Gorilla Sift

Rosin · 5-Star

GG4 derivative bred specifically for rosin pressing. Dense, oily trichomes that return exceptional rosin yields at 190°F. Not the highest wash yield — but the press output is ridiculous.

Reading the wash data

Questions extractors actually ask

WASHHOUSE breeds cannabis seeds for one job: performance under extraction. Every cut in the catalog is selected from a pheno hunt of 800–4,800 plants (27,600 screened across the catalog) and published with its wash yield, micron band, melt rating and press return. Here is what those numbers mean and how to pick with them.

What is wash yield, and what counts as a good one?

Wash yield is the share of dry flower weight that comes back as ice-water (bubble) hash after a wash. WASHHOUSE publishes a figure for every cut, measured on our own runs during the pheno hunt. Across the 14 cuts in this catalog the published range is 3.2% to 5.9%. As a rule of thumb, roughly 4% and up is a strong washer and 5%+ is exceptional — most commercial flower is nowhere near that, because it was bred to be smoked, not washed. The highest published yields here are Colombian Gold Washer (5.9%), Medellín Melt (5.6%), Triple M OG (5.2%). These are breeder observations from our runs, not a guarantee: freshness, harvest timing, water temperature, agitation and drying technique all move the number.

What does micron mean, and which bag should I pull from?

A micron (μ) rating is the mesh size of a filter bag, which sorts trichome heads by diameter. Mature heads mostly land between about 45μ and 120μ; the 73–90μ window usually holds the cleanest, meltiest fraction, while bags above about 120μ catch larger heads along with more plant material, and bags below 45μ catch immature heads and contaminants. Every WASHHOUSE cut publishes the band its heads concentrate in, so you can stack your bag set around the genetics instead of guessing. Bands in this catalog: 73-90μ, 73-120μ, 90-120μ, 73μ, 90-150μ.

What is full melt, and what does a 6-star melt rating mean?

Melt describes how completely hash liquefies and bubbles under heat instead of leaving charred residue. It is graded on a 6-point star scale: 1–3 star is press/edible-grade material, 4 star melts partially, and 5–6 star ("full melt") melts cleanly enough to dab on its own. WASHHOUSE grades every cut on that scale. In this catalog: 6 cuts at 6-Star, 6 at 5-Star, 2 at 4-Star. The 6-Star cuts are Triple M OG, Medellín Melt, Colombian Gold Washer, Press Club Kush, Full Melt Haze, Chem Dump. Melt is a property of the resin the genetics produce and how it is washed and dried — the rating describes what these seeds are bred to produce, not a promise about any given run.

Which cut should I buy for ice-water (bubble) hash?

Sort on ice-water affinity first, then on published wash yield and micron band. Cuts bred for the wash have large, brittle-stalked trichome heads that detach cleanly under cold agitation. The strongest ice-water performers in this catalog:

  • Medellín Melt — 9.8/10 affinity, 5.6% wash, 73-90μ, 6-Star melt.
  • Colombian Gold Washer — 9.7/10 affinity, 5.9% wash, 73μ, 6-Star melt.
  • Triple M OG — 9.5/10 affinity, 5.2% wash, 73-90μ, 6-Star melt.
  • Full Melt Haze — 9.3/10 affinity, 4.9% wash, 73-90μ, 6-Star melt.
Which cut should I buy for dry sift?

Dry sift rewards different traits than ice water: long, fragile trichome stalks that snap on a screen, dense resin coverage on sugar leaf, and a plant structure that dries evenly. Landrace-derived hash genetics dominate here. The strongest dry-sift performers in this catalog:

  • Rif Mountain #3 — 9.8/10 affinity, 4.5% wash, 90-150μ, 4-Star melt (currently out of stock).
  • Moroccan Temple #7 — 9.6/10 affinity, 4.8% wash, 73-120μ, 5-Star melt.
  • Black Afghan Sift — 9.4/10 affinity, 5% wash, 90-150μ, 5-Star melt.
Which cut should I press for rosin, and what is a good press return?

