Our preferred method of germination for each type of seed you wish to grow: CBD, autoflower or feminized. Follow these steps for consistent results every time.
Seeds need three things during germination
Keep seeds warm in a consistently heated environment. Room temperature or slightly above is ideal for germination.
Good air circulation is critical. Never seal seeds in airtight containers or plastic bags during germination.
Keep seeds damp but not swimming. A moist paper towel or spring water soak works perfectly.
DO NOT USE HEATPADS, REVERSE OSMOSIS WATER OR PLASTIC BAGS. USING ANY OF THESE WILL INVALIDATE YOUR GUARANTEE.
Place the seeds in a glass with natural spring water. DO NOT USE tap water, RO water or any other type of water. Let them soak for 15 hours. The seeds will float at first and sink as they become saturated. They won't sink straight away so don't get discouraged. You can push them down but it's better to wait around 4 hours before doing this.
We've found adding a drop of peroxide to the water can help germination if you're having trouble.
Take a paper towel, free from dyes and perfumes, place it on a plate and add the seeds from the glass. Use some water to moisten the paper towel. You don't want the towel too wet. The seeds should be kept damp but not swimming.
Use unbleached, plain paper towels for best results. Avoid colored or scented varieties.
Keep the seeds in a warm, dark room which has a good airflow. Don't put them in a drawer and if placing them in a closet, keep the door open to allow airflow. Keep the seeds warm and periodically check the seeds to make sure they do not dry out. This is a crucial step so be vigilant!
Check every 8–12 hours to ensure the paper towel hasn't dried out. Mist lightly if needed.
The seeds will develop tap roots within 2–3 days. Transfer them to plain potting soil. DO NOT USE ANYTHING HIGH IN NUTRIENTS. Soil with high level of nutrients can be too harsh for the seedlings. This can cause the seedlings to "burnout". Be gentle with them at first for the best results.
Use a pencil to make a small hole about 1/2 inch deep. Place the seed tap-root down and lightly cover with soil.
Always use natural spring water. Tap water contains chlorine and other chemicals that can inhibit germination. RO water lacks essential minerals.
A single drop of hydrogen peroxide in the soaking water can help soften the seed shell and promote faster germination.
Seeds won't sink immediately when soaking — this is normal. Wait at least 4 hours before pushing them down. Germination takes time.
Seedlings are fragile. High-nutrient soil will burn them out. Use plain potting soil for the first few weeks, then gradually introduce nutrients.
Tips and experiences from fellow growers
“This is exactly how I germinate my seeds. Last time I germinated 16 seeds and got 16 plants growing. This method works perfectly!”
“We've always just popped the seed directly into their forever home and had great results!”
“I scuff with sandpaper then soak the seeds in spring water for 24 hrs then into the forever home. 18 for 18 with this method. Easiest for newbies.”
“I grow hydroponically. I place the seeds in the water till I get a tail, about two to three days, then place in Rockwool, wait for roots to show, then place in grow tent. Doing it this way for fourteen years.”
