Why germinate marijuana seeds in a paper towel?

Full visibility of the process

Unlike soil germination, the paper towel method gives you a clear view of each stage. You’ll see exactly when the seed cracks and how the taproot is developing.

Simple and inexpensive

There’s no need for special gear—just basic household items and a little patience. Ideal for home growers or those germinating multiple seeds.

Great for multiple seeds

When germinating several cannabis seeds in paper towels, you can monitor and select the strongest sprouts—especially useful when working with premium strains from Mavericks Genetics.

What you need for paper towel germination

• Cannabis seeds from Mavericks Genetics

• 2 clean paper towels (plain, unprinted)

• 1 resealable plastic bag or airtight container

• Clean water (filtered or bottled)

• A plate or plastic container

• Warm, dark location for incubation

Step-by-step: How to germinate marijuana seeds in paper towel

Step 1: Moisten the paper towels

Dampen two paper towels with clean, room-temperature water. Wring them out—towels should be moist, not dripping. Too much water may cause mould or seed rot.

Step 2: Place the seeds between the towels

Lay one damp paper towel on a clean plate or inside a container. Place the seeds on top, spaced apart. Cover them with the second towel.
Tip: Use clean hands or tweezers to avoid contaminating the seeds.

Step 3: Seal the setup

Place the towels inside a resealable plastic bag or loosely lidded container. This maintains humidity while still allowing some airflow.
You may poke a small hole in the bag, but it’s optional if you open it daily.

Step 4: Store in a warm, dark place

Place your setup somewhere dark and warm—like a cupboard or on top of a fridge. Ideal temperature: 21–25°C (70–78°F).
Avoid direct sunlight or heated surfaces that can dry out the towels.

Step 5: Check daily for sprouts

Open the bag or container once per day to check the seeds. Be gentle—don’t touch the roots. The first taproot may appear in 24 to 72 hours, but some seeds take up to 7 days.
Once the taproot reaches 0.5 to 1.25 cm (¼ to ½ inch), it’s time to transplant.

How long does germination take?

Most cannabis seeds will germinate within 1 to 5 days using this method.

• Fresh, high-quality seeds (like those from Mavericks Genetics) often sprout within 24–48 hours

• Older or hard-coated seeds may take up to 7 days

• If nothing happens after 10 days, the seed is likely non-viable

How to transplant sprouted seeds

Step 1: Prepare your growing medium

Set up your soil, coco, or rockwool cubes. The medium should be moist, not soggy. Make a small hole about 1.25 cm (½ inch) deep.

Step 2: Handle with care

Use clean tweezers or a small spoon to move the seedling. Avoid touching the taproot—it’s very delicate.

Step 3: Plant taproot-down

Gently place the seed with its taproot pointing downward. Lightly cover with soil, keeping the surface loose and breathable.

Step 4: Maintain warmth and humidity

Keep humidity between 65–75% and temperature around 22–26°C (72–78°F). Mist the surface daily and provide gentle lighting.

Touching the taproot

Problem: Damaged root leads to poor growth

Planting too deep

Problem: Seedling may not reach light
Solution: Cover lightly with soil—don’t compact

Pro tips for better results

• Label your seeds if germinating multiple strains from Mavericks Genetics

• Always use tweezers or gloves to handle sprouted seeds

• Use a seedling heat mat if your environment drops below 21°C

• Don’t transplant too early—wait until the taproot is well developed
