Zours Rosin & Bubble Hash Yield Dossier: WPFF Wash %, Micron Sieve & Press Temp
Zours (Zkittlez x Sour Diesel) is a verified A-Tier Washer (4.5%-6%) solventless cultivar averaging 4.5% - 5.5% wet Whole Plant Fresh Frozen (WPFF) ice-water bubble hash yield, 76% - 82% hash-to-rosin press return (~3.95% net WPFF-to-live-rosin return), and 22% - 26% direct cured flower rosin return. Its prime trichome head collection window is 73u - 119u, pressed at 148F - 158F in a 25u double-bag to produce Sour Candy-Fuel Cold-Cure Badder dominated by Limonene, Beta-Caryophyllene, Myrcene.
Zours
Rated A-Tier Washer (4.5%-6%). Expect ~3.95% net live rosin from fresh-frozen weight or 24.0g per 100g of cured buds.
Press hash in a 25u + 160u double-bag at 350-500 Bag PSI; press flower in a 90u Bottle-Tech bag at 750-950 Bag PSI.
Dominant terpenes: Limonene, Beta-Caryophyllene, Myrcene. Keep freeze-dryer shelves at 40F-45F to protect volatile top notes.

Because Zours (Zkittlez x Sour Diesel) expresses a dominant Limonene, Beta-Caryophyllene, Myrcene terpene profile and collects heavily in the 73u - 119u sieve bags, maintain wash water at 32F-34F with minimal shear vortex during the first two 6-minute washes. Lyophilize at a 40F-45F shelf temperature limit, press at 148F - 158F, and whip after 72 hours at 64F to lock in a glossy Sour Candy-Fuel Cold-Cure Badder consistency.