Press return is the share of input weight that comes back as rosin. Published returns in this catalog run 16% to 31%, with the highest being Press Club Kush (31%), Papaya Press (29%), Gorilla Sift (28%). Compare cuts to each other rather than to a number you saw elsewhere: returns depend enormously on what you load — hash rosin returns far more than flower rosin — plus press temperature, pressure and bag micron. The strongest rosin performers by affinity score:

  • Press Club Kush — 9.8/10 affinity, 4.4% wash, 73-90μ, 6-Star melt.
  • Gorilla Sift — 9.4/10 affinity, 4.1% wash, 90-120μ, 5-Star melt.
  • Papaya Press — 9.3/10 affinity, 4% wash, 73-90μ, 5-Star melt.
Which cut is best for hydrocarbon extraction (BHO, live resin)?

Hydrocarbon rewards terpene retention and total resin content more than head size or stalk fragility, so the ranking looks different from the wash. The strongest hydrocarbon performers in this catalog:

  • Solvent Trap — 9.6/10 affinity, 3.2% wash, 90-120μ, 4-Star melt.
  • Chem Dump — 9.5/10 affinity, 4.7% wash, 73-120μ, 6-Star melt.
  • Gorilla Sift — 8.8/10 affinity, 4.1% wash, 90-120μ, 5-Star melt.
How long do these take to flower?

Published flowering windows in this catalog run from 50-55d (Black Afghan Sift, the fastest) to 75-85d (Rif Mountain #3, the longest). Most cuts sit in the 58–68 day band. Landrace-derived hash lines — Moroccan and Rif genetics in particular — run longer and taller; indica-leaning and modern hybrid cuts finish faster. Flowering time is listed on every product page alongside height, so you can match a cut to your cycle length before you match it to a wash number.

What is the difference between the feminized and regular cuts?

Feminized seeds are bred to produce only female (resin-producing) plants, which is what most extractors want — you plant what you intend to harvest. Regular seeds produce both males and females, which is what a breeder or pheno hunter wants, because you need males to make pollen and to run your own selections. This catalog carries 11 feminized cuts and 3 regular cuts (Moroccan Temple #7, Rif Mountain #3, Black Afghan Sift). Genetics type is listed on every product page.

What does "plants screened" mean on a product page?

It is the size of the pheno hunt behind the cut: how many individual plants were grown out and evaluated before that phenotype was selected and stabilised. In this catalog the number runs from 800 to 4,800 plants per cut, 27,600 plants in total. A bigger hunt means harder selection pressure — it is a measure of how much work went into the selection, not an automatic quality score, and it is published so you can judge the claim rather than take it on faith.

Do the published numbers guarantee I will get the same result?

No. Every figure on this site — wash yield, micron band, melt rating, press return, flowering time — is a breeder observation recorded on our own runs, under our own conditions, and describes what the genetics are bred to produce. It is not a guarantee of your result and is not offered as one. Your outcome depends on environment, nutrition, harvest timing, how fresh or how well dried the material is, your water temperature and agitation, your bag set, your press, and your technique. WASHHOUSE makes no medical, therapeutic, or potency claims of any kind.

What am I actually buying, and is it legal?

You are buying cannabis seeds sold as adult (21+) collector / novelty items by Breedtech LLC, a US company. They are sold as collectibles and souvenirs — not sold for germination where germination is prohibited, and it is the buyer's responsibility to know and follow the law where they live. Age verification (21+) is required to enter the store. Nothing on this site is medical advice and no therapeutic or potency claim is made or implied.

What pack sizes and prices are available?

Packs come in 3, 6, 12 seeds depending on the cut, priced from $40 for an entry pack (Black Afghan Sift) up to $260 for the largest pack of the most sought-after cut. Limited and seasonal releases are often offered in a single pack size only, and once a run is gone it is gone until the line is grown again. Prices are in USD and every pack size and price is listed on the product page.

All performance figures are breeder observations recorded on WASHHOUSE runs and describe what the genetics are bred to produce. They are not a guarantee of any result. No medical, therapeutic, or potency claims are made. Seeds are sold by Breedtech LLC as adult (21+) collector / novelty items and are not sold for germination where prohibited by law.
