How to Germinate Marijuana Seeds the Easy Way

There are many opinions about how to germinate marijuana seeds.

Some people advocate putting cannabis seeds in between two wet paper towels.

Others say put them in a glass of water.

Such methods force you to handle your seeds when they’ve just sprouted.

The seeds have to be carefully plucked from the paper towels or water, and just as carefully placed into a growing media.

The extra handling creates opportunities for germinated seeds to be damaged.

The simplest methods that work well are always the best methods.

That’s why I germinate marijuana seeds in the media they’ll grow in.

If the final destination for my seedlings is soil, soilless mix, or coco coir, I put the appropriate material in a JiffyPot and water them from the bottom with reverse osmosis water at 6.1 pH.

You may notice it’s impossible to get accurate pH readings on zero parts per million reverse osmosis water.

I add beneficial microbes such as Voodoo Juice, Piranha, and Tarantula until I get enough parts per million to make my pH readings accurate.

The added benefit of using beneficial microbes products is they protect cannabis roots and root zones, and speed up root development.

If the final destination for my marijuana seedlings is a pure hydroponics system such as deep water culture or an ebb and flow hydro system using rockwool, I plant my seeds into a rockwool cube.

Not the smallest size ones either. I like the larger sizes.

Look here for detailed information that helps you germinate marijuana seeds using rockwool cubes.

Note that rockwool must be pre-treated before use to get its pH where you want it.

Look here for instructions on how to condition rockwool.

The best depth for planting marijuana seed is 3/8^th to ½ inch below the surface line.

The best temperature range to germinate marijuana seeds is 74-76°F, but they can germinate up to 80°F. Warmer than that is too warm.

If you don’t have precision temperature control where your seeds are germinating and temps are too cool, you could use a seedling heat mat.

Be careful to control the seed zone temperature when using a seedling heat mat.

It’s best to get a seedling heat mat with built-in thermostat.

Don’t Drown Your Cannabis Seeds

The biggest mistake growers make when they germinate marijuana seeds is overwatering.

The rockwool cube, soil, soilless mix, or coco that you germinate marijuana seeds in shouldn’t be soaking wet.

The media should be totally damp, but not soaking wet.

If the media is too wet, seeds might rot or drown.

If you have healthy seeds, they should germinate in 2-5 days.

Old or inferior seeds can take as long as 10-11 days.

If they’ve been moist that long and haven’t germinated, they’re most likely not going to.

If your seeds are old or otherwise not fresh or reliable, look at this kit that can help them germinate.

As soon as your seeds germinate, put them under a Hortilux PowerVeg lighting fixture, or some other T-5 or low-power LED, for at least 2-3 weeks until you’re sure your seedlings’ root systems and leaf structures can handle full HID, LED, or sunlight.

Rather than using the paper towel or submerse in water methods, this method we’ve given you to germinate marijuana seeds is direct, easy, and doesn’t require you to handle, transplant, and possibly damage a sprouted marijuana seed.
