If the seedling leaves aren’t opening up because they’re stuck inside the seed membrane, wet the membrane and give it a few minutes soften up. Then use tweezers to gently remove the membrane. In some cases, it’s easier to stick the tweezers inside and pry the leaves apart just like with a shell.

Why a seedling heat mat? Seeds germinate significantly faster when they’re kept 70-85°F (20-30°C). A seedling heat mat keeps seeds warm during the germination process. However, any warm spot works just as well (for example, on top of the refrigerator is the perfect temperature for some people). When you touch the wet paper towels, they should feel warm but not burning hot.

Just 12 hours later, several seedlings have already appeared above ground.

9.) You Have Seedlings!

Ensure paper towels don’t dry out. You may have to add more water occasionally to keep them wet. You can usually tell when the seeds have germinated without looking under the top sheet. This means you can check on your seeds regularly without disturbing them by picking up the top plate.

If there’s a short root or seedling hasn’t germinated yet, put the paper towel back and gave the seedling one more day. Seedlings grow faster if they have a bit more root before being planted.

Rapid Rooters (note: extra Rapid Rooters can be stored in a cool place for future grows)

Cheap paper towels (don’t use the expensive cloth-like ones!)

Wet paper towels are probably the most common way of germinating cannabis seeds

Growing your own weed is fairly easy, as explained in our article ‘All You Need For Growing Weed At Home‘. The hardest part for some growers though, is germinating their newly bought cannabis seeds. After all, the vulnerable seedlings are easily damaged. However, making sure your cannabis seeds survive germination is essential for a successful grow. In this blog, we highlight three tested methods that let anyone germinate cannabis seeds with minimal effort.

How To Germinate Cannabis Seeds: Wet (Paper) Towel Germination

Plugs are a practical way to germinate cannabis seeds

The top layer is the perfect place to germinate cannabis seeds, as it dries out faster than the soil further down the pot. This makes it easier to ensure the right level of moisture for the seed to germinate. If it gets too wet, the seeds will rot in the soil. If it stays too dry, the plant will not be triggered to emerge from its shell. Again, it’s all about finding the perfect balance between too wet and too dry.

Cannabis seeds and sprouted seedlings require constant temperatures of around 20-25 degrees Celsius
