The Cross
Buy Grape Diamonds R2 seeds if you want Ethos Genetics' refined take on Memberberry. They crossed Grape Diamonds phenotype with Pink Grapefruit phenotype, both from Memberberry, to build R2. Goal was terpene complexity and structural reliability. Grape skunk base, tart grapefruit lift, propane edge. Breeder hit the marks: flavor stacks, plants branch hard, yields stack without drama.
No one-hit wonder here. Ethos knows Memberberry inside out. This refines it.
What Each Parent Brings
Grape Diamonds delivers the skunk core. Dense grape terps, resin heads that frost nugs solid. Structure holds under weight, laterals spread wide. Yields medium to high with minimal stretch.
Pink Grapefruit adds the citrus bite. Tart edge cuts the sweetness, boosts terp volatility. Faster finish, more vigor in veg. Hardiness against stress, powdery mildew especially.
Together, R2 stabilizes both. Confirmed: 25-30% THC, balanced hybrid vigor.
The Phenotypes
Three main types show in packs. Grape dominant: skunk heavy, purple hues late flower, compact node stack. Tart balance in 20 percent.
Grapefruit lean: pink buds, citrus forward, looser structure but faster finish. Yields dip five percent, terps pop harder. Best for flavor chasers.
Balanced keeper: 60 percent of run. Even terps, strong laterals, uniform height. Run this one. Cut stretchy grapefruit if space tight.
Variation low for R2. Phenotype stability is the sell.
Finding the Keeper
- Seedling: Even cotyledons, quick root. Weak hooks out early.
- Veg: Lateral branching by week three. No foxtail tops. Smell hits: propane first, grape builds.
- Flower week three: Resin beads form. Nodes tighten. Stretch under 100 percent.
- Late flower: Hard nugs, no foxing. Aroma shifts tart. Test THC if you can; 27 percent average.
Trichs milky at 60 days. Hunt the balanced pheno by aroma and structure week four flower.
In the Garden
Flower time locks 60-63 days. Veg eight to 10 weeks for bush. Indoors, 18-24 inches final height. Outdoors, harvest October, yields two pounds per plant in good sun. Hardy against heat, bugs. Beginners get it right first run. Data confirmed from Ethos notes.
The Experience
Balanced hybrid snap: clear head first, body melt follows. Grape skunk lingers on exhale, grapefruit cleans the finish. Potent at 25-30% TAC. Solid for day into evening. No couch-lock hype.
