About Grape OX Feminized
We have run Grape OX across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this indica delivers a myrcene-forward flower at 22% THC that matches the genetic promise. The 71/29 profile shows in how the plant structures itself β bushy, compact, eager to fill lateral space. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.
What We Observed Growing This Strain
The vegetative phase was unremarkable in the best possible way β steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was minimal β maybe 25-30% height increase.
Flowering completed in 9-11 weeks. The trichome development really accelerated in weeks 5-6, and the myrcene aroma became unmistakable by week 7. Final indoor yield: 400-500g/mΒ² under LED. Height at harvest: Compact (2-3 ft). Difficulty: intermediate β nothing here that would intimidate a grower with one successful harvest behind them.
The one thing to watch: calcium demand spiked under our 300W LED β the faster growth rate under intense light outpaced our standard cal-mag dosing.
Effects and Use
At 22% THC, Grape OX delivers euphoric, calm effects with a myrcene-influenced character. The onset is body-first β a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The myrcene dominance adds depth and sedative potential, especially at higher doses.
Terpene Profile
Dominant terpenes: Myrcene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385Β°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.
Who Should Grow Grape OX
Best suited for growers who want control over their plant size and harvest timing β photoperiod genetics let you veg as long as you want before triggering flower. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
