We recommend not to touch the seeds or the seedlings with your hands. If you do anyways, make sure your hands are clean and if possible use plastic gloves.
– In a cup of water
Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Put the cannabis seeds on a surface that holds moisture, like wadding, paper towel or tissues on a saucer. Moisten the surface well, but avoid making it too wet. The moisture evaporates quickly at room temperature, so check during the period that the seeds will germinate if the surface is still damp enough. You can also cover the seeds with damp wadding or tissues and another saucer on top. Because of the moisture that gets into the seeds, they are activated and start to germinate. As soon as the germ is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Put them 0.5 to 1 cm in the soil with the root down. This way, the root will more easily grow downwards.
Germinating cannabis seeds on a damp surface
Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Use a clean room and area for the germination process. Fill a cup with water and put the cannabis seeds in it. After 3 to 5 days, the seeds should pop open and a tiny root should come out. As soon as the sprout is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Planting the germinated seed has to be done with lots of care and attention. Put them 0.5 to 1 cm in the soil with the root down. This way, the root (the white sprout) will more easily grow downwards.
My favorite way to germinate the seeds is to put them in a cup of water and then between a damp paper towel or tissue. This goes well in 99% of the cases. How long does it take cannabis seeds to germinate in general? Or how do we germinate autoflowering seeds? The time depends on the strain or type of seed, but autoflowering seeds germinate in the same way and time as feminized or regular cannabis seeds. That is why I will more extensively describe this first way.

– In soil
– On a damp surface
It does not break down naturally and therefore after Rockwool is created, it will remain in that form basically forever, filling up landfills without breaking down for thousands of years.
I used to believe that marijuana seeds were only “good” if they were extremely hard and very dark. One of the first tests I heard to check new cannabis seeds for viability was to try to crush them between my fingers. If the seeds could be crushed, they weren’t good, or so I was told. This has proven to be absolutely terrible advice!
Germination Method 3: Germination Station
I highly recommend using Rapid Rooters instead for your hydroponic application (or any grow setup), as they are much more user-friendly and tend to get far better germination rates.
Germination Method 1: Starter Cubes & Seedling Plugs (Recommended)
Most viable seeds will start out floating, and then eventually sink to the bottom of your glass after a few hours of soaking.
