5) Check moisture level of towels several times a day, watering once or twice to keep them evenly moist. DO NOT LET THE TOWELS DRY OUT! Let excess water drain away freely. The paper or cloth towels will retain enough moisture to germinate the seeds in a few days. Each seed contains an adequate food supply for germination. Prevent fungal attacks by watering with a mild 2 percent bleach or organic fungicide solution.

1) Soak seeds overnight in a glass of plain water. They may float on the surface at first but should sink to the bottom in a few minutes. Make sure seeds get good and wet so that water penetrates the outer shell and growth is activated. Do not let seeds soak for more than 24 hours, or they might get too wet, suffer oxygen deprivation and subsequently rot.

Other Tips for Germinating Cannabis Seeds

3) Drain the water from the dinner plate by tipping it to the side.

Some seeds have a very hard outer shell (testa) and are difficult to germinate. Such testy cases can be softened or scarified to allow water to penetrate. To scarify, line a matchbox with a piece of fine-grain sandpaper or emery board. Put the seeds in the matchbox and shake for 10 to 15 seconds. Remove the seeds and make sure they have been scuffed a bit. Just a little scuffing will allow water to enter and set germination in motion.

3) Shake matchbox for 10 to 15 seconds to scarify the seeds.

Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.

Was the seed found in good weed?

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

Rockwool is not a natural material – it’s made by heating rock and chalk to 3,000°F and air is blown through the mixture to create thin fibers of rocky material

Check on germinating seeds once every 12 hours or so (don’t disturb them or their roots). You can plant any seeds which have sprouted right away, or leave them for another day or two, to let the others keep up.

Germination Method 3: Germination Station

After you see that your cannabis seeds have sprouted, you should plant them right away.

It’s a steady 85 degrees F in there, no idea about the humidity in the bottles.

Another method to germinate marijuana seeds is to soak them overnight in slightly warm water, usually done in a glass drinking cup.
