Know Your Seeds

Which Seed Type Is Right For You?

Every seed type has unique growing characteristics. Understanding the differences is the first step to a successful harvest.

Most Popular

Feminized Seeds

Engineered to produce 100% female plants, eliminating the guesswork of identifying and removing males. Every plant grows to produce resinous, seedless buds — perfect for maximizing your grow space and your harvest weight.

Autoflower Seeds

Ideal for Canadian growers dealing with short seasons. Autoflowers transition from seed to harvest in under 9 weeks with no light cycle changes needed — they flower automatically based on age, not the hours of daylight they receive.

Step-by-Step

The Complete Seed-to-Harvest Guide

Follow each stage carefully. Cannabis cultivation rewards patience and attention — skip a step and your plants will tell you.

01
Stage

Germination

Germination is where everything begins. Place seeds between two damp paper towels on a plate, keep them in a warm dark spot (21–27°C), and check every 12 hours. A white taproot should emerge within 24–72 hours. Never let the towels dry out completely or become waterlogged.

⏱ 24–72 hours 🌡 21–27°C 💧 Damp, not soaking 🌑 Complete darkness
02
Stage

Seedling Stage

Transfer your germinated seed taproot-down into a small pot of light, airy medium. Seedlings need gentle light (18 hrs/day), minimal watering, and high humidity (65–70% RH). The first true fan leaves will appear within days. Avoid overwatering — the most common seedling killer.

⏱ 1–2 weeks 💡 18 hrs light/day 💦 65–70% humidity 🪴 Small pots only
03
Stage

Vegetative Growth

This is when your plant builds its structural foundation. Increase light intensity, begin low-stress training (LST) if desired, and start a nitrogen-rich feeding schedule. Photoperiod plants stay in veg as long as they receive 18+ hours of light per day, giving you full control over plant size.

⏱ 2–8 weeks 💡 18/6 light schedule 🌿 High nitrogen feed ✂️ LST / topping optional
04
Stage

Pre-Flower & Sex Identification

Switch photoperiod plants to a 12/12 light schedule to trigger flowering. In the first 1–2 weeks, pre-flowers will appear at the nodes. Female pre-flowers show two white pistils; males produce small pollen sacs. Remove males immediately unless intentionally breeding — a single male can pollinate an entire garden.

⏱ 1–2 weeks 💡 Switch to 12/12 👀 Identify sex daily 🚫 Remove males fast
05
Stage

Flowering

Buds develop rapidly over 6–10 weeks depending on strain. Shift to a phosphorus and potassium-heavy feed, reduce humidity to 40–50% to prevent mould, and watch trichome development closely using a loupe. This stage determines your final potency, aroma, and yield weight.

⏱ 6–10 weeks 💡 12/12 maintained 🌸 High P/K nutrients 💦 40–50% humidity
06
Stage

Flushing

In the final 1–2 weeks before harvest, flush your medium with pH-balanced plain water. This clears residual nutrients from the plant tissue and growing medium, leading to a cleaner, smoother final product with better flavour. Skip this step if growing in living soil — the biology handles it for you.

⏱ 7–14 days before harvest 💧 Plain water only ⚗️ pH 6.0–6.5 🌍 Skip for living soil
07
Stage

Harvest Timing

The single most impactful decision you'll make. Use a jeweller's loupe or digital microscope to examine trichomes: all clear means too early; mostly milky means peak THC; milky with 20–30% amber means a more sedative, relaxing effect. Always harvest in darkness for best results — it can measurably improve trichome density.

🔬 Milky trichomes = peak THC 🟡 30% amber = relaxing 🌑 Harvest in darkness ✂️ Use clean scissors
08
Stage

Drying & Curing

Hang trimmed branches upside down in a dark room at 15–21°C with 45–55% RH for 7–14 days. Once stems snap rather than bend, move buds into glass mason jars. Burp jars daily for 2–4 weeks — proper curing is the single biggest improvement most growers can make to their final product's flavour, aroma, and smoothness.

⏱ 2–6 weeks total 🌡 15–21°C dry temp 💦 45–55% RH 🫙 Burp mason jars daily

Pro Tips for a Better Harvest

The difference between a good grow and a great one comes down to these fundamentals — beginners and veterans alike benefit from revisiting them.

