Seeds sold as collectibles only.
Guides, deep-dives, and breeder insights to help you make the best decisions — whether you're buying your first pack or running a commercial facility.
Everything a first-time buyer needs to know: seed types explained, what pack sizes mean, how to read genetics information, what to look for in a legitimate breeder, and how to store your seeds properly on arrival. No jargon, no assumptions — just clear practical guidance.
The three main seed types each serve different purposes. Feminized seeds produce only female plants, making them ideal for most growers. Regular seeds include both males and females, essential for breeders. Autoflowers flower based on age rather than light cycle. This guide explains the trade-offs so you can choose confidently.
Proper seed storage extends germination viability by years. Learn temperature, humidity, and light conditions that preserve genetic quality from the moment your order arrives.
Temperature: Store seeds at 5–10°C (refrigerator) for long-term storage. Stable temperature is more important than the specific number.
Humidity: Aim for 20–30% relative humidity. Use a desiccant packet inside the sealed container.
Light: Keep seeds in a dark, opaque container. UV light degrades the seed hull over time.
Container: Glass is ideal — airtight, no off-gassing. Seal with tape and label with date and strain name.
Running a pack isn't just about growing them out — it's about documenting, evaluating, and selecting the standout phenotype that becomes your signature cut. Here's the system Mile High Dave uses.
Document everything: Track each pheno with photos, smell notes, structure observations, and numerical ratings from day 1.
Run multiples: A 3-pack gives you 3 phenos. A 6-pack or 12-pack gives you real selection range. More seeds = more chances to find the special one.
Evaluate late: Don't cut phenos until at least week 6 of flower. Some of the best expressions don't show until late.
Vapour Pressure Deficit is the single most impactful environmental variable most growers overlook. Getting VPD right can dramatically improve yield, terpene density, and bud quality across any genetics.
Veg VPD: 0.8–1.2 kPa. Higher humidity, lower leaf temperature. Plants transpire aggressively in veg — support it.
Early Flower: 1.0–1.5 kPa. Begin stepping down humidity as buds develop to reduce mold risk.
Late Flower: 1.2–1.6 kPa. Push VPD slightly higher to drive terpene and resin density in the final weeks.
Seed catalogue terminology explained — what F1, F2, BX, and S1 mean, why lineage matters for predicting pheno expressions, and how to read a genetics label like a breeder.
F1: First generation cross between two distinct parent lines. Typically shows hybrid vigour (heterosis) — fast growth, strong expression.
BX (Backcross): A cross bred back to one of its parent lines to stabilise and reinforce specific traits. BX2 and BX3 indicate successive backcross generations.
S1: A self-pollinated seed — a female plant pollinated with reversed pollen from the same plant. Highly consistent expression, often close to the original clone.
Terpenes determine aroma, flavour, and contribute significantly to the entourage effect that shapes a cultivar's experience. Learn the key terpenes and what they mean for your selection.
Myrcene: Earthy, musky, herbal. Most abundant terpene in cannabis. Associated with relaxing, sedative effects. Found in Starlight Sherb, Dark Matter Kush.
Limonene: Citrus, lemon, orange. Associated with elevated mood, stress relief. Found in Orion Gelato, Galaxy Runtz.
Caryophyllene: Spicy, pepper, woody. Unique in that it can bind to CB2 receptors. Found in Galaxy Runtz, Andromeda Cookies.
Terpinolene: Piney, floral, herbal. Common in haze-dominant varieties. Found in Nebula OG, Solar Flare Haze.
Harvesting at the right moment makes or breaks the final product. Too early and you lose potency and yield. Too late and the high profile shifts from clear to heavy. Here's how to read your plant's signals.
Trichome colour guide: Clear = not ready. Milky/cloudy = peak THC. Amber = THC degrading to CBN, effect becomes more sedative.
The window: Most premium cultivars have a 5–10 day harvest window. Waiting for 10–20% amber maximises the balance of potency and body effect.
Tools: A jeweller's loupe (60x minimum) or digital microscope is essential for accurate trichome assessment.
