terpene intensity and reliable structure.
This Feminized release finishes in 8 to 10 weeks and expresses bold berry, grape, and fuel notes. It suits indoor scroggers, outdoor gardeners in mild climates, and extract-minded growers seeking sticky, uniform resin.
Double Up stands out for its fruit-meets-fuel nose, heavy trichome coverage, and consistent, medium-height structure. Plants show sturdy branching with dense, rounded colas that color up under cool nights, often pushing lavender to deep purple hues. Aromas lean grape and sweet berry with a clean gas backdrop. The cultivar responds well to topping and light defoliation, keeping canopies even and manageable. It performs reliably for indoor tents and controlled greenhouses, with outdoor success in temperate, low-humidity regions. Expect a steady phenotype range centered on the same terpene lane, making selection straightforward for both flower and extraction work.

Mellowz contributes candy-sweet, fruit-forward terpenes and eye-catching color potential, along with a compact frame that is easy to shape. Gastro Pop adds the gassy backbone, thicker calyces, and a resin texture that washes well. Together they create a balanced, indica-leaning hybrid with modern purple hues, dense flower formation, and strong, cohesive aromatics.
Compound Genetics selected this pairing to bring together grape-berry candy with clean fuel while maintaining vigor and stability. Plants show confident lateral branching and a predictable 1.5x stretch, simplifying canopy control. Trichome density is notable across phenotypes, with heads that hold up for both hydrocarbon and solventless work. The cross stays consistent in aroma and structure, making selection efficient for production runs.
On the palate, fruit lands first, followed by a smooth fuel finish. The profile is clean, bold, and persistent, which makes it appealing in flower and concentrates. Growers appreciate how the scent carries through cure, while consumers enjoy the balanced sweet-to-gas progression.
Plants reach medium height with a controlled stretch and strong laterals. Buds are rounded, tightly stacked, and heavily frosted. Colors can shift from lime to deep purple, especially with cooler nights. Resin output is high, and aroma intensity increases through late bloom and cure.
Expect high yields of dense, resin-coated buds with strong grape-berry-fuel terpenes. The cultivar suits intermediate growers comfortable with canopy management and airflow. Buds finish firm and cure well, holding aroma and color when dried with care.
“Intermediate indoor grower here. Two plants in a 3x3 SCROG finished at nine weeks. Great structure, easy trimming, and a loud grape-gas nose. Jar aroma stayed true. Pulled a generous harvest with consistent density across tops and mids.”
“Outdoor, coastal foothills. Kept it staked and thinned and it handled late September well. Fruity first, then a clean fuel finish. Color came in as nights cooled. Washes produced bright, flavorful rosin with a smooth melt.”
Secure Feminized seeds of a grape-forward, fuel-backed indica-leaner with dense buds and strong resin. Expect 8–10 week finishes, high yields, and consistent structure. If you value terpene-rich flowers and efficient canopies, place your order and start your next run.
It’s best for intermediate growers. The plant is manageable, but dense buds require consistent airflow and humidity control. Beginners can succeed with attention to pruning and environment. A simple SCROG or light staking helps keep colas upright and improves light coverage.
Expect 8 to 10 weeks indoors. Most phenotypes finish near week nine with optimal aroma and resin. Always verify readiness with trichome checks and whole-plant maturity, not just calendar days, to hit your preferred ripeness window.
Medium height with about a 1.5x stretch after flip. Training keeps canopies even, making it well-suited to tents and modest ceiling heights. Side branches fill in quickly, so plan for lateral support or netting during mid to late flower.
Pronounced. Grape, berry, and fuel are evident from mid bloom through cure. Use carbon filtration and good airflow indoors. Proper drying and curing will hold the profile without overwhelming grassy notes, preserving clarity in the final jar.
High yields under competent care. Dense colas stack well in SCROG or trellised rooms. Balanced nutrition, steady EC, and strong airflow will help maintain size and prevent microclimates that can limit finish on inner sites.
Yes, aroma and structure stay within a tight range. You may see one candy-grape dominant expression and another with a bit more fuel and stretch. Both remain uniform enough for production, simplifying clone selection for future runs.
Yes. Feminized seeds reduce the chance of male plants, streamlining selection and canopy planning. You should still monitor for rare intersex traits under stress, as with any cultivar, and keep environmental swings to a minimum.
Performs very well indoors and in controlled greenhouses. Outdoors, it prefers temperate, lower-humidity conditions. Provide staking and airflow in regions with cool nights, which can also encourage color without sacrificing flower integrity.
Topping once or twice with SCROG nets creates an even surface of tops. Light defoliation before and during early flower improves airflow. Avoid aggressive late stripping; preserve enough leaf mass to drive flower development through week six and beyond.
Yes. Resin coverage is high, and trichome heads hold up well. The grape-berry-fuel profile translates cleanly into both solventless and hydrocarbon extracts, offering a clear flavor line and strong nose through proper wash, dry, and cure.
