You can germinate cannabis seeds with wads of cotton wool and the small tray where the weed seeds from Dutch Headshop are supplied and afterwards you can continue the germination in Sprout pads.

Prepare the small tray with wads of cotton wool from Dutch Headshop weed seeds. This is quite fast.
Pour some (spring) water into the small tray with the wads of cotton wool.

Put the cannabis seeds in the small tray.

Put the wads of cotton wool on top of the weed seeds and press lightly, so that the top wad of cotton wool is damp.

Put the lid on the small tray and place it in the bag.

Place the small tray in a warm, dark place.
Wait patiently and don't stir the weed seeds too much. The earliest you should check it is after 24 hours, there won't be much happening before that.

Here, I check the small tray with wads of cotton wool from the Dutch-Headshop brand of weed seeds. You can see that it is moist and warm.

After approximately 24 hours, there isn't much to see, just some small white dots. It is better to wait a while before transferring the weed seeds to the Sprout pads.

On the morning of day 3, or 38 hours after beginning the process, as you will see below, I prepare the Sprout pads and transfer the first Dutch Headshop weed seeds from the small tray. 
I have placed the Sprout pads on a plate and moistened them with spring water. They will absorb all the water and expand.

I have to transfer 1 weed seed because it has a nice root and cannot wait much longer.

With a stick, I make a hole of about 1 cm in the Sprout Pad.

Next, I cover the weed seed gently.

On the evening of day 3, I transfer another 2 weed seeds to the Sprout pads. The weed seeds with roots, on the top right, have been placed in the Sprout Pads.

It is the morning of day 4 all the weed seeds that have germinated in the wad of cotton wool in the small plastic tray have a root!
It’s going well!
Now I will check if all the weed seeds with a root are ready to grow in the coconut fibre Sprout Pads.
The last 7 weed seeds with a root.

The weed seeds have to be placed root downward into the Sprout Pads.

Here you have all 10 Sprout pads with rooted weed seeds in it. The weed seeds placed first are not yet visible above the coconut fibre. I make sure that the Sprout pads are not too dry, they should remain fairly moist.

Day 5, and now we can see something appearing above the ground!
See below the photos and comments. The outlook is good, we can already see some seedlings!
In the coco Sprout pads, with approximately 1 cm rooted weed seeds in it, two pieces show a very small seedling. I keep the pads on the plate fairly moist because the Sprout pads tend to dry out over the radiator / heater fairly quickly. I water each Sprout pad with a little spring water with the 50 ml measuring cup.

All 10 of the weed seeds in the Sprout pads have come up! Yesterday we saw only two seedlings just above the coco and, less than 24 hours later, the other eight weed seeds have also found the light. Excellent outcome.

All 10 of the seedlings in the Sprout Pads are growing and almost show the first true hemp leaves. You can see them all going in search of the light; I've put them close to the lens for the picture. The cuttings are well on their way to becoming beautiful weed plants.

At the bottom of the sprout path we can see a nice root coming through.