Always pH Your Water

Cannabis roots absorb nutrients most efficiently within a specific pH range. Target 6.0–7.0 for soil, and 5.5–6.5 for hydroponics. pH drift is the leading cause of nutrient lockout in beginner grows — a $15 meter pays for itself on the first run.

Airflow Is Non-Negotiable

Poor airflow causes mould, mildew, and weak stems. Run an oscillating fan on your plants continuously during lights-on periods. Aim for gentle leaf movement — not violent wind. Exhaust and replace your grow room air every 1–3 minutes during peak flowering.

Mind Your VPD

Vapour Pressure Deficit (VPD) is the relationship between temperature and humidity. Dialling in the correct VPD for each stage of growth dramatically improves transpiration, nutrient uptake, and overall plant health. Free VPD charts are widely available online.

Train, Don't Stress

Low-stress training (LST) and Screen of Green (ScrOG) techniques increase light penetration and dramatically improve yields without shocking the plant. Avoid heavy defoliation during flower — removing fan leaves mid-bloom can stunt bud development at a critical window.

Keep a Grow Journal

Log every feeding, watering, temperature reading, and observation. Patterns become visible over time — you'll know exactly what to replicate and what to fix before small issues become full-blown problems on your next run.

Invest in a Loupe or Scope

A 30–60× jeweller's loupe or digital USB microscope costs under $20 and will transform your harvest timing. Reading trichome maturity is the only reliable way to harvest cannabis at exactly the right moment for your desired potency and effect profile.

Common Questions

Frequently Asked Questions

Answers to the questions every Canadian grower asks before their first — and second — harvest.

Under the Cannabis Act (2018), Canadian adults aged 18 or 19 and older (depending on province) are legally permitted to grow up to four cannabis plants per household for personal use from licensed seed or seedlings. Plants must not be visible from a public place. Some provinces and municipalities have additional restrictions, and Quebec and Manitoba have provincial laws prohibiting home cultivation — always check your local regulations before starting a grow.
Autoflowering feminized seeds are the best choice for beginners in Canada. They don't require a light schedule change to trigger flowering, they finish in 60–75 days from seed, and their compact size suits small indoor tents. Indica-dominant autoflowers like Northern Lights Auto or Blueberry Auto are particularly well-suited to Canada's climate — they're cold-tolerant, fast, and beginner-friendly.
Yes — outdoor growing is legal and very rewarding in the right provinces. British Columbia, Ontario, and Quebec's southern regions offer long enough frost-free windows for photoperiod strains. In shorter-season provinces like Saskatchewan, Manitoba, and Alberta, autoflowering strains are strongly recommended as they complete their full cycle well within the available warm months. Start seeds indoors under lights in late April, transplant after last frost, and you can harvest by late August or September.
A basic 2×4 ft tent setup for 2–4 plants typically costs $300–600 CAD all-in, including the tent, an LED grow light, inline fan and filter, fabric pots, and growing medium. Mid-range setups with a quality LED (like a Spider Farmer SF-2000 or similar) and proper environmental controls run $600–1,200. The initial investment is usually recovered after two or three successful harvests at current retail cannabis prices.
The most reliable method is examining trichomes with a 30–60× jeweller's loupe or digital microscope. Trichomes start clear (too early), turn milky white (peak THC, energetic effect), and then gradually amber (higher CBN, more sedative). Most growers harvest when trichomes are mostly milky with 10–30% amber, depending on the desired effect. Pistil colour (the hair-like structures on buds turning from white to orange) provides a rough guide but is less accurate than trichome inspection.
Traditionally, indica strains are associated with relaxing, body-focused effects often described as a "body high," while sativas are linked to uplifting, cerebral, energetic experiences. In practice, today's cannabis is almost entirely made up of hybrids, and the actual cannabinoid and terpene profile of a specific strain matters far more than its indica/sativa classification. Myrcene-dominant strains tend toward sedation regardless of lineage; limonene and pinene-forward strains lean toward uplifting effects. Use the indica/sativa label as a rough starting point, not a guarantee.
