Subzero Rosin & Bubble Hash Yield Dossier: WPFF Wash %, Micron Sieve & Press Temp
Subzero (Oreoz x Super Boof) is a verified S-Tier Dumper (6%+) solventless cultivar averaging 5.0% - 6.1% wet Whole Plant Fresh Frozen (WPFF) ice-water bubble hash yield, 74% - 81% hash-to-rosin press return (~4.30% 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 150F - 162F in a 25u double-bag to produce Frosty White Badder dominated by Caryophyllene, Limonene, Myrcene.
Subzero
Rated S-Tier Dumper (6%+). Expect ~4.30% 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: Caryophyllene, Limonene, Myrcene. Keep freeze-dryer shelves at 40F-45F to protect volatile top notes.

Because Subzero (Oreoz x Super Boof) expresses a dominant Caryophyllene, Limonene, 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 150F - 162F, and whip after 72 hours at 64F to lock in a glossy Frosty White Badder consistency.
