How to Grow Cannabis From Seed

The Joynt Seed Co. | Yellow Springs, Ohio

Growing your own cannabis can be a rewarding hobby. Whether you're growing your first plant or your fiftieth, success starts with healthy genetics, patience, and a little know-how.

This guide covers the basics to help you get started.

Step 1: Germinate Your Seeds

Germination is simply the process of waking your seeds up and encouraging them to sprout.

Paper Towel Method (Recommended)

You'll Need:

  • Two paper towels

  • A plate or container

  • Water

  • Your Joynt Seeds

Instructions

  1. Dampen two paper towels with water.

  2. Place your seeds between the towels.

  3. Put the towels on a plate or inside a container.

  4. Store in a warm, dark location (70-80°F).

  5. Check daily to ensure towels remain moist.

Most seeds will sprout within 24-72 hours.

Once the taproot is approximately ¼-½ inch long, it's time to plant.

⚠️ Avoid touching the root whenever possible.

Step 2: Plant Your Seed

Recommended Soil

For beginners, quality potting soil is easiest.

Look for:

  • Well-draining soil

  • Light texture

  • Good moisture retention

Plant the seed:

  • Root facing down

  • About ¼ inch deep

  • Cover lightly with soil

  • Water gently.

Step 3: Light Requirements

🌱 Autoflower Seeds

Autoflower plants begin flowering automatically based on age rather than light cycle.

Recommended Schedule

  • 18 Hours Light

  • 6 Hours Darkness

Many growers maintain this schedule from seedling through harvest.

Some growers even run:

  • 20 Hours Light / 4 Hours Darkness

Autoflowers are great for beginners because there's no need to change the lighting schedule.

Typical Lifecycle

Seed → Harvest:
8-12 weeks

Feminized Photoperiod Seeds

Photoperiod plants rely on changes in light exposure to trigger flowering.

Vegetative Stage

Use:

  • 18 Hours Light

  • 6 Hours Darkness

This encourages the plant to continue growing larger.

Flowering Stage

When you're ready for the plant to begin producing flowers, switch to:

  • 12 Hours Light

  • 12 Hours Darkness

This change signals the plant to begin flowering.

Typical Lifecycle

Vegetative Stage:
4-8+ weeks (grower's choice)

Flowering Stage:
8-10+ weeks

Total Grow Time:
Typically 3-5 months
