Rate my upcoming WPFF Scrog Grow to Cold Cure / Piattella Hash setup! Strain advice & process optimization needed.
Hey everyone! In my next grow, I’ll be running 4 plants aimed strictly at WPFF (Whole Plant Fresh Frozen) washing for cold cure / Piattella-style hash (no pressing to rosin). I’m planning to harvest around February 2027 and wash outdoors at temperatures around 0°C (32°F).
I’d love your feedback on my setup, workflow, strain choices, and any specific tips for growing or washing these genetics!
Tent & Hardware Setup
Tent: 80x80 cm (approx. 2.5x2.5 ft)
Main Light: SANlight EVO 4-80
UV Light: 2x Luxelite UV (gradually ramped up during Veg to a max of 2 hrs at "noon" through the end of the grow)
Under-Canopy Lighting: AC Infinity IONBEAM S16 (42W)
Airflow & Climate: 2x AC Infinity circulation fans, exhaust system, humidifier, all managed by Controller 69
Medium, Nutrients & Plant Management
Plants: 4 plants total (2x topped/fimmed each + Scrog net)
Medium: Canna Terra Plus & Canna Starter Soil
Watering: Tap water (Cal/Mag baseline: 78 mg/l Cal / 21 mg/l Mag)
Nutrients:
Canna Bio line: Rhizotonic, CalMag, Vega, Booster, Flores Plus
Additives: Alfaboost (throughout the entire grow), Green Bull (Veg only)
Flower Weeks 4 & 5: Epsom salt / Bittersalz (1.5g / 10L) every 2nd watering + PK 13/14 (5ml / 10L) every 3rd watering. No PK or Epsom salt after Week 5.
Harvest Window: When 90%+ trichomes are milky with isolated amber heads.
Strains Chosen
Maple Fumez – Bloom Seeds
Honey Bear – Humboldt Seed Company (HSC)
Papaya Frosting – Barney's Farm
Fresca Pink – Karma Genetics
Washing & Processing Workflow
Equipment: RO System, Graveda washing machine, Deep freezer, BubbleBagDude working bag & mesh screens (160µ, 120µ, 90µ, 73µ, 45µ).
Pre-Wash Prep: RO water chilled to ~0°C (32°F). Machine layering: Ice, Filled 220µ working bag (~550g WPFF), Ice, 20L RO Water. Soak for 10 minutes.
Wash Cycles:
1st & 2nd Wash: 3-5 minutes
3rd Wash to end: 10 to 15 minutes
Drying Process: Vac Tech, Freezer, Microplane, Freezer, Daily sifting until the fire test produces a smooth melt with zero sizzle/brizzel.
Curing (Piattella Style)
Packing: A custom CNC-milled steel press mold (5x10 cm) lined with Piattella Foil (by Uncles). Fill with dry trichome heads, wrap foil, and apply light pressure to form a uniform brick.
Curing: Double Vacuum seal the brick and cure in the fridge at 6–8°C (43–46°F) in complete darkness for 3 to 6 months. No opening or disturbing for at least the first 3 months.
My Questions for You Guys:
Piattella Wrapping Tip: Any specific tricks to avoid wrinkles in the Piattella foil when lining the mold/wrapping the brick?
Workflow & Optimization: What can I improve? Did I forget anything crucial in the washing/drying/curing steps?
Strain Feedback: How is the strain selection for hash/WPFF? Are there any specific quirks or tips regarding growing or washing these exact strains (Maple Fumez, Honey Bear, Papaya Frosting, Fresca Pink)?
Thanks in advance for the knowledge!
Pictures just for eyecatching from one if my latest washes.

EDIT: What do you think? Should i use a scrog net or just topping/fimming and lst?
